commit 898614a555ea0aa7de4ca07bb3cb8f5708b6a002 (HEAD -> master, tag: 0.2.0)

Version file update (0.2.0)
commit 537a1f4f85ce1aa008901857cb3182e6b4546d7f
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Apr 11 17:21:28 2016 -0500
Implemented runtime contexts and reorganized code.
Details:
- Retrofitted a new data structure, known as a context, into virtually
all internal APIs for computational operations in BLIS. The structure
is now present within the type-aware APIs, as well as many supporting
utility functions that require information stored in the context. User-
level object APIs were unaffected and continue to be "context-free,"
however, these APIs were duplicated/mirrored so that "context-aware"
APIs now also exist, differentiated with an "_ex" suffix (for "expert").
These new context-aware object APIs (along with the lower-level, type-
aware, BLAS-like APIs) contain the the address of a context as a last
parameter, after all other operands. Contexts, or specifically, cntx_t
object pointers, are passed all the way down the function stack into
the kernels and allow the code at any level to query information about
the runtime, such as kernel addresses and blocksizes, in a thread-
friendly manner--that is, one that allows thread-safety, even if the
original source of the information stored in the context changes at
run-time; see next bullet for more on this "original source" of info).
(Special thanks go to Lee Killough for suggesting the use of this kind
of data structure in discussions that transpired during the early
planning stages of BLIS, and also for suggesting such a perfectly
appropriate name.)
- Added a new API, in frame/base/bli_gks.c, to define a "global kernel
structure" (gks). This data structure and API will allow the caller to
initialize a context with the kernel addresses, blocksizes, and other
information associated with the currently active kernel configuration.
The currently active kernel configuration within the gks cannot be
changed (for now), and is initialized with the traditional cpp macros
that define kernel function names, blocksizes, and the like. However,
in the future, the gks API will be expanded to allow runtime management
of kernels and runtime parameters. The most obvious application of this
new infrastructure is the runtime detection of hardware (and the
implied selection of appropriate kernels). With contexts in place,
kernels may even be "hot swapped" at runtime within the gks. Once
execution enters a level-3 _front() function, the memory allocator will
be reinitialized on-the-fly, if necessary, to accommodate the new
kernels' blocksizes. If another application thread is executing with
another (previously loaded) kernel, it will finish in a deterministic
fashion because its kernel information was loaded into its context
before computation began, and also because the blocks it checked out
from the internal memory pools will be unaffected by the newer threads'
reinitialization of the allocator.
- Reorganized and streamlined the 'ind' directory, which contains much of
the code enabling use of induced methods for complex domain matrix
multiplication; deprecated bli_bsv_query.c and bli_ukr_query.c, as
those APIs' functionality is now mostly subsumed within the global
kernel structure.
- Updated bli_pool.c to define a new function, bli_pool_reinit_if(),
that will reinitialize a memory pool if the necessary pool block size
has increased.
- Updated bli_mem.c to use bli_pool_reinit_if() instead of
bli_pool_reinit() in the definition of bli_mem_pool_init(), and placed
usage of contexts where appropriate to communicate cache and register
blocksizes to bli_mem_compute_pool_block_sizes().
- Simplified control trees now that much of the information resides in
the context and/or the global kernel structure:
- Removed blocksize object pointers (blksz_t*) fields from all control
tree node definitions and replaced them with blocksize id (bszid_t)
values instead, which may be passed into a context query routine in
order to extract the corresponding blocksize from the given context.
- Removed micro-kernel function pointers (func_t*) fields from all
control tree node definitions. Now, any code that needs these function
pointers can query them from the local context, as identified by a
level-3 micro-kernel id (l3ukr_t), level-1f kernel id, (l1fkr_t), or
level-1v kernel id (l1vkr_t).
- Removed blksz_t object creation and initialization, as well as kernel
function object creation and initialization, from all operation-
specific control tree initialization files (bli_*_cntl.c), since this
information will now live in the gks and, secondarily, in the context.
- Removed blocksize multiples from blksz_t objects. Now, we track
blocksize multiples for each blocksize id (bszid_t) in the context
object.
- Removed the bool_t's that were required when a func_t was initialized.
These bools are meant to allow one to track the micro-kernel's storage
preferences (by rows or columns). This preference is now tracked
separately within the gks and contexts.
- Merged and reorganized many separate-but-related functions into single
files. This reorganization affects frame/0, 1, 1d, 1m, 1f, 2, 3, and
util directories, but has the most obvious effect of allowing BLIS
to compile noticeably faster.
- Reorganized execution paths for level-1v, -1d, -1m, and -2 operations
in an attempt to reduce overhead for memory-bound operations. This
includes removal of default use of object-based variants for level-2
operations. Now, by default, level-2 operations will directly call a
low-level (non-object based) loop over a level-1v or -1f kernel.
- Converted many common query functions in blk_blksz.c (renamed from
bli_blocksize.c) and bli_func.c into cpp macros, now defined in their
respective header files.
- Defined bli_mbool.c API to create and query "multi-bools", or
heterogeneous bool_t's (one for each floating-point datatype), in the
same spirit as blksz_t and func_t.
- Introduced two key parameters of the hardware: BLIS_SIMD_NUM_REGISTERS
and BLIS_SIMD_SIZE. These values are needed in order to compute a third
new parameter, which may be set indirectly via the aforementioned
macros or directly: BLIS_STACK_BUF_MAX_SIZE. This value is used to
statically allocate memory in macro-kernels and the induced methods'
virtual kernels to be used as temporary space to hold a single
micro-tile. These values are now output by the testsuite. The default
value of BLIS_STACK_BUF_MAX_SIZE is computed as
"2 * BLIS_SIMD_NUM_REGISTERS * BLIS_SIMD_SIZE".
- Cleaned up top-level 'kernels' directory (for example, renaming the
embarrassingly misleading "avx" and "avx2" directories to "sandybridge"
and "haswell," respectively, and gave more consistent and meaningful
names to many kernel files (as well as updating their interfaces to
conform to the new context-aware kernel APIs).
- Updated the testsuite to query blocksizes from a locally-initialized
context for test modules that need those values: axpyf, dotxf,
dotxaxpyf, gemm_ukr, gemmtrsm_ukr, and trsm_ukr.
- Reformatted many function signatures into a standard format that will
more easily facilitate future API-wide changes.
- Updated many "mxn" level-0 macros (ie: those used to inline double loops
for level-1m-like operations on small matrices) in frame/include/level0
to use more obscure local variable names in an effort to avoid variable
shaddowing. (Thanks to Devin Matthews for pointing these gcc warnings,
which are only output using -Wshadow.)
- Added a conj argument to setm, so that its interface now mirrors that
of scalm. The semantic meaning of the conj argument is to optionally
allow implicit conjugation of the scalar prior to being populated into
the object.
- Deprecated all type-aware mixed domain and mixed precision APIs. Note
that this does not preclude supporting mixed types via the object APIs,
where it produces absolutely zero API code bloat.

