commit fdfe14f1e17ba5a2f8dfa0bdb799c6b0e730211b
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Jul 9 13:52:39 2015 -0500
Added support for Intel Haswell/Broadwell.
Details:
- Added sgemm and dgemm micro-kernels, which employ 256-bit AVX vectors
and FMA instructions. (Complex support is currently provided by default
induced method, 4m1a.)
- Added a 'haswell' configuration, which uses the aforementioned kernels.
- Inserted auto-detection support for haswell configuration in
build/auto-detect/cpuid_x86.c.
- Modified configure script to explicitly echo when automatic or manual
configuration is in progress.
- Changed beta scalar in test_gemm.c module of test suite to -1.0 to 0.9.

Date: Tue Jul 7 10:06:53 2015 -0500
Added 'carrizo' configuration.
Details:
- Added a new configuration for AMD Excavator-based hardware also known
as Carrizo when referring to the entire APU. This configuration uses
the same micro-kernels as the piledriver, but with different
cache blocksizes.

commit 7cd01b71b5e757a6774625b3c9f427f5e7664a76
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Jun 19 11:31:53 2015 -0500
Implemented dynamic allocation for packing buffers.
Details:
- Replaced the old memory allocator, which was based on statically-
allocated arrays, with one based on a new internal pool_t type, which,
combined with a new bli_pool_*() API, provides a new abstract data
type that implements the same memory pool functionality but with blocks
from the heap (ie: malloc() or equivalent). Hiding the details of the
pool in a separate API also allows for a much simpler bli_mem.c family
of functions.
- Added a new internal header, bli_config_macro_defs.h, which enables
sane defaults for the values previously found in bli_config. Those
values can be overridden by #defining them in bli_config.h the same
way kernel defaults can be overridden in bli_kernel.h. This file most
resembles what was previously a typical configuration's bli_config.h.
- Added a new configuration macro, BLIS_POOL_ADDR_ALIGN_SIZE, which
defaults to BLIS_PAGE_SIZE, to specify the alignment of individual
blocks in the memory pool. Also added a corresponding query routine to
the bli_info API.
- Deprecated (once again) the micro-panel alignment feature. Upon further
reflection, it seems that the goal of more predictable L1 cache
replacement behavior is outweighed by the harm caused by non-contiguous
micro-panels when k % kc != 0. I honestly don't think anyone will even
miss this feature.
- Changed bli_ukr_get_funcs() and bli_ukr_get_ref_funcs() to call
bli_cntl_init() instead of bli_init().
- Removed query functions from bli_info.c that are no longer applicable
given the dynamic memory allocator.
- Removed unnecessary definitions from configurations' bli_config.h files,
which are now pleasantly sparse.
- Fixed incorrect flop counts in addv, subv, scal2v, scal2m testsuite
modules. Thanks to Devangi Parikh for pointing out these
miscalculations.
- Comment, whitespace changes.
commit 9848f255a3bab17d1139c391cca13ff3f1ffe6ed
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Jun 11 19:14:22 2015 -0500
Added early return to API-level _init() routines.
Details:
- Added conditional code that returns early from the API-level _init()
routines if the API is already initialized. Actually meant for this to
be included in 5f93cbe8.
commit 5f93cbe870f3478870e15581e7fd450dad5bba1e
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Jun 11 18:52:12 2015 -0500
Introduced API-level initialization.
Details:
- Added API-level initialization state to _const, _error, _mem, _thread,
_ind, and _cntl APIs. While this functionality will mostly go unused,
adding miniscule overhead at init-time, there will be at least once
instance in the near future where, in order to avoid an infinite loop,
a certain portion of the initialization will call a query function that
itself attempts to call bli_init(). API-level initialization will allow
this later stage to verify that an earlier stage of initialization has
completed, even if the overall call to bli_init() has not yet returned.
- Added _is_initialized() functions for each API, setting the underlying
bool_t during _init() and unsetting it during _finalize().
- Comment, whitespace changes.
commit ee129c6b028bc5ac88da7c74fde72c49803742ff
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Jun 10 12:53:28 2015 -0500
Fixed bugs in _get_range(), _get_range_weighted().
Details:
- Fixed some bugs that only manifested in multithreaded instances of
some (non-gemm) level-3 operations. The bugs were related to invalid
allocation of "edge" cases to thread subpartitions. (Here, we define
an "edge" case to be one where the dimension being partitioned for
parallelism is not a whole multiple of whatever register blocksize
is needed in that dimension.) In BLIS, we always require edge cases
to be part of the bottom, right, or bottom-right subpartitions.
(This is so that zero-padding only has to happen at the bottom, right,
or bottom-right edges of micro-panels.) The previous implementations
of bli_get_range() and _get_range_weighted() did not adhere to this
implicit policy and thus produced bad ranges for some combinations of
operation, parameter cases, problem sizes, and n-way parallelism.
- As part of the above fix, the functions bli_get_range() and
_get_range_weighted() have been renamed to use _l2r, _r2l, _t2b,
and _b2t suffixes, similar to the partitioning functions. This is
an easy way to make sure that the variants are calling the right
version of each function. The function signatures have also been
changed slightly.
- Comment/whitespace updates.
- Removed unnecessary '/' from macros in bli_obj_macro_defs.h.

Minor cleanup to bli_init() and friends.
Details:
- Spun-off initialization of global scalar constants to bli_const_init()
and of threading stuff to bli_thread_init().
- Added some missing _finalize() functions, even when there is nothing
to do.
commit 1213f5cebabc1637ce9dd45c4bfa87bb93677c29
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Jun 2 13:27:47 2015 -0500
POSIX thread bugfixes/edits to bli_init.c, _mem.c.
Details:
- Fixed a sort-of bug in bli_init.c whereby the wrong pthread mutex
was used to lock access to initialization/finalization actions.
But everything worked out okay as long as bli_init() was called by
single-threaded code.
- Changed to static initialization for memory allocator mutex in
bli_mem.c, and moved mutex to that file (from bli_init.c).
- Fixed some type mismatches in bli_threading_pthreads.c that resulted
in compiler warnings.
- Fixed a small memory leak with allocated-but-never-freed (and unused)
pthread_attr_t objects.
- Whitespace changes to bli_init.c and bli_mem.c.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Apr 10 13:23:50 2015 -0500
Tweaks to test/3m4m to test with adjusted dims.
Details:
- Updated test/3m4m driver files to build test drivers that allow
comparision of real "asm_blis" results to complex "asm_blis" results,
except with the latter's problem sizes adjusted so that problems are
generated with equal flop counts.
commit 426b6488580a92bf071a62dc319a9c837ce39821
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Apr 8 15:12:21 2015 -0500
Fixed a packing bug that manifested in trsm_r.
Details:
- Fixed a bug that caused a memory leak in the contiguous memory
allocator. Because packm_init() was using simple aliasing when
a subpartition object was marked as zeros by bli_acquire_mpart_*(),
the "destination" pack object's mem_t entry was being overwritten
by the corresponding field of the "source" object (which was likely
NULL). This prevented the block from being released back to the
memory allocator. But this bug only manifested when changing the
location of packing B from outside the var1 loop to inside the
var3 loop, and only for trsm with triangular B (side = right). The
bug was fixed by changing the type of alias used in packm_init()
when handling zero partition cases. Specifically, we now use
bli_obj_alias_for_packing(), which does not clobber the destination
(pack) object's mem_t field. Thanks to Devangi Parikh for this bug
report.

commit 26a4b8f6f985597f80e0174990bf541f1d9bafac
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Apr 1 10:44:54 2015 -0500
Implemented 3m2, 3m3 induced algorithms (gemm only).
Details:
- Defined a new "3ms" (separated 3m) pack schema and added appropriate
support in packm_init(), packm_blk_var2().
- Generalized packm_struc_cxk_3mi to take the imaginary stride (is_p)
as an argument instead of computing it locally. Exception: for trmm,
is_p must be computed locally, since it changes for triangular
packed matrices. Also exposed is_p in interface to dt-specific
packm_blk_var2 (and _var1, even though it does not use imaginary
stride).
- Renamed many functions/variables from _3mi to _3mis to indicate that
they work for either interleaved or separated 3m pack schemas.
- Generalized gemm and herk macro-kernels to pass in imaginary stride
rather than compute them locally.
- Added support for 3m2 and 3m3 algorithms to frame/ind, including 3m2-
and 3m3-specific virtual micro-kernels.
- Added special gemm macro-kernels to support 3m2 and 3m3.
- Added support for 3m2 and 3m3 to testsuite.
- Corrected the type of the panel dimension (pd_) in various macro-
kernels from inc_t to dim_t.
- Renamed many functions defined in bli_blocksize.c.
- Moved most induced-related macro defs from frame/include to
frame/ind/include.
- Updated the _ukernel.c files so that the micro-kernel function pointers
are obtained from the func_t objects rather than the cpp macros that
define the function names.
- Updated test/3m4m driver, Makefile, and run script.

commit f1a6b7d02861ccebdc500ea98778cc0f6cddad17
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Mar 18 15:37:10 2015 -0500
Reorganized code for induced complex methods.
Details:
- Consolidated most of the code relating to induced complex methods
(e.g. 4mh, 4m1, 3mh, 3m1, etc.) into frame/ind. Induced methods
are now enabled on a per-operation basis. The current "available"
(enabled and implemented) implementation can then be queried on
an operation basis. Micro-kernel func_t objects as well as blksz_t
objects can also be queried in a similar maner.
- Redefined several micro-kernel and operation-related functions in
bli_info_*() API, in accordance with above changes.
- Added mr and nr fields to blksz_t object, which point to the mr
and nr blksz_t objects for each cache blocksize (and are NULL for
register blocksizes). Renamed the sub-blocksize field "sub" to
"mult" since it is really expressing a blocksize multiple.
- Updated bli_*_determine_kc_[fb]() for gemm/hemm/symm, trmm, and
trsm to correctly query mr and nr (for purposes of nudging kc).
- Introduced an enumerated opid_t in bli_type_defs.h that uniquely
identifies an operation. For now, only level-3 id values are defined,
along with a generic, catch-all BLIS_NOID value.
- Reworked testsuite so that all induced methods that are enabled
are tested (one at a time) rather than only testing the first
available method.
- Reformated summary at the beginning of testsuite output so that
blocksize and micro-kernel info is shown for each induced method
that was requested (as well as native execution).
- Reduced the number of columns needed to display non-matlab
testsuite output (from approx. 90 to 80).
commit 8d5169ccda954e5f72944308a036dcb7ebfc9097
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Mar 18 11:38:08 2015 -0500
Fixed bug in release of mem_t buffer.
Details:
- Fixed a bug that affects all level-2 and level-3 blocked variants. The
bug only manifested, however, if the packing of operands (A and B in
gemm, for example) spanned multiple nodes in the control tree. Until
recently, the main consumers of packm were level-3 operations, all of
which packed both input operands from blocked variant 1 (B outside of
the loop, and A within the loop). This particular usage masked a flaw
in the code whereby bli_obj_release_pack() would always release the
underlying mem_t buffer (provided it was allocated), even if the buffer
was not allocated in the current variant. This has been fixed by
replacing all calls to bli_obj_release_pack() with calls to a new
function, bli_packm_release(), which takes the same control tree node
argument passed into the object's corresponding call to packm_init()
or packv_init(). bli_packm_release() then proceeds to invoke
bli_obj_release_pack() only if the control tree node indicates that
packing was requested. Thanks to Devangi Parikh for identifying this
bug.

Minor updates to induced complex mode management.
Details:
- Relocated bli_4mh.c, bli_4mb.c, bli_4m.c, bli_3mh.c, bli_3m.c (and
associated headers) from frame/base to frame/base/induced.
- Added bli_xm.? to frame/base/induced, which implements
bli_xm_is_enabled(), which detects whether ANY induced complex method
is currently enabled.
- The new function bli_xm_is_enabled() is now used in bli_info.c to
detect when an induced complex method is used, so we know when to
return blocksizes from one of the induced methods' blocksize objects.

Added max(mr,nr) to kc in static mem pools.
Details:
- Changed the static memory definitions to compute the maximum register
blocksize for each datatype and add it to kc when computing the size
of blocks of A and B. This formally accounts for the nudging of kc
up to a multiple of mr or nr at runtime for triangular operations
(e.g. trmm).

Renamed 3m and 4m symbols/macros to 3mi and 4mi.
Details:
- Renamed several variables and macros from 3m/4m to 3mi/4mi. This is
because those packing schemas were always implicitly "interleaved".
This new naming scheme will make way for new schemas that separate
instead of interleve the real and imaginary (and summed) parts.
- Expanded the pack format sub-field of the pack schema field of the
info_t to 4 bits (from 3). This will allow for more schema types
going forward.
- Removed old _cntl.c files for herk3m, herk4m, trmm3m, trmm4m.

Fixed indexing bug for trmm3 via 3mh, 4mh.
Details:
- Fixed a bug that only affected trmm3 when performed via 3mh or 4mh,
whereby micro-panels of the triangular matrix were packed with "dead
space" between them due to failing to adjust for the fact that pointer
arithmetic was occurring in units of complex elements while the data
being packed consisted of real elements. It turns out that the macro-
kernel suffered from the same bug, meaning the panels were actually
being packed and read consistently. The only way I was able to
discover the bug in the first place was because the packed block of A
was overflowing into the beginning of the packed row panel of B using
the sandybridge configuration.

Fixed an obscure bug in 3mh/3m/4mh/4m packing.
Details:
- Modified bli_packm_blk_var1.c and _var2.c to increase the triangular
case's panel increment by 1 if it would otherwise be odd. This is
particularly necessary in _var2.c when handling the interleaved 3m
or ro/io/rpi pack schemas, since division of an odd number by 2 can
happen if both the panel length and the panel packing dimension
(register packing blocksize) are odd, thus making their product odd.
- Modified bli_packm_init.c so that panel strides are increased by 1
if they would otherwise be odd, even for non-3m related packing.
- Modified the trmm and trsm macro-kernels so that triangular packed
micro-panels are traversed with this new "increment by 1 if odd"
policy.
- Added sanity checks in trmm and trsm macro-kernels that would result
in an abort() if the conditions that would lead to a "divide odd
integer by 2" scenario ever manifest.
- Defined bli_is_odd(), _is_even() macros in bli_scalar_macro_defs.h.

Added initial support for imaginary stride.
Details:
- Added an imaginary stride field ("is") to obj_t.
- Renamed bli_obj_set_incs() macro to bli_obj_set_strides().
- Defined bli_obj_imag_stride() and bli_obj_set_imag_stride() and
added invocations in key locations.
- Added some basic error-checking related to imaginary stride.
- For now, imaginary stride will not be exposed into the most-used
BLIS APIs such as bli_obj_create(), and certainly not the
computational APIs such as bli_dgemm().

Date: Sun Feb 8 19:40:34 2015 -0600
Defined gemm cntl function to query ukrs func_t.
Details:
- Added a new function, bli_gemm_cntl_ukrs(), that returns the func_t*
for the gemm micro-kernels from the leaf node of the control tree.
This allows all the func_t* fields from higher-level nodes in the tree
to be NULL, which makes the function that builds the control trees
slightly easier to read.
- Call bli_gemm_cntl_ukrs() instead of the cntl_gemm_ukrs() macro in
all bli_*_front() functions (which is needed to apply the row/column
preference optimization).
- In all level-3 bli_*_cntl_init() functions, changed the _obj_create()
function arguments corresponding to the gemm_ukrs fields in higher-
level cntl tree nodes to NULL.
- Removed some old her2k macro-kernels.

Added basic flop-counting mechanism (level-3 only).
Details:
- Added optional flop counting to all level-3 front-ends, which is
enabled via BLIS_ENABLE_FLOP_COUNT. The flop count can be
reset at any time via bli_flop_count_reset() and queried via
bli_flop_count(). Caveats:
- flop counts are approximate for her[2]k, syr[2]k, trmm, and
trsm operations;
- flop counts ignore extra flops due to non-unit alpha;
- flop counts do not account for situations where beta is zero.

