commit 768fcebaa8be0eb936a6e7a02cd8a19438c79d99 (HEAD, tag: 0.0.2, origin/master, master)
commit e7d41229d3b1674e74f47d7f29fae004a745201a (HEAD, tag: 0.0.4, origin/master, master)
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.
commit 1e76cae00cb0a04544aaae1ade878686b238d283
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 15 12:21:42 2013 -0500
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.
commit c95c270eba91ae4efc26603beddfd0292caa919b
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.
commit e99281a0f41d482fddeffa239bfc8e13e6d13d4b
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Mar 7 14:00:10 2013 -0600
Fixed test suite flop formulas for ops with side.
Details:
- Fixed incorrect flop counts in test suite modules for hemm, symm, trmm,
trmm3, and trsm.
- Comment updates in herk macro-kernels.
commit ef8cbfc44dd620fdcbdb51cdb173217194bebe31
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sat Mar 2 12:47:06 2013 -0600
Added "version" to .gitignore.
Details:
- Added "version" to .gitignore file so that the file does not show up when
running 'git status', or accidentally get pulled into the index when
running 'git add' or 'git add --all'.
commit e9e0747c2f6c178f53ac46ab794acbb7b8c4fea8
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sat Mar 2 12:43:54 2013 -0600
Removed version file from version control.
Details:
- Removed version file from version control to prevent git errors that occur
when trying to pull new commits.
commit bb612f864e9c17dd9805e9446840f02259619469
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Mar 1 12:55:42 2013 -0600
Updated behavior of bl2_obj_induce_trans() macro.
Details:
- 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.
commit f24e29b789e7314764a818ceb3063126936c986f
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.
commit 1454c1a14207766dfed372b8e38b47fa384f5198
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 22 12:38:45 2013 -0600
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.
commit ede75693e5a36c6006087c4a7df834175b604504 (tag: 0.0.3)
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.
commit 995edf43e21c1868732dbdd7fee14b08730218bd
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 21 14:30:50 2013 -0600
Updated version file. (Forgot to in prev commit).
commit e823b08aaf7b65ecc6ddc30570709ea8a4b52aa7
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).
commit 5ece050a669e74ba4a711d1d4669239d22d45642
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 20 15:50:54 2013 -0600
Updated version file. (Forgot to in prev commit).
commit f243034b8b430d4684680ea8eddfd246e73fefc0
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 20 14:11:36 2013 -0600
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().
commit da0c22f24107be9f33e0ea2dae52e5534b1fd0e5
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Feb 15 09:59:48 2013 -0600
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.
commit 2c836adadcd2a7d7f217033ac4d7fcad03d5bd55
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Feb 14 10:42:56 2013 -0600
Updated beta == zero semantics of mulsc.
Details:
- Updated beta == zero semantics of mulsc. Hopefully this is the last
operation that needed updating.
- Added Devin to CREDITS file.
commit 722b66c7dcaaaa1b109e7c8b1d53fd71a9af8240
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.

commit aedccbc85d491e41711a0c6eb0d246d8700a199a
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Feb 13 18:29:53 2013 -0600
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.
commit c23135669f7a8a545e2e11ef559bf284be8bc65c
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.
commit cf49e35f9819f9d93ebdca4703ade5abab28f6f6
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 eb139ae256651af7820b93ef982626180195b87f
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 12 12:39:30 2013 -0600
Replaced bl2_abs() with _fabs() where appropriate.
commit 474bac30c99928f9e87315972bcb45c632c0b7ec
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 12 12:23:48 2013 -0600
Removed level-0 macros projrs, grabis.
Details:
- Replaced instances of projrs and grabis macros with newer,
more general-purpose getris.
commit 03a260a457c8964e4603a655cee0d40ac17affba
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Feb 12 11:45:34 2013 -0600
Restored executable permissions to scripts.
Details:
- Restored executable (0755) permissions to scripts that were touched by
the recursive sed script that updated the copyright headers in the
previous commit.