Included missing blas2blis integer def to CBLAS.
Details:
- Added #include "bli_config_macro_defs" to all cblas_*.c files in
compat/cblas/src. This has the effect of defining
BLIS_BLAS2BLIS_INT_TYPE_SIZE to the default value if bli_config.h does
not define it. Thanks to Tony Kelman for reporting this bug.
- In cblas_i?amax.c, changed the type of the variable 'iamax' from 'int'
to 'f77_int'. This eliminates a compiler warning and a potential
runtime bug and/or crash when the size of an int differs from the size
of f77_int (as determined by BLIS_BLAS2BLIS_INT_TYPE_SIZE).

- simplifies how buffers are sized when requested BLIS-allocated
objects,
- re-consolidates bli_adjust_strides_*() into one function, and
- defines 'restrict' keyword as a "nothing" macro for C++ and pre-C99
environments.

Fixed unimplemented case in core2 sgemm ukernel.
Details:
- Implemented the "beta == 0" case for general stride output for the
dunnington sgemm micro-kernel. This case had been, up until now,
identical to the "beta != 0" case, which does not work when the
output matrix has nan's and inf's. It had manifested as nan residuals
in the test suite for right-side tests of ctrsm4m1a. Thanks to Devin
Matthews for reporting this bug.

Fixed minor bugs for uncommon obj_create cases.
Details:
- Separated bli_adjust_strides() into _alloc() and _attach() flavors so
that the latter can avoid a test performed by the former, in which the
rs and cs are overridden and set to zero if either matrix dimension is
zero. Actually, we also disable this overridding behavior, even for the
_alloc() case, since keeping the original strides (probably) does not
hurt anything. The original code has been kept commented-out, though,
in case an unintended consequence is later discovered.
- Fixed a typo in an error check for general stride cases where rs == cs.

Fixed imaginary bug in quadratic partitioning code.
Details:
- Fixed a bug in the relatively new quadratic partitioning code that,
under the right conditions, would perform sqrt() on a negative value.
If the solution is imaginary, we discard it and use an alternate
partition width that assumes no diagonal intersection. That alternate
width is actually already computed, so, the fix was quite simple.
Thanks to Devangi Parikh for reporting this bug.