Added 4m_1b implementation for gemm.
Details:
- Added yet another 4m-based implementation for complex domain level-3
operations. This method, which the 3m/4m paper identifies as Algorithm
"4m_1b" fissures the first loop around the micro-kernel so that the
real sub-panel of the current micro-panel of B is multiplied against
(both sub-panels of) all micro-panels of A, before doing the same for
the imaginary sub-panel of the micro-panel of B. For now, only gemm is
supported, and 4m_1b (labeled "4mb" within the framework) is not yet
integrated into the test suite.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Dec 9 16:03:14 2014 -0600
Fixed obscure level-2 packing / general stride bug.
Details:
- Fixed a bug in certain structured level-2 operations that manifested
only when the structured matrix was provided to BLIS as matrix stored
with general stride. The bug was introduced in c472993b when the
densify field was removed from the packm control tree node and
associated APIs. Since then, the packed object was unconditionally
marked with an uplo field of BLIS_DENSE. This is fine for level-3
operations where micro-panels are always densified, but in level-2
contexts, the underlying unblocked variant (fused or unfused) of
structured operations (e.g. trmv) still needs to know whether to
execute its "lower" or "upper" branches of code. Since this field
was unconditionally being set to BLIS_DENSE, the unblocked variants
were always executed the "else" branch, which happened to be the
"lower" case code. Thus, running an upper case produced the wrong
answer. This most obviously manifested in the form of failures for
trmm, trmm3, and trsm in the test suite.
The bug was fixed by setting the packed object's uplo field to
BLIS_DENSE only if the schema indicated that micro-panels were to be
packed. Otherwise, we can assume we are packing to regular row or
column storage, as is the case with level-2 packing. Thanks to
Francisco Igual for reporting the testsuite failures and ultimately
leading us to this bug.

eliminates redundant code and will allow any future tweaks to the

Relaxed constraint that KC be multiple of MR, NR.
Details:
- Relaxed a long-held requirement in register blocksizes that required
the kernel programmer to choose a KC that was divisible by both MR
and NR. This was very constraining on some architectures that did not
use register blocksizes that were powers of two. The constraint is
now enforced only for trmm and trsm, where it is needed, and it is
now handled by "nudging" kc upward at runtime, if necessary, to be a
multiple of MR or NR, as needed.
- Defined bli_trmm_determine_kc_[fb]() and bli_trsm_determine_kc_[fb](),
which determine blocksizes for trmm and trsm, taking special care to
"nudge" the kc dimension up to a multiple of MR or NR, as needed.
- Changed bli_trmm_blk_var3[fb].c to call bli_trmm_determine_kc_[fb]()
instead of bli_determine_blocksize_[fb]().
- Added safeguard to bli_align_dim_to_mult() that returns the dimension
unmodified if the dimension multiple is zero (to avoid division by
zero).
- Removed cpp guard/check for KC % MR == 0 and KC % NR == 0 from
bli_kernel_macro_defs.h.
- Whitespace, variable name changes to bli_blocksize.c.
- Removed old commented code from bli_gemm_cntl.c.

Re-implemented micro-panel alignment.
Details:
- This commit re-implements a feature that was removed in commit
c2b2ab62. It was removed because, at the time, I wasn't sure how the
micro-panel alignment feature would interact with the 4m method (when
applied at the micro-kernrel level), and so it seemed safer to disable
the feature entirely rather than allow possible breakage. This commit
revisits the issue and safely re-implements the feature in a way that
is compatible with 4m, 3m, 4mh, and 3mh (and native execution).
- Modified the static memory pool to account for micro-panel alignment
space.
- Modified packm_init and blocked variants to align whole micro-panels
by a datatype-specific alignment value that may be set by the
configuration. (If it is not set by the configuration, it will default
to BLIS_SIZEOF_?.)
- Modified macro-kernels so that:
- storage stride is handled properly given the new micro-panel
alignment behavior;
- indexing through 3m/4m/rih-type sub-panels, as is done by trmm and
trsm, is more robust (e.g. will work if the applicable packing
register blocksize is odd);
- imaginary strides are computed and stored within auxinfo_t structs,
which allows the virtual micro-kernels to more easily determine how
to index into the micro-panel operands.
- Modified virtual 3m and 4m micro-kernels to use the imaginary strides
within the auxinfo_t structs instead of panel strides.
- Deprecated the panel stride fields from the auxinfo_t structs.
- Updated test suite to print out the micro-panel alignment values.

Minor changes and fixes.
Details:
- Redefined bli_is_last_iter() to take thread_id and num_thread
arguments, which allows the macro to correctly compute whether a
given iteration is the last that the thread will compute in that
particular loop. The new definition, however, remains disabled
(commented out) until someone can look at this more closely, as
the new definition seems to actually hurt performance slightly.
- Whitespace and related updates to level-3 macro-kernels.
- Updated test suite so that performance results in the hundreds of
gigaflops does not disrupt the column alignment of the output.

Fixed a bug in the pack schema-related bit macros.
Details:
- Expanded the BLIS_PACK_SCHEMA_BITS value in bli_type_defs.h to
include all six bits presently used in the pack schema bitfield of
the info field of obj_t structs. Prior to this commit, the macro
constant only included the lowest five bits, which excluded the
"is or is not packed" bit. This manifested as a strange bug in
probably many level-2 codes that invoked packing, though we only
observed it in ger before fixing. Thanks to Devin Matthews for
finding and reporting this bug.

Added high-level implementations of 4m, 3m.
Details:
- Added "4mh" and "3mh" APIs, which implement the 4m and 3m methods at
high levels, respectively. APIs for trmm and trsm were NOT added due
to the fact that these approaches are inherently incompatible with
implementing 4m or 3m at high levels (because the input right-hand
side matrix is overwritten).
- Added 4mh, 3mh virtual micro-kernels, and updated the existing 4m and
3m so that all are stylistically consistent.
- Added new "rih" packing kernels (both low-level and structure-aware)
to support both 4mh and 3mh.
- Defined new pack_t schemas to support real-only, imaginary-only, and
real+imaginary packing formats.
- Added various level0 scalar macros to support the rih packm kernels.
- Minor tweaks to trmm macro-kernels to facilitate 4mh and 3mh.
- Added the ability to enable/disable 4mh, 3m, and 3mh, and adjusted
level-3 front-ends to check enabledness of 3mh, 3m, 4mh, and 4m (in
that order) and execute the first one that is enabled, or the native
implementation if none are enabled.
- Added implementation query functions for each level-3 operation so
that the user can query a string that describes the implementation
that is currently enabled.
- Updated test suite to output implementation types for reach level-3
operation, as well as micro-kernel types for each of the five micro-
kernels.
- Renamed BLIS_ENABLE_?COMPLEX_VIA_4M macros to _ENABLE_VIRTUAL_?COMPLEX.
- Fixed an obscure bug when packing Hermitian matrices (regular packing
type) whereby the diagonal elements of the packed micro-panels could
get tainted if the source matrix's imaginary diagonal part contained
garbage.

Pass pack_t schemas into ukernels via auxinfo_t.
Details:
- Modified macro-kernels to pass the pack_t schema values for matrices
A and B into the datatype-specific functions, where they are now
inserted into a newly-expanded auxinfo_t struct. This gives gives the
micro-kernels access to the pack_t schema values embedded in the
control trees, which determine the precise format into which the
matrix elements are packed.
- Updated a call to bli_packm_init_pack() in src/test_libblis.c to
remove densify argument. Meant to include this in commit c472993b.

Removed densify argument to packm_cntl_obj_create().
Details:
- Removed the "densify" bool_t argument to bli_packm_cntl_obj_create().
This argument was inserted very early in BLIS's development, when it
was anticipated that the developer may sometimes wish to pack a
Hermitian, symmetric, or triangular matrix without making it dense.
But as it turns out, if we are packing a matrix, we always want to
make it dense in some way or another due to the fact that the micro-
kernel only multiplies dense micro-panels. Thus, unless/until there
is a real need for the feature, it seems reasonable to remove it from
the packm_cntl API.

Retired trmm_t control tree definitions, usage.
Details:
- Replaced all trmm_t control tree instances and usage with that of
gemm_t. This change is similar to the recent retirement of the herk_t
control tree.
- Tweaked packm blocked variants so that the triangular code does NOT
assume that k is a multiple of MR (when A is triangular) or NR (when
B is triangular). This means that bottom-right micro-panels packed for
trmm will have different zero-padding when k is not already a multiple
of the relevant register blocksize. While this creates a seemingly
arbitrary and unnecessary distinction between trmm and trsm packing,
it actually allows trmm to be handled with one control tree, instead
of one for left and one for right side cases. Furthermore, since only
one tree is required, it can now be handled by the gemm tree, and thus
the trmm control tree definitions can be disposed of entirely.
- Tweaked trmm macro-kernels so that they do NOT inflate k up to a
multiple of MR (when A is triangular) or NR (when B is triangular).
- Misc. tweaks and cleanups to bli_packm_struc_cxk_4m.c and _3m.c, some
of which are to facilitate above-mentioned changes whereby k is no
longer required to be a multiple of register blocksize when packing
triangular micro-panels.
- Adjusted trmm3 according to above changes.
- Retired trmm_t control tree creation/initialization functions.

Retired herk_t control tree definitions, usage.
Details:
- Replaced all herk_t control tree instances and usage with that of
gemm_t, since the two types presently have the same fields. This means
that herk, her2k, syrk, and syr2k can simply use the gemm control tree
as-is, just as hemm and symm have been doing for some time now.
- Retired herk_t control tree creation/initialization functions.
- Retired many _target.c and .h files into 'old' directories.

functions. This makes the code a little easier to read since "m" and
"n" have connotations that are not applicable here.

Retired portions of bli_kernel_3m/4m_macro_defs.h.
Details:
- Removed sections of bli_kernel_[4m|3m]_macro_defs.h that defined
4m/3m-specific blocksizes after realizing that this can be done in
bli_gemm[4m|3m]_cntl.c, since that is (mostly) the only place they
are used.
- The maximum cache values for 4m/3m are stll needed when computing mem
pool dimensions in bli_mem_pool_macro_defs.h. As a workaround, "local"
definitions in terms of the regular cache blocksizes are now in place.
- Similarly, the register blocksizes for 4m/3m are still needed in
bli_kernel_post_macro_defs.h. As a workaround, "local" definitions in
terms of the regular register blocksizes are now in place.

Changed semantics of blocksize extensions.
Details:
- Changed semantics of cache and register blocksize extensions so that
the extended values are tracked, rather than just the marginal
extensions.
- BLIS_EXTEND_[MKN]C_? has been renamed BLIS_MAXIMUM_[MKN]C_?.
- BLIS_EXTEND_[MKN]R_? has been renamed BLIS_PACKDIM_[MKN]R_?.
- bli_blksz_ext_*() APIs have been renamed to bli_blksz_max_*(). Note
that these "max" query routines grab the maximum value for cache
blocksizes and the packdim value for register blocksizes.
- bli_info_*() API has been updated accordingly.
- All configurations have been updated accordingly.

- Changed the interface to the packm_struc_cxk*() kernels to include
the pack_t schema. This allows the implementation to more easily

or column-stored row panel).
- Updated packm blocked variants to pass in the schema.
- Updated packm_ker_t function pointer definition accordingly.

Reorganized packm implementation.
Details:

routines for a given pack format (4m, 3m, regular) reside in a single
file.
- Renamed _blk_var4 to _blk_var2 and generalized so that it will work
for
both 4m and 3m, and adjusted 4m/3m _cntl_init() functions accordingly.
- Added a new packm_ker_t function pointer type to
bli_kernel_type_defs.h
to facilitate function pointer typecasting in the datatype-specific
packm_blk_var2() functions.
- Deprecated _blk_var3.
- Fixed a bug in the triangular micro-panel packing facility that
affected trmm and trmm3 with unit diagonals.

Renamed packm scalar from beta to kappa.
Details:
- The packm implementation (i.e. sources files in frame/1m/packm and
frame/1m/packm/ukernels), interchangeably used the names "beta" and
"kappa" to refer to the optional scalar to be applied during packing.
This commit renames all uses of "beta" to be "kappa", since "beta"
sometimes evokes the scalar specifically on the output matrix of a
level-2 or level-3 operation.

Cleaned up front-end layering for 4m/3m.
Details:
- Added an extra layer to level-3 front-ends (examples: bli_gemm_entry()
and bli_gemm4m_entry()) to hide the control trees from the code that
decides whether to execute native or 4m-based implementations. The
layering was also applied to 3m.
- Branch to 4m code based on the return value of bli_4m_is_enabled(),
rather than the cpp macros BLIS_ENABLE_?COMPLEX_VIA_4M. This lays
the groundwork for users to be able to change at runtime which
implementation is called by the main front-ends (e.g. bli_gemm()).
- Retired some experimental gemm code that hadn't been touched in
months.

Added bli_4m API for querying 4m enabled state.
Details:
- Added bli_4m.c (and header), which defines a simple API that can be
used to query, enable, and disable 4m-based complex support in BLIS.
The macros BLIS_ENABLE_?COMPLEX_VIA_4M are now used to initialize
the variable that determines the state (enabled or disabled).
- Changed bli_info*() API so that all cache and register blocksize-
related query routines return the blksz_t objects' values as they
exist at runtime, rather than return the values as determined by the
configuration system (e.g. bli_kernel.h, or defaults for those values
not specified). This sets the foundation for being able to change
those blocksizes at runtime.

Minor update to sandybridge MC_S, KC_S.
Details:
- Changed sandybridge MC and KC for single-precision real to 128 and 384,
respectively.
- Updated comments in template configuration's gemm micro-kernel file
to document the new "contiguous row preference" macro.

Author: Field G. Van Zee <field@cs.utexas.edu>

Added optional row preference to ukernel config.
Details:
- Added the ability for the kernel developer to indicate the gemm micro-
kernel as having a preference for accessing the micro-tile of C via
contiguous rows (as opposed to contiguous columns). This property may
be encoded in bli_kernel.h as BLIS_?GEMM_UKERNEL_PREFERS_CONTIG_ROWS,
which may be defined or left undefined. Leaving it undefined leads to
the default assumption of column preference.
- Changed conditionals in frame/3/*/*_front.c that induce transposition
of the operation so that the transposition is induced only if there
is disagreement between the storage of C and the preference of the
micro-kernel. Previously, the only conditional that needed to be met
was that C was row-stored, which is to say that we assumed the micro-
kernel preferred column-contiguous access on C.
- Added a "prefers_contig_rows" property to func_t objects, and updated
calls to bli_func_obj_create() in _cntl.c files in order to support
the above changes.
- Removed the row-storage optimization from bli_trsm_front.c because
it is actually ineffective. This is because the right-side case of
trsm flips the A and B micro-panel operands (since BLIS only requires
left-side gemmtrsm/trsm kernels), meaning any transposition done
at the high level is then undone at the low level.
- Tweaked trmm, trmm3 _front.c files to eliminate a possible redundant
invocation of the bli_obj_swap() macro.

Reorganized packm ukernels.
Details:
- Previously, packm micro-kernels were organized by the implied register
blocksize (panel dimension) assumed by the kernel, meaning conventional,
ri, and ri3 variations of some micro-kernel size were housed in the same
file. This commit reorganizes the micro-kernels so that all sizes reside
in the same file for each format type (conventional, ri, and ri3).

Tweaks to gemm4m, gemm3m virtual ukernels.
Details:
- Fixed a potential, but as-yet unobserved bug in gemm3m that would
allow undesirable inf/NaN propogation, since C was being scaled by
beta even if it was equal to zero.
- In gemm3m micro-kernel, we now avoid copying C to the temporary
micro-tile if beta is zero.
- Rearranged computation in gemm4m so that the temporary C micro-tile
is accessed less, and C is accessed only after the micro-kernel
calls. This improves performance marginally in most situations.
- Comment updates to both gemm4m and gemm3m micro-kernels.

