Details:
- Updated the BLAS compatibility layer for level-3 operations so that
the corresponding BLIS object API is called directly rather than first
calling the typed BLIS API. The previous code based on the typed BLIS
API calls is still available in a deactivated cpp macro branch, which
may be re-activated by #defining BLIS_BLAS3_CALLS_TAPI. (This does not
yet correspond to a configure option. If it seems like people might
want to toggle this behavior more regularly, a configure option can be
added in the future.)
- Updated the BLIS typed API to statically "pre-initialize" objects via
new initializor macros. Initialization is then finished via calls to
static functions bli_obj_init_finish_1x1() and bli_obj_init_finish(),
which are similar to the previously-called functions,
bli_obj_create_1x1_with_attached_buffer() and
bli_obj_create_with_attached_buffer(), respectively. (The BLAS
compatibility layer updates mentioned above employ this new technique
as well.)
- Transformed certain routines in bli_param_map.c--specifically, the
ones that convert netlib-style parameters to BLIS equivalents--into
static functions, now in bli_param_map.h. (The remaining three classes
of conversation routines were left unchanged.)
- Added the aforementioned pre-initializor macros to bli_type_defs.h.
- Relocated bli_obj_init_const() and bli_obj_init_constdata() from
bli_obj_macro_defs.h to bli_type_defs.h.
- Added a few macros to bli_param_macro_defs.h for testing domains for
real/complexness and precisions for single/double-ness.
Details:
- Minor updates to matlab graph-generating scripts.
- Added a plot_all.m script that is more of a scratchpad for copying and
pasting function invocations into matlab to generate plots that are
presently of interest to us.
Details:
- Changed -funsafe-loop-optimizations (re-)introduced in 7690855 for
make_defs.mk files' CRVECFLAGS to -funsafe-math-optimizations (to
account for a miscommunication in issue #300). Thanks to Dave Love
for this suggestion and Jeff Hammond for his feedback on the topic.
Details:
- Restored use of -funsafe-loop-optimizations in the definitions of
CRVECFLAGS (when using gcc), but only for sub-configurations (and
not configuration families such as amd64, intel64, and x86_64).
This more or less reverts 5190d05 and 6cf1550.
Details:
- Added -mno-tbm -mno-xop -mno-lwp to CKVECFLAGS in bulldozer,
piledriver, steamroller, and excavator configurations to explicitly
disable AMD's bulldozer-era TBM, XOP, and LWP instruction sets in an
attempt to fix the invalid instruction error that has plagued Travis
CI builds since 6a014a3. Thanks to Devin Matthews for pointing out
that the offending instruction was part of TBM (issue #300).
- Restored -O3 to piledriver configuration's COPTFLAGS.
Details:
- Removed -funsafe-loop-optimizations from the configuration families
affected by 6a014a3, specifically: intel64, amd64, and x86_64.
This is part of an attempt to debug why the sde, as executed by
Travis CI, is crashing via the following error:
TID 0 SDE-ERROR: Executed instruction not valid for specified chip
(ICELAKE): 0x9172a5: bextr_xop rax, rcx, 0x103
Details:
- Per Dave Love's recommendation in issue #300, this commit defines
COPTFLAGS := -03
and
CRVECFLAGS := $(CKVECFLAGS) -funsafe-loop-optimizations
in the make_defs.mk for all Intel- and AMD-based configurations.
Updated copyright information for kernels/zen/bli_trsm_small.c file
Removed separate kernels for zen2 architecture
Instead added threshold conditions in zen kernels both for ROME and NAPLES
Change-Id: Ifd715731741d649b6ad16b123a86dbd6665d97e5
config/zen/bli_family_zen.h: deleted macro BLIS_ENBLE_ZEN_BLOCK_SIZES
config/zen/make_defs.mk: removed compiler flag -mno-avx256-split-unaligned-store
frame/base/bli_cpuid.c: ROME family is 17H but model # is from 0x30H.
test/test_gemm.c - commented out #define FILE_IN_OUT (some compilation error when BLIS is configured as amd64)
Now we can use single configuration has ./configure amd64 - this will work both for ROME & Naples

A Macro 'FILE_IN_OUT" is defined to read input parameters from a csv file.
Format for input file:
Each line defines a gemm problem with following parameters: m k n cs_a cs_b cs_c
The operation always implemented is C = C - A*B and column-major format.
When macro is disabled - it reverts back to original implementation.
Usage: ./test_gemm_<mkl/blis/openblas>.x input.csv output.csv
GEMM is called through BLAS interface
For BLIS - the test application also prints either 'S' indicating small gemm routine or 'N' - conventional BLIS gemm
for MKL/OpenBLAS - ignore this character