Laid groundwork for runtime memory pool resizing.
Details:
- Changed bli_pool_finalize() so that the freeing begins with the block
at top_index instead of block 0. This allows us to use the function
for terminal finalization as well as temporary cleanup prior to
reinitialization. Also, clear the pool_t struct upon _pool_finalize()
in case it is called in the terminal case with some blocks still
checked out to threads (in which case the threads will see the new
block size as 0 and thus release the block as intended).
- Added bli_pool_reinit(), which calls _pool_finalize() followed by
_pool_init() with new parameters.
- Added bli_mem_reinit(), which is based on bli_pool_reinit().
- Added new wrapper, _mem_compute_pool_block_sizes(), which calls
_mem_compute_pool_block_sizes_dt().
- Updated bli_mem_release() so that the pblk_t is freed, via
_pool_free_block(), if the block size recorded in the mem_t at the
time the pblk_t was acquired is now different from the value in the
pool_t.

Fixed obscure 3m1/4m1a bugs in trmm[3] and trsm.
Details:
- Fixed a family of bugs in the triangular level-3 operations for
certain complex implementations (3m1 and 4m1a) that only manifest if
one of the register blocksizes (PACKMR/PACKNR, actually) is odd:
- Fixed incorrect imaginary stride computation in bli_packm_blk_var2()
for the triangular case.
- Fixed the incorrect computation of imaginary stride, as stored in
the auxinfo_t struct in trmm and trsm macro-kernels.
- Fixed incorrect pointer arithmetic in the trsm macro-kernels in the
cases where the the register blocksize for the triangular matrix is
odd. Introduced a new byte-granular pointer arithmetic macro,
bli_ptr_add(), that computes the correct value.
- Added cpp macro to bli_macro_defs.h for typeof() operator, defined in
terms of __typeof__, which is used by bli_ptr_add() macro.
- Disabled the row- vs. column-storage optimization in bli_trmm_front()
for singleton problems because the inherent ambiguity of whether a
scalar is row-stored or column-stored causes the wrong parameter
combination code to be executed (by dumb luck of our checking for
row storage first).
- Added commented-out debugging lines to 3m1/4m1a and reference
micro-kernels, and trsm_ll macro-kernel.

Load balance thread ranges for arbitrary diagonals.
Details:
- Expanded/updated interface for bli_get_range_weighted() and
bli_get_range() so that the direction of movement is specified in the
function name (e.g. bli_get_range_l2r(), bli_get_range_weighted_t2b())
and also so that the object being partitioned is passed instead of an
uplo parameter. Updated invocations in level-3 blocked variants, as
appropriate.
- (Re)implemented bli_get_range_*() and bli_get_range_weighted_*() to
carefully take into account the location of the diagonal when computing
ranges so that the area of each subpartition (which, in all present
level-3 operations, is proportional to the amount of computation
engendered) is as equal as possible.
- Added calls to a new class of routines to all non-gemm level-3 blocked
variants:
bli_<oper>_prune_unref_mparts_[mnk]()
where <oper> is herk, trmm, or trsm and [mnk] is chosen based on which
dimension is being partitioned. These routines call a more basic
routine, bli_prune_unref_mparts(), to prune unreferenced/unstored
regions from matrices and simultaneously adjust other matrices which
share the same dimension accordingly.
- Simplified herk_blk_var2f, trmm_blk_var1f/b as a result of more the
new pruning routines.
- Fixed incorrect blocking factors passed into bli_get_range_*() in
bli_trsm_blk_var[12][fb].c
- Added a new test driver in test/thread_ranges that can exercise the new
bli_get_range_*() and bli_get_range_weighted_*() under a range of
conditions.
- Reimplemented m and n fields of obj_t as elements in a "dim"
array field so that dimensions could be queried via index constant
(e.g. BLIS_M, BLIS_N). Adjusted/added query and modification
macros accordingly.
- Defined mdim_t type to enumerate BLIS_M and BLIS_N indexing values.
- Added bli_round() macro, which calls C math library function round(),
and bli_round_to_mult(), which rounds a value to the nearest multiple
of some other value.
- Added miscellaneous pruning- and mdim_t-related macros.
- Renamed bli_obj_row_offset(), bli_obj_col_offset() macros to
bli_obj_row_off(), bli_obj_col_off().

Fixed minor alignment ambiguity bug in bli_pool.c.
Details:
- Fixed a typecasting ambiguity in bli_pool_alloc_block() in which
pointer arithmetic was performed on a void* as if it were a byte
pointer (such as char*). Some compilers may have already been
interpreting this situation as intended, despite the sloppiness.
Thanks to Aleksei Rechinskii for reporting this issue.
- Redefined pointer alignment macros to typecast to uintptr_t instead of
siz_t.