Reverted _obj_is_[row|col]_stored() macros.
Details:
- Rolled back recent changes to bli_obj_is_row_stored() and
bli_obj_is_col_stored() so that those macros now only inspect the
strides (row or column). It turns out that the more sophisticated
definitions introduced in a51e32e are not necessary, because these
"obj" macros are virtually never used on packed matrices, and when
they are, they can use bli_obj_is_[row|col}_packed() macros, which
inspect the info bitfield.

little easier to read.

Date: Mon Aug 4 15:49:59 2014 -0500
Added CBLAS compatibility layer.
Details:
- Added a new section in bli_config.h files of all configurations for
enabling CBLAS support. (Currently, the default is for the CBLAS layer
to be disabled.)
- Added a directory, frame/compat/cblas, to house CBLAS source code. A
subdirectory 'f77_sub' holds subroutine wrappers corresponding to
subroutines found in CBLAS that allow calling some BLAS routines with
the return value passed as the last argument rather than as an actual
(function) return value. This was probably intended to allow CBLAS to
avoid the whole f2c debacle altogether. However, since BLIS does not
assume the presence of a Fortran compiler, we had to provide similar
routines in C.
- A script, integrate-cblas-tarball.sh, is included to streamline the
integration of future revisions of the CBLAS source code.
- The current tarball, cblas.tgz, that was used with the above script to
generate the present set of CBLAS source code is also included.
- Updated blis.h to include necessary CBLAS-related headers.

Fix permissions error installing to non-owned directory
commit db97ce979b88c051922c2f946ce52d523c7a12c6
Author: Kevin Locke <kevin@kevinlocke.name>
Date: Sun Aug 3 12:48:04 2014 -0600
Fix permissions error installing to non-owned directory
When installing to a directory which is not owned by the installing
user, even when the user has write permission for the directory, the
installation can fail with an error similar to the following:
Installing libblis-0.1.4-7-sandybridge.a into /usr/local/lib/
install: cannot change permissions of ‘/usr/local/lib’: Operation not permitted
Makefile:658: recipe for target '/usr/local/lib/libblis-0.1.4-7-sandybridge.a' failed
make: *** [/usr/local/lib/libblis-0.1.4-7-sandybridge.a] Error 1
In the example case, the error occurred because the user attempted to
install to /usr/local and /usr/local/lib is owned by root with mode 2755
which the Makefile unsuccessfully attempted to change to 0755.
Given that installing to /usr/local is likely to be quite common and the
ownership/permissions are the default for Debian and Debian-derived
Linux distributions (perhaps others as well), this commit attempts to
support that use case by using mkdir rather than install to create the
directory (which is the same approach as Automake).

Redefined bit field macros with bitshift operator.
Details:
- Redefined many of the macros that define bit fields and bit values in
the obj_t info field using the bitshift operator (<<). This makes it
easier to reorder bit fields, or expand existing bit fields, or add
new fields. The bitshifting should be evaluated by the compiler at
compile-time.

Reimplemented unit blocksize fix in prev commit.
Details:
- Instead of inferring the storage format of the micro-panels from within
the packm variants, we now pass in a bool_t value that denotes whether
the packed matrix contains row-stored column panels or column-stored
row panels. This value can then be tested more easily inside the main
packm variant loop.
- Renumbered pack_t schema values in bli_type_defs.h so that there are
now five bits, each with different meaning:
- 4: packed or not packed?
- 3: packed for 3m?
- 2: packed for 4m?
- 1: packed to panels?
- 0: stored by rows or columns?
- Added new macros that test for status of above bits in schema bit
subfield, and renamed some existing macros related to 4m/3m.

Fixed unit register blocksize brokenness.
Details:
- Fixed a breakdown in BLIS's ability to differentiate between row-stored
and column-stored micro-panels when MR or NR is unit. When either
register blocksize (or both) is equal to one, inspecting the strides of
the affected packed micro-panel is no longer sufficient to determine
whether the micro-panel is a row-stored column panel or a column-stored
row panel (because both strides are unit). At that point, dimension
information is necessary when invoking the bli_is_row_stored_f() and
bli_is_col_stored_f() macros (and their "obj" counterparts). Thanks to
Ilya Polkovnichenko for reporting this bug.
- Added panel dimensions (m and n) to obj_t, which are set in
packm_init() and then passed into the blocked variants to support the
aforementioned update.

Tweaked behavior of herk, her2k for BLAS compat.
Details:
- Updated herk_front() and her2k_front() to explicitly set the imaginary
components of the diagonal entries of C to zero after the computation
is complete. This is needed in case downstream applications read the
full diagonal entries (i.e., including imaginary part), which could, in
the absence of this modification, accumulate numerical error from
subsequent rank-k/rank-2k updates.
- Updated BLAS compatibility wrappers for herk and her2k to return early
if:
n == 0 || ( ( alpha == 0 || k == 0 ) && beta == 1 )
This also results in the imaginary components of diagonal entries NOT
being set to zero (see above), which is consistent with BLAS.
- Updated mkherm to use setid instead of an inlined loop over the
diagonal.

matrix real-valued.

Changed order of zero dim / error checking.
Details:
- Updated level-2 and level-3 internal back-ends so that the operation's
_check() function is called BEFORE any attempt to return early due to
the presence of zero dimensions. This ordering makes more sense because
(for example) object dimensions should match even if one of them is
zero. Previously, a dimension mismatch could result in an early return
with no error message.
- Updated bli_check_object_buffer() so that NULL buffers result in an
error only if the object is dimensionally non-empty (i.e., only if both
of the object's dimensions are non-zero). This allows BLIS operations
to be performed on dimensionally empty objects (i.e., where at least one
dimension is zero).
- Updated the error message associated with bli_check_object_buffer()
to mention the newly relaxed constraint mentioned above, vis-a-vis
non-zero dimensions.

Date: Sun Jul 13 17:38:33 2014 -0500
Implemented dsdot() and sdsdot() in compat layer.
Details:
- Replaced "not yet implemented" error messages in dsdot() and sdsdot()
with actual implementations. (These routines are so rarely used that
this log message will probably lead to some people learning of their
existence for the first time.)
commit 255668ddd1004552c6cc65035ec6486671ce99bb
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Jul 13 17:30:44 2014 -0500
Inserted gemv beta-scaling bug into compat layer.
Details:
- BLAS has a peculiar bug (or feature) whereby calling gemv on a vector
y of non-zero length and a vector x of zero length results in no action.
Given that the operation is y := beta*y + A*x, many (most?) individuals
would expect vector y to still be scaled by beta. BLIS, when called
natively, handles these cases intuitively (with beta scaling).
Unfortunately, many BLAS test suites actually check for the way this
situation is handled. Therefore, we have decided to implement this "bug"
in the compatibility layer so as to provide "bug-for-bug" compatibility
with BLAS.

commit 26cd81990631ff799791629206e068126ff9e3a1
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Jul 10 13:16:07 2014 -0500
Added bli_info_*() query functions.
Details:
- Added a new API family, bli_info_*(), which can be used to query
information about how BLIS was configured. Most of these values are
returned as gint_t, with the exception of the version string which
is char*.
- Changed how the testsuite driver queries information about how BLIS
was configured (from using macro constants directly to using the
new bli_info API).
- Removed bli_version.c and its header file.
- Added STRINGIFY_INT() macro to bli_macro_defs.h
- Renamed info_t type in bli_type_defs.h to objbits_t (not because of
an actual naming conflict, but because the name 'info_t' would now be
somewhat misleading in the presence of the new bli_info API, as the
two are unrelated).

Minor bugfixes to BLAS compatibility layer.
Details:
- Changed bla_amax.c so that i?amax() routines now correctly return 0
if ( n < 1 || incx <= 0 ).
- Changed bla_rotg.c and bla_rotmg.c to use bli_fabs() macro instead of
f2c's abs() macro for float and double cases.
- Thanks to Murtaza Ali for suggesting the two fixes above.
- Updated label of fnormv to normfv in testsuite/input.operations.

Fixed possible level-3 inf/NaN issue when beta=0.
Details:
- Redefined xpbys_mxn and xpbys_mxn_u/_l macros to employ a copy
(instead of scaling by beta) when beta is zero. This will stamp out
any possible infs or NaNs in the output matrix, if it happens to be
uninitialized. Thanks to Tony Kelman for isolating this bug.

Date: Thu Jul 3 11:48:23 2014 -0500
Defined _ukernel_void() wrappers to micro-kernels.
Details:
- Added wrappers for micro-kernels so that users may invoke the
micro-kernels without knowing what the function names actually are.
This is useful when an application wishes to call the micro-kernel
from a shared library instance of BLIS, where the application may not
necessarily have the luxury of grabbing the micro-kernel name(s) from
C preprocessor macros at compile-time. Also, since the wrappers use
void* pointers, one's environment does not need to be aware of some
BLIS types such as scomplex and dcomplex. These wrappers now join the
level-1 and level-1f kernel wrappers, which pre-dated this commit.
- Removed the wrapper definitions and prototypes from the micro-kernel
test suite modules, and replaced calls to them with calls to the new
wrappers mentioned above.

Quick and dirty multithreading for TRSM
Should work fine for small number of threads (up to 8 or maybe even 16).
However, performance is yet untested.
This parallelizes the "JR" loop for the left sided cases
and the "IR" loop for the right sided cases.
Future work is to parallelize the outer loops as well.

Added shared library support to build system.
Details:
- Modified top-level Makefile to support building shared (dynamic)
libraries.
- Updated most configurations' make_defs.mk files to include necessary
compiler/linker flags needed by top-level Makefile.
- Note that by default, all configurations presently do NOT build
shared libraries. To enable, one must change the value of
BLIS_ENABLE_DYNAMIC_BUILD to 'yes'.

Fixed ldim alignment bug in core2 gemm ukernel.
Details:
- Fixed a bug in the dunnington/core2 gemm micro-kernels that resulted in
a segmentation fault if a column-stored matrix's starting address was
aligned, but its leading dimension was such that its second column was
unaligned. Basically, the micro-kernel was assuming that aligned load
instructions were safe when they actually were not. An extra condition
that checks the alignment of cs_c (ie: the leading dimension in the
column storage case) has now been added. Thanks to Michael Lehn for
reporting this bug.

Changed treatment of NULL object buffers.
Details:
- Relaxed the constraint in bli_obj_attach_buffer_check(), which required
the buffer address being attached to be non-NULL. This is acceptable
because the user was already able to create and use objects with NULL
buffers (via bli_obj_create_without_buffer(), which initializes the
buffer to NULL).
- Inserted calls to newly defined function, bli_check_object_buffer(),
into nearly all operations' _check() or _int_check() functions. This
allows BLIS to abort peacefully if a computational routine is called
with an object containing a NULL buffer. By contrast, under such
conditions, BLAS would typically fail with a segmentation fault.
- Within operation front-ends, moved the calls to _check()/_int_check()
so that zero dimensions are checked first (and if found, execution
returns with trivial or no computation). This resolves issue #7. Thanks
to Jack Poulson for reporting this bug.

Can now query register blocksizes from blk algs.
Details:
- Added a new field to blksz_t objects that allows one to attach a
sub-object. Doing this allows us to associate a register blocksize with
any given cache blocksize. That way, the register blocksize can be
queried wherever the cache blocksize would normally be accessible
(e.g. a blocked algorithm).
- Modified bli_gemm_cntl.c (and 4m/3m variants) so that the register
blocksizes are attached to the cache blocksizes after they are created.

Fixed issue #6 (incorrect 'restrict' usage).
Details:
- Fixed improper usage of restrict keyword in axpyv and dotv bgq kernels.
(However, there may be other instances of similar misuse elsewhere in
BLIS.) Thanks to Jeff Hammond for reporting this issue.

but not the outer packing routines.
This allowed, for instance, the block of B to not be finished being packed before computation to occur.

Refined INSERT_GENTFUNC macro usage.
Details:
- Defined new INSERT_GENTFUNC macros so that the macro always takes
exactly the number of arguments needed for the particular operation or
variant being defined. Many operations were using INSERT_GENTFUNC
macros that expected one auxiliary argument even though none were
needed. Those instances have now been updated. Most of these instances
were in the level-0 and -1v operations, as well as some operations
defined in frame/util.

Minor simplifications to trmm, trsm macro-kernels.
Details:
- Simplified some code that would have allowed the diagonal of a trmm
or trsm triangular matrix to intersect the short end of a micro-panel.
This is disallowed via higher-level constraints on cache blocksizes, so
this code was never needed and only served to obfuscate.
- Updated some comments in trmm, trsm macro-kernels.

Reorganized norm operations.
Details:
- Completely reoganized norm operations:
- Renames:
- fnormsc, fnormv, fnormm -> normfsc, normfv, normfm (2-norm)
- absumv -> norm1v (vector 1-norm)
- New operations:
- norm1m (matrix 1-norm)
- normiv, normim (infinity-norm)
- amaxv (BLAS-like absolute maximum value index)
- asumv (BLAS-like absolute sum)
- Deprecated absumm, as it did not correspond to any actual norm.
(However, an inlined version now exists in the testsuite module for
randm.)

Minor fixes to sumsqv, abmaxv.
Details:
- Minor update to bli_sumsqv_unb_var1() to bring it up-to-date with
LAPACK 3.5.0's zlassq.f, which, starting with 3.4.2, returns NaN when
the vector (or matrix) contains a NaN.
- Minor change to bli_abmaxv_unb_var1() to more closely mimic the
behavior of netlib BLAS's izamax(). There, a "less than or equal to"
operator is used in the search instead of "less than", which would
change the element index returned if there were multiple maximum values.
- Added macro function definitions for bli_isinf() and bli_isnan(), which
are currently implemented in terms of isinf() and isnan() from math.h.

Fixed various bugs when C99 complex is enabled.
Details:
- Fixed various bugs in packm_*_cxk(), the 4m/3m micro-kernels, and
elsewhere in the framework that were not yet set up to work properly
when BLIS_ENABLE_C99_COMPLEX is defined in bli_config.h
- Extensive changes to f2c-derived files in frame/compat/f2c to allow
C99 complex storage. Most of these changes center around accessing
real and imaginary components via bli_?real()/bli_?imag() accessor
macros, and setting of values via bli_?sets() assignment macros.
(Thanks to Vladimir Sukarev for pointing out that _ENABLE_C99_COMPLEX
was broken.)

Fixed bug with parallel packing, and bug with allocating an array of thread infos

This dependeny was removed, allowing each iteration to be executed in parallel.

Deprecated panel stride alignment in bli_config.h.
Details:
- Removed BLIS_CONTIG_STRIDE_ALIGN_SIZE from bli_config.h of all
configurations. It was already going unused in packm_init() since the
recent 4m/3m commit. This setting was rarely, if ever, useful, and its
existence only posed a potential risk for 4m/3m-based implementations.
- Removed BLIS_CONTIG_STRIDE_ALIGN_SIZE usage from mem_pool_macro_defs.h.
- Updated comments regarding CONTIG_STRIDE_ALIGN_SIZE in template
micro-kernels.

