Details:
- Moved edge-case handling into the gemm microkernel. This required
changing the microkernel API to take m and n dimension parameters.
This required updating all existing gemm microkernel function pointer
types, function signatures, and related definitions to take m and n
dimensions. We also updated all existing kernels in the 'kernels'
directory to take m and n dimensions, and implemented edge-case
handling within those microkernels via a collection of new C
preprocessor macros defined within bli_edge_case_macro_defs.h. Also
removed the assembly code that formerly would handle general stride
IO on the microtile, since this can now be handled by the same code
that does edge cases.
- Pass the obj_t.ker_fn (of matrix C) into bli_gemm_cntl_create() and
bli_trsm_cntl_create(), where this function pointer is used in lieu of
the default macrokernel when it is non-NULL, and ignored when it is
NULL.
- Re-implemented macrokernel in bli_gemm_ker_var2.c to be a single
function using byte pointers rather that one function for each
floating-point datatype. Also, obtain the microkernel function pointer
from the .ukr field of the params struct embedded within the obj_t
for matrix C (assuming params is non-NULL and contains a non-NULL
value in the .ukr field). Communicate both the gemm microkernel
pointer to use as well as the params struct to the microkernel via
the auxinfo_t struct.
- Defined gemm_ker_params_t type (for the aforementioned obj_t.params
struct) in bli_gemm_var.h.
- Retired the separate _md macrokernel for mixed datatype computation.
We now use the reimplemented bli_gemm_ker_var2() instead.
- Updated gemmt macrokernels to pass m and n dimensions into microkernel
calls.
- Removed edge-case handling from trmm and trsm macrokernels.
- Moved most of bli_packm_alloc() code into a new helper function,
bli_packm_alloc_ex().
- Fixed a typo bug in bli_gemmtrsm_u_template_noopt_mxn.c.
- Added test/syrk_diagonal and test/tensor_contraction directories with
associated code to test those operations.
Details:
- Added missing license header to bli_pwr9_asm_macros_12x6.h.
- Reverted temporary changes to various files in 'test' and 'testsuite'
directories.
- Moved testsuite/jobscripts into testsuite/old.
- Minor whitespace/comment changes across various files.
Implemented and registered power9 dgemm ukernel.
Details:
- Implemented 12x6 dgemm microkernel for power9. This microkernel
assumes that elements of B have been duplicated/broadcast during the
packing step. The microkernel uses a column orientation for its
microtile vector registers and thus implements column storage and
general stride IO cases. (A row storage IO case via in-register
transposition may be added at a future date.) It should be noted that
we recommend using this microkernel with gcc and *not* xlc, as issues
with the latter cropped up during development, including but not
limited to slightly incompatible vector register mnemonics in the GNU
extended inline assembly clobber list.