CHANGELOG update (for 0.1.1).
commit fde5f1fdece19881f50b142e8611b772a647e6d2 (tag: 0.1.1)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 25 13:34:56 2014 -0600
Added extensive support for configuration defaults.
Details:
- Standard names for reference kernels (levels-1v, -1f and 3) are now
macro constants. Examples:
BLIS_SAXPYV_KERNEL_REF
BLIS_DDOTXF_KERNEL_REF
BLIS_ZGEMM_UKERNEL_REF
- Developers no longer have to name all datatype instances of a kernel
with a common base name; [sdcz] datatype flavors of each kernel or
micro-kernel (level-1v, -1f, or 3) may now be named independently.
This means you can now, if you wish, encode the datatype-specific
register blocksizes in the name of the micro-kernel functions.
- Any datatype instances of any kernel (1v, 1f, or 3) that is left
undefined in bli_kernel.h will default to the corresponding reference
implementation. For example, if BLIS_DGEMM_UKERNEL is left undefined,
it will be defined to be BLIS_DGEMM_UKERNEL_REF.
- Developers no longer need to name level-1v/-1f kernels with multiple
datatype chars to match the number of types the kernel WOULD take in
a mixed type environment, as in bli_dddaxpyv_opt(). Now, one char is
sufficient, as in bli_daxpyv_opt().
- There is no longer a need to define an obj_t wrapper to go along with
your level-1v/-1f kernels. The framework now prvides a _kernel()
function which serves as the obj_t wrapper for whatever kernels are
specified (or defaulted to) via bli_kernel.h
- Developers no longer need to prototype their kernels, and thus no
longer need to include any prototyping headers from within
bli_kernel.h. The framework now generates kernel prototypes, with the
proper type signature, based on the kernel names defined (or defaulted
to) via bli_kernel.h.
- If the complex datatype x (of [cz]) implementation of the gemm micro-
kernel is left undefined by bli_kernel.h, but its same-precision real
domain equivalent IS defined, BLIS will use a 4m-based implementation
for the datatype x implementations of all level-3 operations, using
only the real gemm micro-kernel.

commit 6363a9f658257fe3d814a3dce5308f807adb54a2
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 19 17:00:52 2014 -0600
Added level-3 support for complex via 4m-/3m.
Details:
- Added the ability to induce complex domain level-3 operations via new
virtual complex micro-kernels which are implemented via only real
domain micro-kernels. Two new implementations are provided: 4m and 3m.
4m implements complex matrix multiplication in terms of four real
matrix multiplications, where as 3m uses only three and thus is
capable of even higher (than peak) performance. However, the 3m method
has somewhat weaker numerical properties, making it less desirable
in general.
- Further refined packing routines, which were recently revamped, and
added packing functionality for 4m and 3m.
- Some modifications to trmm and trsm macro-kernels to facilitate indexing
into micro-panels which were packed for 4m/3m virtual kernels.
- Added 4m and 3m interfaces for each level-3 operation.
- Various other minor changes to facilitate 4m/3m methods.

Minor fixes to trsm consistent with prev on trmm.
Details:
- Removed use of bli_min() and bli_max() that were only being used to
try to support situations where the diagonal would intersect the
short end of some micro-panels, which is situation that is disallowed
at a higher level by various constraints on the register and cache
blocksize. This only affected trsm_ll and trsm_lu.
- Use panel stride as passed into the macro-kernel rather than compute
it via k and PACKMR/PACKNR. This affects all macro-kernels of trsm.

Fixed obscure bug in trmm_ll, trmm_lu.
Details:
- Fixed an obscure bug in left-hand trmm that would only manifest when
non-zero register blocksize extensions (PACKMR > MR or PACKNR > NR)
are used.
- Removed use of bli_min() and bli_max() that were only being used to
try to support situations where the diagonal would intersect the
short end of some micro-panels, which is situation that is disallowed
at a higher level by various constraints on the register and cache
blocksize. This only affected trmm_ll and trmm_lu.
- Use panel stride as passed into the macro-kernel rather than compute
it via k and PACKMR/PACKNR. This affects all macro-kernels of trmm.

Fixed an obscure bug in packm_cxk().
Details:
- Fixed a bug in packm_cxk() whereby the packm ukernel was being chosen
from ldp, which is always equal to PACKMR or PACKNR. The problem with
this is that the pack ukernels were implicitly assuming that the
panel dimension of the panel being packed was equal to ldp, which
is not the case when the register blocksizes extensions are non-zero
(ie: when PACKMR > MR or PACKNR > NR, whichever is applicable). This
problem has been fixed by passing ldp into the pack ukernels, which
now walk through the packed micro-panel region by incrementing by this
value, rather than incrementing by the inherent panel dimension value
assumed by each packm ukernel (e.g. 4 in the case of packm_ref_4xk).
- Also fixed a very minor edge case inefficiency whereby pack ukernels
smaller than the default were not being used in edge cases, and instead
those situations were being handled by scal2m. This is related to the
issue above, because the pack ukernel itself was being chosen based on
ldp instead of the panel dimension.

Consolidated packm_blk_var2 and var3.
Details:
- Consolidated the functionality previously supported by packm_blk_var2()
and packm_blk_var3() into a new variant, packm_blk_var1().
- Updates to packm_gen_cxk(), packm_herm_cxk.c(), and packm_tri_cxk()
to accommodate above changes.
- Removed packm_blk_var3() and retired packm_blk_var2() to
frame/1m/packm/old.
- Updated all level-3 _cntl_init() functions so that the new, more
versatile packm_blk_var1 is used for all level-3 matrix packing.

Refactored packm variants.
Details:
- Revised packm_blk_var2() and _var3() by encapsulating the general,
hermitian/symmetric, and triangular panel-packing subproblems into
separate functions: packm_gen_cxk(), packm_herm_cxk(), and
packm_tri_cxk(), respectively. Also, homogenized the packm code as
well as the new specialized packm_*_cxk() code to further improve
readability.

Employ simpler INSERT_ macro for ref ukernels.
Details:
- Defined a new macro, INSERT_GENTFUNC_BASIC0, which takes only one
argument--the base name of the function--and employed this macro
in the reference micro-kernel files instead of the _BASIC macro,
which takes one auxiliary argument. That argument was not being
used and probably just acted to unnecessarily obfuscate.

keyword in the reference trsm micro-kernels.
- Tweak to testsuite/Makefile that causes rebuild if libblis was
touched.

Updated comments in macro-kernels.
Details:
- Updated (and fixed some errors in) the "Assumptions/assertions" comment
section of macro-kernels.
- Changed register blocksizes of reference configuration to MR = 8 and
NR = 4. It's always good for MR != NR in the reference configuration
since it may help uncover bugs related to non-square micro-kernels.

Pass panel dimensions into macro-kernels.
Details:
- Modified the interfaces to the datatype-specific macro-kernels so that:
- pd_a and pd_b are passed in (which contain the panel dimensions of
packed panels of a and b).
- rs_a and cs_b are no longer passed in (they were guaranteed to be 1).
- Modified implementations of datatype-specific macro-kernels so pd_a,
pd_b, cs_a, and rs_b are used instead of cpp macros for MR, NR, PACKMR,
and PACKNR, respectively.
- Declare temporary c matrices (ct) as being maxmr-by-maxnr, which for now
is equivalent to being mr-by-nr. maxmr and maxnr are declared in a new
header file bli_kernel_post_macro_defs.h.

Deprecated incremental blocksize macro const defs.
Details:

from all configurations' bli_kernel.h files. This change is minor and
is mostly a cleanup related to a previous commit.

Added early returns for "object is zeros" case.
Details:
- Added some logic to packm_init(), pack_int() and gemm_int() so that
(a) objects marked as BLIS_ZEROS are not packed, and (b) those
objects are not computed with. This functionality is not currently
needed by any existing implementations, but may be used in the
future.

Added 'f' on some gemm and trmm blocked variants.
Details:
- Added 'f' to some block variant files/functions to be consistent with
other file/functions' naming convention. Here, the f indicates
partitioning in the "forward" direction.

Removed redundant non-gemm blksz_t creation.
Details:
- Removed code that creates duplicate blksz_t objects for herk, trmm,
and trsm. Instead, the gemm blksz_t objects are accessed via extern
and used directly. This reduces the amount of code associated with
each of the three _cntl_init() and _cntl_finalize() function.

Introduced new level-3 front-end layer.
Details:
- Added new _front() functions for each level-3 operation. This is done
so that the choosing of the control tree (and *only* the choosing of
the control tree) happens in what was previously the "front end"
(e.g. bli_gemm()). That control tree is then passed into the _front()
function, which then performs up-front tasks such as parameter
checking.

Removed redundant hemm, her2k control trees.
Details:
- Removed code that generated a control tree specifically for hemm and
symm. Instead, the gemm control tree is now configured so that it
works for gemm, hemm, or symm.
- Retired most her2k code, as it was not being used. (Currently, her2k is
implemented as two invocations of herk.) I couldn't think of many
situations where her2k variants were needed.
- Removed some older her2k code.

Embed func_t microkernel objects in control trees.
Details:
- Modified all control tree node definitions to include a new field of
type func_t*, which is similar to a blksz_t except that it contains
one function pointer (each typed simply as void*) for each datatype.
We use the func_t* to embed pointers to the micro-kernels to use for
the leaf-level nodes of each control tree. This change is a natural
extension of control trees and will allow more flexibility in the
future.
- Modified all macro-kernel wrappers to obtain the micro-kernel pointers
from the incomming (previously ignored) control tree node and then pass
the queried pointer into the datatype-specific macro-kernel code, which
then casts the pointer to the appropriate type (new typedefs residing
in bli_kernel_type_defs.h) and then uses the pointer to call the micro-
kernel. Thus, the micro-kernel function is no longer "hard-coded" (that
is, determined when the datatype-specific macro-kernel functions are
instantiated by the C preprocessor).
- Added macros to bli_kernel_macro_defs.h that build datatype-specific
base names if they do not exist already, and then uses those to build
datatype-specific micro-kernel function names. This will allow
developers extra flexibility if they wanted to, for example, name each
of their datatype-specific micro-kernels differently (e.g. double
real might be named bli_dgemm_opt_4x4() while double complex might be
named bli_zgemm_opt_2x2()).
- Inserted appropriate code into _cntl_init() functions that allocates
and initializes a func_t object for the corresponding micro-kernels.
The gemm ukernel func_t object is created once, in bli_gemm_cntl_init(),
and then reused via extern wherever possible.

Removed commented mixed domain macro-kernel code.
Details:
- Removed commented-out code from macro-kernels that was supposed to
facilitate implementing mixed domain (complex times real) matrix
multiplication. This functionality is still (probably possible),
but I'm getting tired of looking at the code every time I edit
a macro-kernel. Plus, there are probably ways of doing it at a
higher level, via control trees.

Removed b_aux field from cntl nodes.
Details:
- Removed b_aux field from all control tree node definitions. This field
was being used in certain optimizations (incremental blocking) that were
not actually being employed within BLIS, and are probably not employed
by others.
- Updated all _cntl_obj_create() function definitions and invocations
according to above change.
- Retired bli_gemm_blk_var4.c, which was one such function that employed
incremental blocking, but which was never called by BLIS itself.

Consolidated pack_t enums; retired VECTOR value.
Details:
- Changed the pack_t enumerations so that BLIS_PACKED_VECTOR no longer has
its own value, and instead simply aliases to BLIS_PACKED_UNSPEC. This
makes room in the three pack_t bits of the info field of obj_t so that
two values are now unused, and may be used for other future purposes.
- Updated sloppy terminology usage in comments in level-2 front-ends.
(Replaced "is contiguous" with more accurate "has unit stride".)

Suppress warning in Makefile (UNINSTALL_LIBS).
Details:
- Redirect errors to /dev/null when using 'find' to locate libraries that
would be uninstalled upon executing "make uninstall-old". Before, if the
Makefile was read before $(INSTALL_PREFIX)/lib existed, a "No such file
or directory" message was emitted. This message was harmless, but is now
suppressed in this situation.

Typecast bli_getopt() return value in testsuite.
Details:
- In the test suite driver, inserted an explicit typecast of the return
value of bli_getopt() prior parsing. The lack of typecast caused a
problem on at least one system whereby a return value of -1 was
interpreted as garbage character. Thanks to Francisco Igual for finding
and submitting this fix.

Allow building outside source distribution.
Details:
- Modified build system (mostly configure and top-level Makefile) so that
a user can build a BLIS library outside of the top-level directory of
the source distribution.
- Added "test" target to Makefile so that the user can run "make test",
which will compile, link, and run the testsuite binary. This works even
if the build directory is externally located, thanks to the test suite
binary's new -g and -o command-line options. Also, when creating the
test suite via the top-level Makefile, the linking is against the
local archive, in lib/<configname>, rather than at <install_prefix>/lib.
- Modified testsuite/Makefile so that it links against the library built
locally, in ../lib/<configname>.
- Added "-lm" to LDFLAGS of most configurations' make_defs.mk.
- Various other cleanups to build system.

Implemented bli_getopt().
Details:
- Added bli_getopt.c and .h files to frame/base. These files implement
a custom version of getopt(), which may be used to parse command line
options passed into a program via argc/argv. I am implementing this
function myself, as opposed to using the version available via unistd.h,
for portability reasons, as the only requirements are string.h (which
is available via the standard C library).
- Modified test suite to allow the user to specify the file name (and/or
path) to the parameters and operations input files: -g may be used to
specify the general input file and -o to specify the operations input
file). If -g or -o or both are not given, default filenames are assumed
(as well as their existence in the current directory).

Meant to include this change in a0331fb1.
- Changed template configuration to use 64-bit integers (for both BLIS
and the BLAS compatibility layer).

Removed error checks in netlib->BLIS param mapping
Details:
- Disabled error checking in netlib-to-BLIS parameter mapping functions.
If the char value input to these functions was not one of the defined
values, bli_check_error_code() with the appropriate error code value
would be called, resulting in an abort(). This was unnecessary and
redundant since these routines are currently only used within the
BLAS compatibility layer, and they are only called AFTER parameter
checking has already been performed on the original BLAS char values.
If the application tried to override xerbla() to prevent an abort()
from being called, this error checking would still get in the way.
Thus, instead of reporting the error situation to the framework (ie:
calling abort()), an arbitrary BLIS parameter value is now chosen and
the function returns normally. Thanks to Jeff Hammond for finding and
reporting this issue.

Store variable panel strides in trmm/trsm auxinfo.
Details:
- Changed the value being stored into the auxinfo_t structure in trmm
and trsm macro-kernels. Whereas before we stored whatever value was
provided to the macro-kernel implementation via ps_a/ps_b, now we
store the stride that will advance to the next variable-length
micro-panel of the triangular matrix A (left) or B (right).
- Whitespace changes to the files affected above.

Macroized conditionals for a2/b2 in macro-kernels.
Details:
- Replaced conditional expressions in macro-kernels related to computing
the addresses a2 and b2 (a_next and b_next) with a preprocessor macro

- Updated gemm_ukr module to use auxinfo_t argument.

Introduced auxinfo_t argument to micro-kernels.
Details:
- Removed a_next and b_next arguments to micro-kernels and replaced them
with a pointer to a new datatype, auxinfo_t, which is simply a struct
that holds a_next and b_next. The struct may hold other auxiliary
information that may be useful to a micro-kernel, such as micro-panel
stride. Micro-kernels may access struct fields via accessor macros
defined in bli_auxinfo_macro_defs.h.
- Updated all instances of micro-kernel definitions, micro-kernel calls,
as well as macro-kernels (for declaring and initializing the structs)
according to above change.

Added "ri" scalar macros.
Details:

imaginary components separately, named like the previous set except
with the "ris" (instead of "s") suffix.
- Redefined the previous set of scalar macros (those that take arguments
"whole") in terms of the new "ri" set.
- Renamed setris and getris macros to sets and gets.
- Renamed setimag0 macros to seti0s.
- Use bli_?1 macro instead of a local constant in bla_trmv.c, bla_trsv.c.

Date: Tue Dec 3 16:08:30 2013 -0600
Added new "attached" scalar representation.
Details:
- Added infrastructure to support a new scalar representation, whereby
every object contains an internal scalar that defaults to 1.0. This
facilitates passing scalars around without having to house them in
separate objects. These "attached" scalars are stored in the internal
atom_t field of the obj_t struct, and are always stored to be the same
datatype as the object to which they are attached. Level-3 variants no
longer take scalar arguments, however, level-3 internal back-ends stll
do; this is so that the calling function can perform subproblems such
as C := C - alpha * A * B on-the-fly without needing to change either
of the scalars attached to A or B.
- Removed scalar argument from packm_int().
- Observe and apply attached scalars in scalm_int(), and removed scalar
from interface of scalm_unb_var1().
- Renamed the following functions (and corresponding invocations):
bli_obj_init_scalar_copy_of()
-> bli_obj_scalar_init_detached_copy_of()
bli_obj_init_scalar() -> bli_obj_scalar_init_detached()
bli_obj_create_scalar_with_attached_buffer()
-> bli_obj_create_1x1_with_attached_buffer()
bli_obj_scalar_equals() -> bli_obj_equals()
- Defined new functions:
bli_obj_scalar_detach()
bli_obj_scalar_attach()
bli_obj_scalar_apply_scalar()
bli_obj_scalar_reset()
bli_obj_scalar_has_nonzero_imag()
bli_obj_scalar_equals()
- Placed all bli_obj_scalar_* functions in a new file, bli_obj_scalar.c.
- Renamed the following macros:
bli_obj_scalar_buffer() -> bli_obj_buffer_for_1x1()
bli_obj_is_scalar() -> bli_obj_is_1x1()
- Defined new macros to set and copy internal scalars between objects:
bli_obj_set_internal_scalar()
bli_obj_copy_internal_scalar()
- In level-3 internal back-ends, added conditional blocks where alpha and
beta are checked for non-unit-ness. Those values for alpha and beta are
applied to the scalars attached to aliases of A/B/C, as appropriate,
before being passed into the variant specified by the control tree.
- In level-3 blocked variants, pass BLIS_ONE into subproblems instead of
alpha and/or beta.
- In level-3 macro-kernels, changed how scalars are obtained. Now, scalars
attached to A and B are multiplied together to obtain alpha, while beta
is obtained directly from C.
- In level-3 front-ends, removed old function calls meant to provide
future support for mixed domain/precision. These can be added back later
once that functionality is given proper treatment. Also, removed the
creating of copy-casts of alpha and beta since typecasting of scalars
is now implicitly handled in the internal back-ends when alpha and
beta are applied to the attached scalars.

Unimplemented kernels now call reference.
Details:
- Updated arm, bgq, loongson3a, and x86_64 kernels so that unimplemented
datatypes call the corresponding reference kernel. Previously, these
kernel functions called abort() with a "not yet implemented" error
message.

Unimplemented kernels now call reference.
Details:
- Updated micro-kernels for arm, bgq, loongson3a, and x86_64 so that
unimplemented kernel functions simply call the corresponding reference
implementation. (Previously, these unimplemented functions would
abort() with a "not yet implemented" message.)

Removed optional scaling from packm control tree.
Details:
- Removed does_scale field from packm control tree node and
bli_packm_cntl_obj_create() interface. Adjusted all invocations of
_cntl_obj_create() accordingly.
- Redefined/renamted macros that are used in aliasing so that now,
bli_obj_alias_to() does a full alias (shallow copy) while
bli_obj_alias_for_packing() does a partial alias that preserves the
pack_mem-related fields of the aliasing (destination) object.
- Removed bli_trmm3_cntl.c, .h after realizing that the trmm control tree
will work just fine for bli_trmm3().
- Removed some commented vestiges of the typecasting functionality needed
to support heterogeneous datatypes.

Attempting to fix errors in bgq build.
Details:
- Removed restrict declaration from b_cast and c_cast from
bli_trsm_lu_ker_var2.c and bli_trsm_rl_ker_var2.c. Curiously, they
are causing problems for xlc only in those two files and no other
macro-kernels.
- Fixed (hopefully) kernel function parameter type declarations in
kernels/bgq/1f/bli_axpyf_opt_var1.c and kernels/bgq/3/bli_gemm_8x8.c.

Outer-to-inner 'restrict' fix in macro-kernels.
Details:
- Fixed sloppy placement of 'restrict' pointer declarations in level-3
macro-kernels. Previously, all restricted pointers were being declared
at the outer-most function scope level. While this violates the C99
standard, very few of the compilers used with BLIS so far have seemed
to care. The lone exception has been IBM's xlc. Thanks to Tyler Smith
for identifying this bug (and suggesting the fix).

Added object wrappers to 1f test suite modules.
Details:
- Added missing object wrappers to level-1f test suite modules. This was
only apparent if you were configuring with something other than the
reference configuration.
- Commented out object-wrappers in level-1f front-ends. These were not
working as intended the reference configuration was selected, because
most kernel sets, such as those in the template set, do not have object
wrappers.
- Whitespace changes to template micro-kernels.
- Comment changes to template level-1f kernel headers.

Changed dim_t and inc_t to be signed integers.
Details:
- Redefined dim_t and inc_t in terms of gint_t (instead of guint_t).
This will facilitate interoperability with Fortran in the future.
(Fortran does not support unsigned integers.)
- Redefined many instances of stride-related macros so that they return
or use the absolute value of the strides, rather than the raw strides
which may now be signed. Added new macros bli_is_row_stored_f() and
bli_is_col_stored_f(), which assume positive (forward-oriented) strides,
and changed the packm_blk_var[23] variants to use these macros instead
of the existing bli_is_row_stored(), bli_is_col_stored().
- Added/adjusted typecasting to to various functions/macros, including
bli_obj_alloc_buffer(), bli_obj_buffer_at_off(), and various pointer-
related macros in bli_param_macro_defs.h.
- Redefined bli_convert_blas_incv() macro so that the BLAS compatibility
layer properly handles situations where vector increments are negative.
Thanks to Vladimir Sukharev for pointing out this issue.
- Changed type of increment parameters in bli_adjust_strides() from dim_t
to inc_t. Likewise in bli_check_matrix_strides().
- Defined bli_check_matrix_object(), which checks for negative strides.
- Redefined bli_check_scalar_object() and bli_check_vector_object() so
that they also check for negative stride.
- Added instances of bli_check_matrix_object() to various operations'
_check routines.

Fixed a bug related to Hermitian matrix diagonals.
Details:

diagonal elements of Hermitian matrices were already zero. This property
is now enforced when the matrix is packed (bli_packm_blk_var2). Thanks
to Vladimir Sukharev for reporting this bug.
- Minor comment updates to template kernels.

Added scaling to abval2s, sqrt2s macros.
Details:

and overflow from squaring the real and imaginary components. (This is
the same technique used to fix recent bugs in invscals/invscaljs and
inverts.)

Fixed bug in complex invscals.
Details:
- Fixed complex inversion in invscals and invscaljs whereby the
imaginary component was being computed incorrectly.
- Use bli_fmaxabs() instead of bli_fabs() when choosing the scalar
in inverts, invscals, and invscaljs.
- Changed bli_abs() and bli_fabs() macro definitions to use "<="
operator instead of "<".

Fixed bugs in scalm and setm.
Details:
- Fixed bugs in scalm and setm that resulted in segmentation faults when
beta is not the same type as the matrix operand. Thanks to Vladimir
Sukharev for reporting this bug.
- Changed axpym and scal2m front-ends in fashion similar to that of scalm
and setm; namely, the alpha scalar is copy-cast the type of the first
matrix operand.
- Changed the template and reference configurations' bli_config.h files
so that the number of memory allocator blocks of A and B are set based
on BLIS_MAX_NUM_THREADS.
- Comment updates to bli_obj.c and variable rename in bla_nrm2.c.

unnecessarily over/under-flowing. Thanks for Vladimir Sukharev for
reporting this bug.
- Comment update to bli_sumsqv_unb_var1.c.

Added fusing factors, MR/NR to test suite output.
Details:
- Updated the test suite driver (and modules where appropriate) so that
the level-1f fusing factors are output along with the variable dimension.
While this is not strictly necessary, since the fusing factors are output
in the initial parameter summary, it allows extra reassurance to the user
since the fusing factors appear alongside the variable dimension, which
together give a complete picture of the problem size. Similar changes were
made for outputting the register blocksizes when reporting results for the
micro-kernel test modules.

Added test suite modules for level-1f, 3 kernels.
Details:
- Added test modules in test suite for level-1f kernels and level-3
micro-kernels. (Duplication in the micro-kernels, for now, is NOT
supported by these test modules.)
- Added section override switches to test suite's input.operations file.
- Added obj_t APIs for level-1f front-ends and their unblocked variants to
facilitate the level-1f test modules. Also added front-end for dupl
operation.
- Added obj_t-based check routines for level-1f operations, which are
called from the new front-ends mentioned above.
- Added query routines for axpyf, dotxf, and dotxaxpyf that return fusing
factors as a function of datatype, which is needed by their respective
test modules.
- Whitespace changes to bli_kernel.h of all existing configurations.

Added section overrides to test suite.
Details:
- Added new lines of input to the test suite's input.operations file, which
allows the user to disable entire sections (levels) of tests. Before this
change, the user had to manually disable each operation tests's "master
switch". (This is why input.operations.0 existed: to allow a more
convenient starting point for someone who only wanted to test one or a
few operations.)

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Sep 30 12:58:18 2013 -0500
Added template implementations and other tweaks.
Details:
- Added a 'template' configuration, which contains stub implementations of the
level 1, 1f, and 3 kernels with one datatype implemented in C for each, with
lots of in-file comments and documentation.
- Modified some variable/parameter names for some 1/1f operations. (e.g.
renaming vector length parameter from m to n.)
- Moved level-1f fusing factors from axpyf, dotxf, and dotxaxpyf header files
to bli_kernel.h.
- Modifed test suite to print out fusing factors for axpyf, dotxf, and
dotxaxpyf, as well as the default fusing factor (which are all equal
in the reference and template implementations).
- Cleaned up some sloppiness in the level-1f unb_var1.c files whereby these
reference variants were implemented in terms of front-end routines rather
that directly in terms of the kernels. (For example, axpy2v was implemented
as two calls to axpyv rather than two calls to AXPYV_KERNEL.)
- Changed the interface to dotxf so that it matches that of axpyf, in that
A is assumed to be m x b_n in both cases, and for dotxf A is actually used
as A^T.
- Minor variable naming and comment changes to reference micro-kernels in
frame/3/gemm/ukernels and frame/3/trsm/ukernels.

Removed default configuration behavior.
Details:
- Changed the configure script so that it no longer defaults to the
reference configuration. This change is being made so that the
developer has a firm awareness of which configuration is being used
to configure BLIS. Thanks to Mike Kistler and Bryan Marker for this
suggested change.

Minor improvements to static memory allocator.
Details:
- Expanded on cpp macro definitions from bli_mem.c and relocated them to
a new header file, frame/include/bli_mem_pool_macro_defs.h. The expanded
functionality includes computing the pool size for each datatype (using
that datatype's cache blocksizes) and using the maximum to size the
actual pool array. This addresses the somewhat common pitfall whereby a
developer updates cache blocksizes in bli_kernel.h for only one datatype
(say, single-precision real), while the memory pools are sized using the
double-precision real values. Then, when the developer attempts to link
to and run a level-3 BLIS routine (e.g. dgemm), the library aborts with
a message saying the static memory pool was exhausted. Clearly, this
message is misleading when the pool was not sized properly to begin with.
- Removed previously disabled code in bli_kernel_macro_defs.h that was
meant to check for size consistency among the various cache blocksizes.
(Obviously the memory pool size-based solution mentioned above is better.)
- Added BLIS_SIZEOF_? cpp macros to bli_type_defs.h. This seemed like a
reasonable place to put these constants, rather than further crowd up
bli_config.h.
- Updated testsuite driver to output memory pool sizes for A, B, and C.
- Minor comment updates to bli_config.h.
- Removed 'flame' configuration. It was beginning to get out-of-date, and
I hadn't used it in months. We can always re-create it later.

Added ESSL and Accelerate targets to test drivers.
Details:
- Added ESSL and Accelerate (OS X) targets to standalone test drivers'
Makefile in "test" directory. Thanks to Jeff Hammond for suggesting
/ providing this patch.

Various changes to treatment of integers.
Details:
- Added a new cpp macro in bli_config.h, BLIS_INT_TYPE_SIZE, which can be
assigned values of 32, 64, or some other value. The former two result in
defining gint_t/guint_t in terms of 32- or 64-bit integers, while the latter
causes integers to be defined in terms of a default type (e.g. long int).
- Updated bli_config.h in reference and clarksville configurations according
to above changes.
- Updated test drivers in test and testsuite to avoid type warnings associated
with format specifiers not matching the types of their arguments to printf()
and scanf().
- Inserted missing #include "bli_system.h" into blis.h (which was slated for
inclusion in d141f9eeb6d1).
- Added explicit typecasting of dim_t and inc_t to macros in
bli_blas_macro_defs.h (which are used in BLAS compatibility layer).
- Slight changes to CREDITS and INSTALL files.
- Slight tweaks to Windows build system, mostly in the form of switching to
Windows-style CRLF newlines for certain files.

Fixed set-but-not-used compiler (gcc) warnings.
Details:
- Used void-casts of certain variables to appease gcc (and perhaps other
compilers) when such variables are only used in the complex instances of
the functions. Special thanks to Karl Rupp for suggesting a portable fix
for these warnings.

Small fix to Windows defs.mk makefile fragment.
Details:
- Commented out a !include statement that was attempting to include a
version file that does not yet exist. For now, the version string is
hard-coded into defs.mk.

Added Windows build system.
Details:
- Added a 'windows' directory, which contains a Windows build system
similar to that of libflame's. Thanks to Martin for getting this up
and running.
- Spun off system header #includes into bli_system.h, which is included
in blis.h
- Added a Windows section to bli_clock.c (similar to libflame's).

Switched integer typedefs (again) to C types.
Details:
- Redefined gint_t and guint_t in terms of the standard C types long int
and unsigned long int, respectively.
- Changed testsuite default max problem size to 500.
- Changed testsuite input.operations to use square problems for level-3
operation tests.

Falling back to 32-bit integers for dim_t, etc.
Details:
- In light of recent segfaulting issues when compiling on 32-bit systems,
I've changed the default typedef for gint_t and guint_t from int64_t and
uint64_t to int32_t and uint32_t, respectively.
- Disabled 64-bit integers in the blas2blis layer for the reference
configuration.
- Added type sizes of gint_t, guint_t, and the four floating-point datatypes
to introductory output of the testsuite.

Applied temp fix to typecasting bug in testsuite.
Details:
- Applied a temporary fix to the typecasting bug in the testsuite driver.
The fix involves casting both numerator and denominator to unsigned long.
This fix is more voodoo than science, as I can't be sure why it even
works.

- Encounted a bizarre typecasting bug whereby the test suite was not
computing the proper dimension from the problem size and dimension
specification when the latter was set to -3. Will investigate.
Thanks to Fran for finding this "bug".

Generalized matlab and file output in testsuite.
Details:
- Added a new option in input.general that allows outputting in
matlab/octave format so that one can output in matlab format
independently from outputting to files.
- Adjusted input.operations according to above.
- Added input.operations.0 and input.operations.1 with all options
disabled and enabled, respectively.

Fixed bug in bli_acquire_mpart_t2b(), _l2r().
Details:
- Fixed a bug in bli_acquire_mpart_t2b() and bli_acquire_mpart_l2r()
that cause incorrect partitioning when SUBPART0 was requested. This
bug was introduced in 46d3d09d49ad. Thanks to Bryan for isolating
this bug.
- Removed dupl kernels from kernels/x86_64/3 directory.
- Uncommented beta == 0 optimizaition code in
kernels/x86_64/3/bli_gemm_opt_d4x4.c.

Moved init_safe(), finalize_safe() to BLAS compat.
Details:
- Moved the bli_init_safe() and bli_finalize_safe() function calls from the
BLAS-like BLIS layer to the BLAS compatibility layer. Having these auto-
initializers in the BLIS layer wasn't buying us anything because the user
could still call the library with uninitialized global scalar constants,
for example. Thus, we will just have to live with the constraint that
bli_init() MUST be called before calling ANY routine with a bli_ prefix.
- Added the missing _init_safe() and finalize_safe() calls to the level-1
BLAS compatibility wrappers.

Miscellaneous updates.
Details:
- Changed the BLIS_HEAP_STRIDE_ALIGN_SIZE in the configurations from 16 to
BLIS_CACHE_LINE_SIZE (typically 64).
- Changed the use of nr in sizing of bd buffer to packnr in level-3 macro-
kernels.
- Reformulated gemm_ker_var2 to look more like the other level-3 macro-
kernels, in that the interior and edge-case handling is expressed once
inside the loops in the n and m dimensions, rather than the edge-case
handling being "unrolled" and expressed as distinct code regions. The
previous macro-kernel now lives in retired form in the subdirectory
other/bli_gemm_ker_var2.c.old.
- Updated experimental gemm_ker_var5 according to above change.
- Fixed bug in bli_her2k.c whereby incorrect transformations were being
applied to optimize the macro-kernel accesses pattern on C when C is
row-stored.
- Various updates inside of test/exec_sizes.

Fixed cpp guard typos in frame/compat/check files.
Details:
- Fixed instances of BLIS_ENABLE_BLIS2BLAS that should have been
BLIS_ENABLE_BLAS2BLIS. Thanks to Tyler for catching this.
- Fixed various syntax errors in the code that had yet to be compiled
due to the aforementioned bug.

Added basic OpenMP-based gemm and packm files.
Details:
- Integrated Tyler's parallelized packm_blk_var2 and gemm_ker_var2
into the following auxiliary files
frame/1m/packm/other/bli_packm_blk_var2.c
frame/3/gemm/other/bli_gemm_ker_var2.c
The routine in the first file uses a basic OpenMP parallel region to
parallelize the packing of blocks of A and panels of B, while the
second uses a similar parallel region to parallelize along the n
dimension of the gemm macro-kernel.

Tightened some macros that detect datatypes.
Details:

the "special" bit is taken into account so that BLIS_INT is differentiated
from BLIS_FLOAT.
- Whitespace changes to bli_obj_macro_defs.h.
- Removed BLIS_SPECIAL_BIT definition from bli_type_defs.h, since it wasn't
being used.

Added BLAS error checking to compatibility layer.
Details:
- Added frame/compat/check directory, which now houses companion _check()
routines for each of the BLAS wrappers in frame/compat. These _check()
routines are called from the compatibility wrappers and mimic the
error-checking present in the netlib BLAS.
- Edited bla_xerbla.c so that xerbla() translates the operation string to
uppercase before printing.
- Redefined util routines in frame/compat/f2c/util in terms of level0
macros.
- Added prototypes for util routines, f2c routines, lsame(), and xerbla().
- Commented out prototypes in test/test_*.c since Fortran integers are now
int64_t by default (and the prototypes that were present in the files
used int).
- Removed redundant #include "bli_f2c.h" in bli_?lamch.c and bli_lsame.c,
since blis.h was already being included.
- Other minor changes to code in frame/compat/f2c.

Added support for C99 complex types/arithmetic.
Details:
- Added support for C99 complex types to bli_type_defs.h and overloaded
complex arithmetic to the scalar-level macros in include/level0. This
includes a somewhat substantial reorganization and re-layering of much
of the existing machinery present in the level0 macros.
- Added new #define for BLIS_ENABLE_C99_COMPLEX to bli_config.h files,
commented-out by default, which optionally enables the use of built-in
C99 complex types and arithmetic.
- Minor changes to clarksville and reference configs' make_defs.mk files.
- Removed macro definitions from bli_param_macro_defs.h which was not being
used (bli_proj_dt_to_real_if_imag_eq0).

Fixed bugs in trsm, trmm macro-kernels.
Details:
- Fixed a bug in trsm_rl_ker_var2() caused by incorrect edge case handling.
- Fixed a bug in trsm_rl_ker_var2() and trsm_ru_ker_var2() whereby k was
incorrectly being adjusted upward by MR, instead of NR. The rl and ru
trmm macro-kernels were updated in a similar fashion.
- Fixed a bug in trsm_ru_ker_var2() that was due to a missing negation on
diagoffb when recomputing k to skip a zero region below where the
diagonal intersects the right side of the block. The corresponding
trmm macro-kernel was also updated.
- Fixed a bug in trsm_ru_ker_var2() where the the adjustment of k (by NR)
needed to be placed AFTER the block that recomputes k to skip the zero
region (if present). The other three trsm macro-kernels, as well as the
trmm macro-kernels, were updated in the same manner, for consistency.
- Fixed a bug in trmm_lu_ker_var2() in which the wrong dimension (n) was
being updated to skip a zero region to the left of where the diagonal
of A intersects the top edge of the block.
- Comment updates to all trsm and trmm macro-kernels.
- Comment updates to bli_packm_init.c.

Removed copynzv, copynzm and related codes.
Details:
- Removed copynzv and copynzm operation directories. These operations
implemented a variation of copyv/m that, in the case of real source
and complex destination operands, leaves the imaginary component
untouched (rather than setting it to zero). I realize now that the
special case(s) (e.g. gemm with real A and B but complex C) that I
thought required this operation actually can be handled more simply.
- Removed level0 scalar macros implementing copynzs, copynzjs.

Added handling of restrict, stdint.h for non-C99.
Details:
- Removed the #include <stdint.h> from blis.h and inserted a cpp macro block
in bli_type_defs.h that #includes <stdint.h> for C++ and C99, and otherwise
manually typedefs the types we need (which, for now, are unconditionally
int64_t and uint64_t).
- Moved basic typedefs to top of bli_type_defs.h, and comment changes.
- Added cpp macro block to bli_macro_defs.h that #defines restrict as
nothing for C++ and non-C99.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Jul 8 15:20:34 2013 -0500
Migrated integer usage to stdint.h types.
Details:
- Changed the way bli_type_defs.h defines integer types so that dim_t,
inc_t, doff_t, etc. are all defined in terms of gint_t (general signed
integer) or guint_t (general unsigned integer).
- Renamed Fortran types fchar and fint to f77_char and f77_int.
- Define f77_int as int64_t if a new configuration variable,
BLIS_ENABLE_BLIS2BLAS_INT64, is defined, and int32_t otherwise.
These types are defined in stdint.h, which is now included in blis.h.
- Renamed "complex" type in f2c files to "singlecomplex" and typedef'ed
in terms of scomplex.
- Renamed "char" type in f2c files to "character" and typedef'ed in terms
of char.
- Updated bla_amax() wrappers so that the return type is defined directly
as f77_int, rather than letting the prototype-generating macro decide
the type. This was the only use of GENTFUNC2I/GENTPROT2I-related macros,
so I removed them. Also, changed the body of the wrapper so that a
gint_t is passed into abmaxv, which is THEN typecast to an f77_int
before returning the value.
- Updated f2c code that accessed .r and .i fields of complex and
doublecomplex types so that they use .real and .imag instead (now that
we are using scomplex and dcomplex).

Added experimental bli_gemm_ker_var5().
Details:
- Added support for an experimental gemm macro-kernel incrementally
packs one micro-panel of B at a time. This is useful for certain
special cases of gemm where m is small.
- Minor changes to default values of clarksville configuration.
- Defined BLIS_PACKED_BLOCKS as part of pack_t type, even though we
do not yet have any use (or implementation support) for block storage.
- Comment update to bli_packm_init.c.

Defined "total" blocksize query functions.
Details:
- Defined bli_blksz_total_for_type() and bli_blksz_total_for_obj() to query
the default blocksize plus blocksize extension (using the type or the type
of an object).
- Comment update in bli_packm_cxk.c.

Consolidated lower/upper her[2]k blocked variants.
Details:
- Consolidated lower and upper blocked variants for herk and her2k, and
renamed the resulting variants, according to the same changes recently
made to trmm and trsm.
- Implemented support for four new subpartitions types:
BLIS_SUBPART1T
BLIS_SUBPART1B
BLIS_SUBPART1L
BLIS_SUBPART1R
which correspond to "merged" partitions that include the middle "1"
partition as well as either the neighboring "0" or "2" partition. This is
used to clean up code in herk/her2k var2 that attempts to partition away
the strictly zero region above or below the diagonal of a matrix operand
that is being marched through diagonally.
- Added safeguards to herk macro-kernels that skip any leading or trailing
zero region in the panel of C that is passed in. This is now needed given
that herk/her2k var1 no longer partitions off this zero region before
calling the macro-kernel (via bli_her[2]k_int()).
- Updated comments and other whitespace changes to trmm/trsm macro-kernels.

Added row-storage optimizations for trmm, trsm.
Details:
- Implemented algorithmic optimizations for trmm and trsm whereby the right
side case is now handled explicitly, rather than induced indirectly by
transposing and swapping strides on operands. This allows us to walk through
the output matrix with favorable access patterns no matter how it is stored,
for all parameter combinations.
- Renamed trmm and trsm blocked variants so that there is no longer a
lower/upper distinction. Instead, we simply label the variants by which
dimension is partitioned and whether the variant marches forwards or
backwards through the corresponding partitioned operands.
- Added support for row-stored packing of lower and upper triangular matrices
(as provided by bli_packm_blk_var3.c).
- Fixed a performance bug in bli_determine_blocksize_b() whereby the cache
blocksize extensions (if non-zero) were not being used to appropriately size
the first iteration (ie: the bottom/right edge case).
- Updated comments in bli_kernel.h to indicate that both MC and NC must be
whole multiples of MR AND NR. This is needed for the case of trsm_r where,
in order to reuse existing left-side gemmtrsm fused micro-kernels, the
packing of A (left-hand operand) and B (right-hand operand) is done with
NR and MR, respectively (instead of MR and NR).

Use separate CFLAGS for "kernels" directories.
Details:
- Added a new "special" directory type: any source code within directories
named "kernels" will be compiled with a separate CFLAGS_KERNELS set of
compiler flags. This allows the developer to specify a separate set of
flags (e.g. optimization flags) for compiling kernels while maintaining a
standard set for regular framework code.
- Fixed a bug in the top-level Makefile that was causing "noopt" code
to be compiled with the standard set of compilation flags.
- Updated make_defs.mk in reference, flame, and clarksville configurations
according to above changes.

Date: Tue Jun 11 12:18:39 2013 -0500
Various level-3 optimizations for row storage.
Details:
- Implemented remaining two cases within bli_packm_blk_var2(), which allow
packing from a lower or upper-stored symmetric/Hermitian matrix to column
panels (which are row-stored). Previously one could only pack to row panels
(which are column-stored).
- Implemented various optimizations in the level-3 front-ends that allow more
favorable access through row-stored matrices for gemm, hemm, herk, her2k,
symm, syrk, and syr2k.
- Cleaned up code in level-3 front-ends that has to do with setting target and
execution datatypes.

Added beta == 0 optimization to x86_64 ukernel.
Details:
- Modified x86_64 gemm microkernel so that when beta is zero, C is not read
from memory (nor scaled by beta).
- Fixed minor bug in test suite driver when "Test all combinations of storage
schemes?" switch is disabled, which would result in redundant tests being
executed for matrix-only (e.g. level-1m, level-3) operations if multiple
vector storage schemes were specified.
- Restored debug flags as default in clarksville configuration.

implementation of axpyf kernel.
- Fixed over- and under-cautious handling of unaligned operands in vector
intrinsic implementation of dotxaxpyf kernel.

Updated level-1/-1f [vector intrinsic] kernels.
Details:
- Updated level-1/-1f kernels so that non-unit and un-aligned cases are
handled by reference implementation (rather than aborted).
- Added -fomit-frame-pointer to default make_defs.mk for clarksville
configuration.
- Defined bli_offset_from_alignment() macro.
- Minor edits to old test drivers.

Replaced axpys usage with subs in trsv.
Details:
- Replaced instances of axpys with alpha equal to -1 with subs.
- Use BLIS_MAX_TYPE_SIZE to define BLIS_CONSTANT_SLOT_SIZE instead of
sizeof(dcomplex).
commit 2d9c667f3c48a12cab64e5ad09d5fcb9f4c19d78
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri May 24 16:28:10 2013 -0500
Fixed x86_64 kernel bugs and other minor issues.
Details:
- Fixed bugs in trmv_l and trsv_u due to backwards iteration resulting in
unaligned subpartitions. We were already going out of our way a bit to
handle edge cases in the first iteration for blocked variants, and this
was simply the unblocked-fused extension of that idea.
- Fixed control tree handling in her/her2/syr/syr2 that was not taking
into account how the choice of variant needed to be altered for
upper-stored matrices (given that only lower-stored algorithms are
explicitly implemented).
- Added bli_determine_blocksize_dim_f(), bli_determine_blocksize_dim_b()
macros to provide inlined versions of bli_determine_blocksize_[fb]() for
use by unblocked-fused variants.
- Integrated new blocksize_dim macros into gemv/hemv unf variants for
consistency with that of the bugfix for trmv/trsv (both of which now
use the same macros).
- Modified bli_obj_vector_inc() so that 1 is returned if the object is a
vector of length 1 (ie: 1 x 1). This fixes a bug whereby under certain
conditions (e.g. dotv_opt_var1), an invalid increment was returned, which
was invalid only because the code was expecting 1 (for purposes of
performing contiguous vector loads) but got a value greater than 1 because
the column stride of the object (e.g. rho) was inflated for alignment
purposes (albeit unnecessarily since there is only one element in the
object).
- Replaced some old invocations of set0 with set0s.
- Added alpha parameter to gemmtrsm ukernels for x86_64 and use accordingly.
- Fixed increment bug in cleanup loop of gemm ukernel for x86_64.
- Added safeguard to test modules so that testing a problem with a zero
dimension does not result in a failure.
- Tweaked handling of zero dimensions in level-2 and level-3 operations'
internal back-ends to correctly handle cases where output operand still
needs to be scaled (e.g. by beta, in the case of gemm with k = 0).

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri May 3 17:24:58 2013 -0500
Renamed _set_trans(), _trans_status() macros.
Details:
- Renamed the following macros:
bli_obj_set_trans() -> bli_obj_set_onlytrans()
bli_obj_trans_status() -> bli_obj_onlytrans_status()
to remove ambiguity as to which bits are read/updated.

Date: Wed May 1 15:06:30 2013 -0500
Unconditionally check memory pool(s) for errors.
Details:
- Changed bli_mem_acquire_m() in bli_mem.c so that we still check if the
memory pool is exhausted before checking out and returning a block, even
if BLIS error checking has been disabled. These errors are useful because
they likely indicate that BLIS was improperly configured for the code
being run.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Apr 30 19:35:54 2013 -0500
Absorbed blocksize extensions into main objects.
Details:
- Revamped some parts of commit b6ef84fad1c9 by adding blocksize extension
fields to the blksz_t object rather than have them as separate structs.
- Updated all packm interfaces/invocations according to above change.
- Generalized bli_determine_blocksize_?() so that edge case optimization
happens if and only if cache blocksizes are created with non-zero
extensions.
- Updated comments in bli_kernel.h files to indicate that the edge case
blocksize extension mechanism is now available for use.

Added option to disable err checking in testsuite.
Details:
- Added a new line to input.general that allows one to specify the error-
checking level to use for each BLIS experiment. The only two levels
supported for now are "no error checking" and "full error checking".

Use cntl trees that block in n dimension.
Details:
- Updated _cntl.c files for each level-3 operation to induce blocked
algorithms that first paritition in the n dimension with a blocksize
of NC. Typically this is not an issue since only very large problems
exceed that of NC. But developers often run very large problems, and
so this extra blocking should be the default.
- Removed some recently introduced but now unused macros from
bli_param_macro_defs.h.

Use PASTEMAC in macro-kernels (over MAC2 or MAC3).
Details:
- Replaced multi-type invocations of copys_mxn, xpbys_mxn, etc. (PASTEMAC2
and PASTEMAC3) with those that only use a single type (PASTEMAC).
- Added extra macros to bli_adds_mxn_uplo.h and bli_xpbys_mxn_uplo.h to
accommodate above change.
- Fixed comment typo in bli_config.h files.
- Added .nfs* pattern to .gitignore.

Fixed computation of b_next in L3 macro-kernels.
Details:
- Restructured herk_l and herk_u macro-kernels in the imagine of trmm
and trsm, in that the edge cases are captured by the main loop, rather
than trying to have "cleanup" sections that result in four distinct
parts (interior, bottom edge, right edge, bottom-right edge) of the
code.
- Fixed the way b_next was being computed in the non-gemm level-3
macro-kernels (herk, trmm, trsm). The way they are computed now matches
that of gemm.

Fixed rare edge case bug in herk_l macro-kernel.
Details:
- Fixed a potential bug in herk_l at the m_left edge case. If MR was
chosen to be much larger than NR, then one could encounter edge cases
in the the MC dimension that fall entirely below the diagonal, which
the previous implementation of the herk_l macro-kernel was not allowing
for.

Updated x86 gemmtrsm ukernels to use alpha.
commit 9d10d7dd9bc92a993fea7162bfa5983f75506f49
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Apr 23 16:00:18 2013 -0500
Added a_next, b_next arguments to micro-kernels.
Details:
- Added two more arguments to the gemm and gemmtrsm microkernels: the
addresses of the next micro-panels of A and B. By passing these
pointers into the micro-kernel, we allow the micro-kernel author to
prefetch micro-panels of A and B as necessary (though this is
completely optional; these addresses may also be safely ignored).
- Updated all seven macro-kernels so that they compute and pass in
a_next and b_next. Note that ONLY the gemm macro-kernel computes
a_next and b_next with the precise semantics we want. I will go back
and fix the other macro-kernels in the near future.
- Added 'restrict' to various micro-kernels from which it was missing.

Added code for backward edge-case blocking.
Disabled:
- Edited bli_determine_blocksize_b() to include experimental (and
currently disabled) code that computes extended blocks.
- Updated commnts relate to above changes.
- Enabled use of x86 gemmtrsm ukernel in config/flame/bli_kernel.h.

Updated dupl implementation to use PACKNR and NR.
Details:
- Updated frame/util/dupl/bli_dupl_unb_var1.c to utilize PACKNR and NR
explicitly so navigate b1 so that situations where PACKNR > NR are
supported.
- Moved the 4x2 and 4x4 reference micro-kernels in frame/3/gemm/ukernels and
frame/3/trsm/ukernels to kernels/c99/.
- Updated clarksville and flame configurations.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Apr 21 15:10:34 2013 -0500
Disabled blocksize checks for memory pools.
Details:
- Temporarily disabled checks that ensure that enough memory will be allocated
by the contiguous memory allocator for all types, given that the values for
double precision real are the ones used to allocate the space. These checks
can easily go awry in certain situations, especially if you are developing for
only one datatype. So for now, they are probably more trouble than they are
worth.
commit b6ef84fad1c9884c84b7f1350a0bcdfe1737e8f2
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Apr 21 15:00:24 2013 -0500
Allow ldim of packed micro-panels != MR, NR.
Details:
- Made substantial changes throughout the framework to decouple the leading
dimension (row or column stride) used within each packed micro-panel from
the corresponding register blocksize. It appears advantageous on some
systems to use, for example, packed micro-panels of A where the column
stride is greater than MR (whereas previously it was always equal to MR).
- Changes include:
- Added BLIS_EXTEND_[MNK]R_? macros, which specify how much extra padding
to use when packing micro-panels of A and B.
- Adjusted all packing routines and macro-kernels to use PACKMR and PACKNR
where appropriate, instead of MR and NR.
- Added pd field (panel dimension) to obj_t.
- New interface to bli_packm_cntl_obj_create().
- Renamed bli_obj_packed_length()/_width() macros to
bli_obj_padded_length()/_width().
- Removed local #defines for cache/register blocksizes in level-3 *_cntl.c.
- Print out new cache and register blocksize extensions in test suite.
- Also added new BLIS_EXTEND_[MNK]C_? macros for future use in using a larger
blocksize for edge cases, which can improve performance at the margins.

Fixed bug in compatibility layer (her2k/syr2k).
Details:
- Fixed a bug in the BLAS compatibility layer, specifically in bla_her2k.c
and bla_syr2k.c, that caused incorrect computation to occur when the BLAS
interface caller requests the [conjugate-]transpose case. Thanks to Bryan
Marker for reporting the behavior that led to this bug.

Changed old level3 test drivers to call front-ends.
Details:
- Changed old level-3 test drivers, in 'test' directory, to always call the
front-end object API instead of the internal back-end with the locally
defined control tree.

Date: Thu Apr 18 18:33:03 2013 -0500
Allow packm_init() to reacquire a too-small mem_t.
Details:
- Changed bli_packm_init() to react differently to a situation where a pack
obj_t has an already-allocated mem_t entry that has a buffer that is smaller
than what will be needed to hold the block/panel that now needs to be
packed. Previously, this situation was treated with an abort() since I
assumed something was horribly wrong. I have changed the code so that it now
reacts by releasing the previous mem_t and re-acquires a new mem_t with the
new information. (This change was done at the request of Bryan Marker to
facilitate code generation via DxT.)

Fixed bug in packing block of A for hemm/symm.
Details:
- Fixed a bug in bli_packm_blk_var2() that affected the packing functionality
of hemm and symm. The bug occurs whenever attempting to pack a Hermitian or
symmetric matrix where the block of A being packed intersects the diagonal,
but some of its micro-panels do not intersect the diagonal and lie completely
in the unstored region. Thanks to Francisco Igual for reporting this bug.
- Comment updates to both _blk_var2.c and _blk_var3.c.

Activated bli_packm_acquire_mpart_t2b().
Details:
- Removed the overly-paranoid bli_abort() from the end of
bli_packm_acquire_mpart_t2b(), to allow others to experiment with
partitioning through packed blocks of A. Also, and more importantly,
changed an earlier check that was causing an erroneous (but
coincidentally redundant) abort(). Also, updated some of the comments
in bli_packm_part.c.

Allow creation of "empty" objects.
Details:

Fixed "root" object bug in bli_her[2]k/syr[2]k.
Details:
- Fixed an obscure bug in the front-ends for herk, her2k, syrk, and syr2k,
that manifested as the incorrect triangle being updated. It occurred when
the user would pass in a matrix object that was correctly marked as
symmetric/Hermitian and lower-stored, but whose root object was never marked
as lower (or upper). We now alias and re-assign root status for matrix C
within the front-ends. Note that trmm and trsm were already doing this,
albeit for a slightly different reason (to allow the internal back-end to
choose which algorithm to run--lower or upper--based on the uplo of the root
object for both left and right side cases). Thanks to Bryan Marker for
leading me to this bug.

Fixed overzealous type-checking in bli_getsc().
Details:
- Relaxed type checking in getsc so that the input object could be a constant
and not just a proper floating-point type. (If it is a constant, default to
extracting the dcomplex values.) Thanks to Bryan Marker for reporting this
bug.
- Added definition for bli_is_constant() in bli_param_macro_defs.h
- Comment updates to various level-0 scalar routines.

Date: Mon Apr 15 19:27:57 2013 -0500
Fixed bug in bli_obj_is_packed() and renamed.
Details:
- This macro is used to determine whether the partitioning routines should
call a corresponding packm_part routine instead. However, it was
unintentionally catching matrices that were marked as "packed" by virtue
of them simply being marked as BLIS_PACKED_UNSPEC in, say, bli_gemv().
The macro has now been renamed to bli_obj_is_panel_packed(), and now only
checks for row or column panel packing. (Note that I first attempted to
fix this bug in a571af816d72.) Thanks to Bryan Marker for reporting the
erroneous behavior that led me to this bug.

commit d9948c541c0446e20e249a1ccc83709ce51b7aa8
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Apr 15 10:21:26 2013 -0500
Tweak to test suite function string construction.
Details:
- Fixed a minor bug in the way that the test suite would construct function
name strings when the user anchored all parameters in input.operations.
In this case, the test driver would mistake this situation for one where
the operation simply had no parameters to begin with, and thus would not
include the parameter string in the function string that is output for
every result.

Fixed a bug in reference implementation of dupl.
Details:
- Fixed a bug in reference implementation of dupl (bli_dupl_unb_var1.c),
which resulted in incorrect duplication.
- Updated old test drivers according to recently updated packm control tree
creation interface.
- Added 'restrict' to x86 gemm microkernel interface.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sun Apr 14 19:05:33 2013 -0500
Modified bli_kernel.h include order in blis.h.
Details:
- Delayed #include of bli_kernel.h in blis.h to prevent a situation where
_kernel.h includes an optimized microkernel header, which uses BLIS types
such as dim_t and inc_t, which would precede the definition of those types
in bli_type_defs.h.
- Moved the #include of bli_kernel_macro_defs.h in bli_macro_defs.h to blis.h
(immediately after that of bli_kernel.h).

Removed gemmtrsm-, trsm-specific blocksize macros.
Details:
- Modified gemmtrsm micro-kernel wrappers to use new aliased blocksize macros
instead of operation-specific ones.
- Removed local, gemmtrsm-specific blocksize macro definitions found in
micro-kernel header files.
(Meant to include above changes in 31b100e7bf4a.)
- Added comments to reference gemmtrsm micro-kernel wrapper implementation.
commit 1a9f427b85bb95aaa9e54c8ff8ecad8734b361ee
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Apr 12 15:25:54 2013 -0500
Added/renamed alignment constants to _config.h.
Details:
- Added new memory alignment constants:
BLIS_HEAP_STRIDE_ALIGN_SIZE (previously assumed to be same as SYSTEM_MEM)
BLIS_CONTIG_ADDR_ALIGN_SIZE (previously assumed to be same as PAGE_SIZE)
BLIS_STACK_BUF_ALIGN_SIZE (previously not enforced)
and renamed existing ones
BLIS_SYSTEM_MEM_ALIGN_SIZE -> BLIS_HEAP_ADDR_ALIGN_SIZE
BLIS_CONTIG_MEM_ALIGN_SIZE -> BLIS_CONTIG_STRIDE_ALIGN_SIZE
to better convey what the alignment factor is used for (and what it is
not used for).
- Removed BLIS_ENABLE_SYSTEM_MEM_ALIGN. Dynamic memory alignment is now
disabled by setting BLIS_HEAP_STRIDE_ALIGN_SIZE to 1.
- Inserted instances of __attribute__((aligned(BLIS_STACK_BUF_ALIGN_SIZE)))
into macro-kernels to specify stack alignment of temporary buffers.
- Modified test suite driver to output new constants.
- Removed bli_align_dim_to_sys() and bli_align_dim_to_cmem(). Instead, we now
use bli_align_dim_to_size(), which takes a third argument (the desired
alignment).

Fixed an bug in axpyv/axpym when alpha is unit.
Details:
- Fixed bug whereby axpyv and axpym were incorrectly simplifying to a copy,
rather than an add, when alpha = 1. Thanks to Bryan Marker for identifying
this bug.

Moved _POSIX_C_SOURCE def to compiler cmd line.
Details:
- Removed the #define of _POSIX_C_SOURCE in bli_config.h (for both reference
and clarksville configurations) and added "-D_POSIX_C_SOURCE=200112L" to
the compiler command line arguments in make_defs.mk (for both configs).
Thanks to Devin Matthews for suggesting this change.

Appended 'f2c_' to abs, min, max macros in f2c.h.
Details:
- Renamed abs, min, max, dmin, and dmax macros in bli_f2c.h so that they
would not conflict with anything defined by the user (or the language).
Thanks to Devin Matthews for suggesting this fix.
- Updated all instances of the above macros accordingly.

Added new kernel blocksize macro aliases.
Details:
- Added new macros that alias level-3 cache and register blocksize macros
to names that can be constructed via the PASTEMAC macro. These aliased
macro definitions live inside bli_kernel_macro_defs.h, which is now
#included after bli_kernel.h.
- Modified macro-kernels to use new aliased blocksize macros instead of
operation-specific ones.
- Removed local, operation-specific kernel blocksize macro definitions
(found in macro-kernel header files).

Reverted testsuite object files' home to 'obj'.
Details:
- Removed 'obj' and 'lib' from .gitignore.
- Added testsuite/obj/.gitkeep (which is an empty file).

Fixed a performance bug in trsm.
Details:
- Fixed a bug in the reference implementations of the gemmtrsm wrappers
(bli_gemmtrsm_l_ref_mxn.c and bli_gemmtrsm_u_ref_mxn.c) whereby the
reference gemm microkernel was hard-coded, and thus always called, even
when GEMM_UKERNEL was defined to point to an optimzied microkernel. This
manifested as artificially low trsm performance for all problem sizes, but
especially for small problem sizes as it only affected blocks of A that
intersected the diagonal. Thanks to Mike Kistler of IBM for helping me
find this bug.
commit a7252e40b5c351eef9a1df531ea0ef25cb5fb705
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Apr 8 16:08:22 2013 -0500
Generate testsuite objects 'src'.
Details:
- Tweaked the testsuite makefile so that object files are stored in 'src'
rather than 'obj', since (a) the top-level .gitignore dictates that
obj directories are to be ignored, and (b) since git has problems
tracking empty directories. Now, users do not need to create their own
obj directories within their own local clones of BLIS.

Date: Mon Apr 8 15:00:13 2013 -0500
Fixed definition of bli_is_packed_object() macro.
Details:
- Changed the definition of bli_is_packed_object() so that it keys off of the
value of the pack schema bits in the info field of obj_t, rather than
comparing the obj_t buffer with that of the mem_t entry. This was the cause
of a very low probability bug whereby uninitialized memory caused the macro
to evaluate to TRUE even though the object in question was not packed.
Thanks to Vernon Austel of IBM for helping discover this bug.
- Changed an abort() in bli_packm_part() to a not-yet-implemented.

Fixed edge case handling bug in herk macrokernels.
Details:
- Fixed a bug present in bli_herk_l_ker_var2() and bli_herk_u_ker_var2() that
only manifests when BLIS is configured such that MR != NR. The bug involves
incorrectly detecting edge cases, which resulted in some parts of matrix C
potentially being skipped and not updated, depending on the problem size.
- Updated the default values of MR and NR in config/reference/bli_kernel.h to
8 and 4, respectively, so that I can better stress the framework on a
day-to-day basis. (The fact that they were both equal to 4 for so long is
why I did not stumble upon this bug much sooner.)
commit 7cbda15291d3e01300e71c286b9657b7ef0708bf
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Apr 4 15:25:43 2013 -0500
Added reference microkernels for arbitrary MR, NR.
Details:
- Added a new set of reference gemm, gemmtrsm, and trsm micro-kernels that
contain explicit loops over MR and NR, thus allowing them to be used
unmodified by developers who want to build a reference library with
custom register blocksizes.
- Changed config/reference/bli_kernel.h to use above ukernels by default.
- Changed interfaces of new and existing gemm, gemmtrsm, and trsm micro-kernels
to use 'restrict' keyword.
- Added -funroll-loops option to config/reference/make_defs.mk.
- Updated comments in bli_kernel.h describing constraints on register and
cache blocksizes.
- Updated _adds_mxn.h, _copys_mxn.h, and _xpbys_mxn.h macros files so that
single-char macros are also defined.

More memory alignment-related tweaks.
Details:
- Renamed BLIS_MEMORY_ALIGNMENT_SIZE to BLIS_CONTIG_MEM_ALIGN_SIZE.
- Renamed BLIS_ENABLE_MEMORY_ALIGNMENT to BLIS_ENABLE_SYSTEM_MEM_ALIGN.
- Added BLIS_SYSTEM_MEM_ALIGN_SIZE, which controls only the alignment
passed into posix_memalign() or equivalent.
- Defined new function, bli_align_dim_to_cmem(), which applies the
contiguous memory alignment (rather than the system/malloc alignment).

Memory alignment should always be enabled, and so this value should
always be defined.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Mar 26 12:43:14 2013 -0500
Align packed panel strides with system alignment.
Details:
- Pass panel strides through bli_align_dim_to_sys() to ensure that each
subsequent packed panel of A and B begins at an aligned address. (The
first panel is presumably aligned to system alignment because it is
aligned to a page boundary, which is typically much larger.)
- Rearranged code in packm_init_pack() to prevent additional conditional
blocks as a result of the aforementioned change.
- Adjusted contiguous memory allocator so that the system memory alignment
is used to allocate enough space for each block no matter what kind of
register blocking is used (even if register blocksize is unit and every
row/column needs maximal padding).
- Adjusted default blocksizes in reference configuration so that MC*KC
and KC*NC result in identical footprints for all datatypes.

Removed #include "blis2.h" from low-level headers.
Details:
- Removed #include of "blis2.h" from various lower-level, operation-specific
header files throughout the framework. Given that these low-level headers
are included within #blis2.h in a very specific order, #include'ing blis2.h
within them directly is unnecessary.

Added cpp guards to conflicting libflame typedefs.
Details:
- Added cpp guards around the definitions of dim_t, scomplex, and dcomplex.
This is a temporary hack to allow interoperability with libflame. (Similarly
temporary changes are being made to libflame's type definitions file.)

Renamed MAX_PREFETCH_BYTE_OFFSET to MAX_PRELOAD_.
Details:
- Renamed BLIS_MAX_PREFETCH_BYTE_OFFSET to
BLIS_MAX_PRELOAD_BYTE_OFFSET since "prefetch" is kind of a loaded word
(e.g. "prefetch" instructions, which are different than the particular
kind of prefetching/preloading referred to by this constant).

Relocated packed mem_t dimension fields to obj_t.
Details:
- Removed the m and n (and elem_size) fields from the mem_t object, and added
m_packed and n_packed fields to obj_t. These new fields track the same as
the old ones. From an abstraction standpoint, it seemed awkward to store
those dimensions inside the mem_t.
- Updated interfaces to bl2_mem_acquire_*() so that only a byte size argument
is passed in, instead of m, n, and elem_size.
- Updated bl2_packm_init_pack() and bl2_packv_init_pack() to inline the
functionality of bl2_mem_alloc_update_m() and bl2_mem_alloc_update_v(),
respectively.
- Updated packm variants to access the packed length and width fields from
their new locations.

commit e7d41229d3b1674e74f47d7f29fae004a745201a (tag: 0.0.4)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 15 17:12:36 2013 -0500
Re-implemented contiguous memory allocator.
Details:
- Completely re-wrote the contiguous memory allocator (bl2_mem.c). The new
allocator instantiates and initializes three separate memory pool objects,
each one associated with a separate array of contiguous memory blocks, each
block of fixed and uniform size. (The three pools are for allocating mc-by-kc
blocks of A, kc-by-nc panels of B, and mc-by-nc panels of C.) The pool
objects use a stack structure internally to track which blocks in the region
have been "checked out" to a thread and which are still available. Critical
regions are now clearly marked and adaptable to parallel environments (e.g.
OpenMP). Memory pools are set up when bl2_init() is called.
- Added a new field to the packm control tree node, which indicates what kind
of packed buffer is being allocated. The enumerated type for this argument
is defined as packbuf_t in bl2_type_defs.h.
- Updated level-3 _cntl.c files to pass in the appropriate value for a new
packbuf_t argument to bl2_packm_cntl_obj_create().
- Moved some macros called by packm_init_pack() from bl2_obj_macro_defs.h to
bl2_mem_macro_defs.h.
- Added BLIS_MAX_NUM_THREADS to bl2_config.h, which we use as the default
number of blocks of A reserved for the memory allocator.
- Deprecated bl2_align_dim(). Replaced usage with that of
bl2_align_dim_to_mult(). Turns out that typically we don't need to align
a dimension to the system alignment, since that value has to do with
starting addresses, whereas the values we are dealing with are unitless
dimensions.

Perform her2k var1 loops in sequence.
Details:
- Changed variant 1 of her2k so that the two rank-k products are computed
and accumulated in sequence rather than fused into one loop. This is
necessary if BLIS is to be configured to provide only enough contiguous
memory for one panel of B.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Mar 7 14:42:15 2013 -0600
Enhanced tracking of dimensions for mem_t objects.
Details:
- Added new fields to mem_t struct definition to track the allocated (as
opposed to the currently used) dimensions of the memory region. This
allows packm_init() to be more robust in situations where memory is
already allocated but is more than needed for the current packing job.
- Updated logic in bl2_obj_set_buffer_with_cached_packm_mem() macro, used
in packm_init(), to update the "currently used" dimensions of the mem_t
object if the requested dimensions are smaller than the allocated
dimensions.

- Changed bl2_obj_induce_trans() so that the transposition bit is no longer
updated as part of the macro. All current uses of the macro have been
coupled with instances of bl2_obj_set_trans() to clear the bit.
- Added Jed to CREDITS file.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 22 18:15:41 2013 -0600
Replaced banded/packed BLAS2 stubs with f2c code.
Details:
- Retired the blas2blis wrappers that simply called abort with a "not yet
implemented" message. This includes all of the level-2 banded and packed
routines.
- Replaced the aforementioned with the corresponding netlib implementations
having been run through f2c (with some customization).
- Added directories named 'attic' to build/gen-make-frags/ignore_list.

Moved Fortran name-mangling macro to bl2_config.h.
Details:
- Moved the Fortran-77 name-mangling macros from bl2_blas_macro_defs.h to the
configuration directory (bl2_config.h, specifically) given that it can be
expected to be tweaked by some developers.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 22 12:11:24 2013 -0600
Implemented blas2blis compatibility layer.
Details:
- Added the blas2blis compatibility layer, located in frame/compat. This
includes virtually all of the BLAS, including banded and packed level-2
operations.
- Defined bl2_init_safe(), bl2_finalize_safe(). The former allows a conditional
initialization, which stores the "exit status" in an err_t, which is then
read by the latter function to determine whether finalization should actually
take place.
- Added calls to bl2_init_safe(), bl2_finalize_safe() to all level-2 and
level-3 BLAS-like wrappers.
- Added configuration option to instruct BLIS to remain initialized whenever
it automatically initializes itself (via bl2_init_safe()), until/unless the
application code explicitly calls bl2_finalize().
- Added INSERT_GENTFUNC* and INSERT_GENTPROT* macros to facilitate type
templatization of blas2blis wrappers.
- Defined level-0 scalar macro bl2_??swaps().
- Defined level-1v operation bl2_swapv().
- Defined some "Fortran" types to bl2_type_defs.h for use with BLAS
wrappers.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 21 12:00:17 2013 -0600
Fixed some scalar types in BLAS-like Herm APIs.
Details:
- Some of the scalars of Hermitian operations, such as alpha in her,
alpha and beta in herk, and beta in her2k, need to be real. These
arguments were typed incorrectly as the complex types. This has been
fixed. Note the issue was only present in the BLAS-like APIs for
these operations (not the native object-based interfaces).

Changed API of packm_init_pack() to use blksz_t.
Details:
- Changed the interface of packm_init_pack() so that mult_m and mult_n
are passed in as type blksz_t* instead of dim_t.
- Make similar change for packv_init_pack().

Minor changes to lower levels of scalm and setm.
Details:
- Removed diagx parameter from lower-level interfaces of scalm.
- Modified scalm_basic_check() to expect an object with a nonunit diagonal.
- Changed setm_unb_var1() so that having an implicit unit diagonal results
in only the strictly lower or upper triangle of the matrix being modified.

Updated beta == zero semantics of mulsc.
Details:

operation that needed updating.
- Added Devin to CREDITS file.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 14 10:18:00 2013 -0600
Removed some calls to setv() in test modules.
Details:
- Removed calls to setv() in test modules whose sole purpose was to
initialize vectors to zero to ensure that nan's and inf's would not
taint the computation. Now that beta == zero semantics have been
updated to clear the output operand (when beta is zero), rather than
multiply against it, these setv() calls are no longer needed.
commit e6ac623a902f776c42f85eadbf76996d9770a0db
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 13 18:44:59 2013 -0600
Properly implemented beta == 0 semantics.
Details:
- Changed name of set0 and set0_mxn macros to set0s and set0s_mxn,
respectively.
- Added code to the following operations that sets the output operand to
zero if the corresponding scalar is zero (rather than performing the
floating-point multiply, or in the case of setv, copying the value).
This will prevent nan's and inf's from creeping into results from
uninitialized memory.

Fixed stale interface to packm_unb_var1().
Details:
- Removed the control tree from the interface to packm_unb_var1(), which
I meant to do when it was un-deprecated.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 13 13:21:00 2013 -0600
Un-deprecated packm_unb_var1.c (needed by l2 ops).
Details:
- Added bl2_packm_unb_var1() back into the mix once I realized that level-2
operations still need this routine for packing matrices. Now, whether
level-2 operations should be packing matrices to begin with is another
matter. But this fixes the segmentation fault one would have gotten when
running bl2_gemv() on a general stride matrix.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 12 18:39:35 2013 -0600
Removed cntl tree usage from packm implementation.
Details:
- Added new fields to obj_t info field:
- invert_diag
- pack_order_if_upper
- pack_order_if_lower
These fields allow packm_init() to embed information that begins
in the control tree into the object so that the packm implementation
does not need to use control trees at all. This is being done to aid
Bryan's DxT code generation.
- Added macros that operate on above fields.
- Changed packm_init(), packm_blk_var2(), and packm_blk_var3() according
to above changes.
- Made similar (but much simpler) changes to packv.
- Deprecated packm_blk_var1(), packm_unb_var1(), and packm_densify().
These were part of prototype implementations and are no longer needed.

commit 768fcebaa8be0eb936a6e7a02cd8a19438c79d99 (tag: 0.0.2)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Feb 11 13:20:44 2013 -0600
Added unified test suite, and many fixes.
Details:
- Added a highly configurable, unified test suite.
- Removed DUPB configuration constant from bl2_kernel.h and macro-kernel
header files. Now, instead, DUPB is computed as (NDUP != 1) within each
macro-kernel. This fixes a bug in trmm/trsm whereby bp was indexed into
incorrectly when DUPB was set to FALSE but the NDUP was still non-unit.
By encoding both pieces of information into one constant in _kernel.h,
it seems somewhat less likely others will encounter this bug in the
future.
- Added level-2 cache blocksizes to _kernel.h for reference configuration,
and defined blocksizes in _cntl.c files to these default values.
- Changed semantics of her2k and syr2k such that these operations no longer
expect the B matrix to already be conjugate-transposed (or just transposed
for syr2k). However, these semantics are preserved for the internal
mechanics of the implementations, including the internal back-end and all
blocked variants.
- Inserted checks for real-valued alpha and beta for herk/her2k and herk,
respectively.
- Relaxed general object structure constraints in _basic_check() for gemv, ger.
- Changed her front-end to NOT copy-cast to real projection; instead, this is
replaced by selecting either the real part or both parts within the unblocked
algorithm implementation, depending on the value of conjh.
- Added conjh to all _check routines for her so that the code knows when to
verify that alpha has an imaginary component equal to zero (for her, but
not syr).
- Changed control tree for her to forgo packing.
- Added unit diagonal support to fnormm.
- Redefined real versions of abval2s macros in terms of fabs(), fabsf().
- Redefined complex versions of sqrt2s macros using the actual "complex square
root" formula.
- Created new level-0 object-based routines, suffixed with "sc" (for "scalar").
- Defined new level-1v, -1d, and -1m versions of add and sub operations
(two-operand add and subtract).
- Added new scalar macros:
- getris: acquire real and imaginary components.
- setris: set real and imaginary components.
- addjs: addition with conjugated x.
- subjs: subtraction with conjugated x.
- Defined new utility operations:
- absumv: element-wise sum of absolute values for vector elements.
- absumm: element-wise sum of absolute values for matrix elements.
- mkherm: convert existing matrix to Hermitian.
- mksymm: convert existing matrix to symmetric.
- mktrim: convert existing matrix to triangular.
- Added various error checking routines.
- Added bl2_clock_min_diff(), which is used to more cleanly measure the
wall clock time of a code block.
- Added general stride support to bl2_obj_alloc_buffer().
- Added bl2_obj_init_scalar().
- Updated parameter mapping in bl2_param_map.c.
- Added support for queriable version string.
- Fixed a bug in the her2k macro-kernels (which currently are simply
implemented in terms of two invocations of herk) whereby beta was being
applied to both the first and second rank-k updates, rather than only
the first.
- Fixed a bug in trmm/trsm whereby transpose and right side cases were not
properly implemented due to erroneous assumptions regarding aliasing and
root objects.
- Fixed a bug in the upper triangular trsm macro-kernel in which the wrong
MR x NR block of B was being updated.
- Fixed a bug in the inverts macro in the double real case whereby the
value was typecast to float before inversion. This affected non-unit cases
of dtrsm.
- Fixed a bug in the reference kernels for gemmtrsm whereby the minus one
constant was being applied incorrectly.
- Fixed a bug in the overall treatment of non-unit alpha for trsm. The code
now mimics the rank-k strategy of gemm, whereby alpah is applied during
the first iteration of variant 3, with BLIS_ONE passed in instead for
subsequent iterations. This also required passing alpha into the macro-
kernels as well as the fused gemmtrsm micro-kernels.
- Fixed a bug in trsm_u_blk_var1 whereby the gemm macro-kernel was being
called for blocks strictly above the diagonal. While this sounds good in
theory, this cannot be done because gemm_ker_var2 expects row panels of
A to be packed from top to bottom, while for trsm_u, A is actually packed
from bottom to top due to the reverse (BR->TL) nature of the algorithm.
- Fixed a bug in packm_cxk() whereby panel packings with unit panel
dimensions were mishandled due to incorrect arguments to the copyv kernel.
Also changed the copyv kernel invocation to scal2v so that these edge
cases are properly handled when scaling is requested.
- Fixed a bug in packv_int() whereby an uninitialized object is passed in
instead of the source object.
- Fixed a bug whereby level-2 code could allocate memory dynamically via
bl2_malloc() and then attempt to free it via bl2_mm_release(). Also fixed
a potential future bug whereby a mem_t object that is actually no longer
"allocated" from the static pool is mistaken for being allocated due to
failure to NULLify the buffer when the block was most recently released.
- Fixed a bug in bl2_acquire_mpart_*() whreby the uplo field was mistakenly
toggled when the requested subpartition needed to be "reflected" due to it
residing in an unstored region.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Dec 20 17:07:50 2012 -0600
Defined Frobenius norm operations.
Details:
- Added level-0 grabis macro operation to grab imaginary component of one
variable and copy it to the real component of another variable.
- Defined sumsqv operation, which computes the sum of the absolute squares
of the elements of a vector. This implementation is modeled after ?lassq
in netlib LAPACK.
- Defined fnormv and fnormm operations, which compute the Frobenius norm on
vectors and matrices, respectively. These operations are treated as one-
operand operations where the output norm value is the real projection of
the datatype of the input operand. Both operations are implemented in terms
of sumsqv.

Fixed harmless macro bug in level-1m operations.
Details:
- Fixed some inconsistent usage of n_iter_max and n_iter in the two
bl2_set_dims_incs_uplo_[12]m macros. The right thing ended up happening
despite the bug, which is why I had not discovered it until now.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Dec 18 15:07:36 2012 -0600
Renamed x86,x86_64 kernels to indicate 'd' fusing.
Details:
- Renamed x86 and x86_64 kernels to contain a 'd' before the fusing shape
to emphasize that the fusing shape is not for all datatype instances, but
rather just for one (that of double-precision real). Other fusing shapes
would be proportional to their precision and domain "byte footprints".
- Corresponding changes to config/clarksville/bl2_kernel.h.
commit 6fbbdd4e194d06096ad08c5db61127be338067db

More tweaks to _config.h, _kernel.h; smem tweaks.
Details:
- Moved kernel-related definitions form bl2_config.h to bl2_kernel.h.
- Replaced #define of _GNU_SOURCE with #define of _POSIX_C_SOURCE. This
accomplishes the same thing (enabling posix_memalign()) without enabling
all of the GNU extensions we don't need.
- Defined the size of the static memory pool in terms of MC, KC, and NC,
as well as two new constants that determine how many MCxKC blocks and
how many KCxNC blocks should be allocated (defined in bl2_config.h).
- In the case of static memory pool exhaustion, replaced the generic
bl2_abort() with a specific error code call.

kernel size is requested. (Thanks to Tyler for finding this bug.)
- Updated bl2_kernel.h to contain new _KERNEL definitions, according
to above changes, for 'reference' and 'clarksville' configurations.
- Updated CHANGELOG.
- Removed "output*.m" from .gitignore.

string and updating 'version' file accordingly. (If .git directory is
not present, then it is assumed this copy of BLIS is a downloaded
release, in which case 'version' file is left unchanged.)
- Added invocation of update-version-file.sh to configure script.
