Details:
- Adjusted the method by which micropanels are assigned to threads in
the 2nd (jr) and 1st (ir) loops around the microkernel to (mostly)
employ contiguous "slab" partitioning rather than interleaved (round
robin) partitioning. The new partitioning schemes and related details
for specific families of operations are listed below:
- gemm: slab partitioning.
- herk: slab partitioning for region corresponding to non-triangular
region of C; round robin partitioning for triangular region.
- trmm: slab partitioning for region corresponding to non-triangular
region of B; round robin partitioning for triangular region.
(NOTE: This affects both left- and right-side macrokernels:
trmm_ll, trmm_lu, trmm_rl, trmm_ru.)
- trsm: slab partitioning.
(NOTE: This only affects only left-side macrokernels trsm_ll,
trsm_lu; right-side macrokernels were not touched.)
Also note that the previous macrokernels were preserved inside of
the 'other' directory of each operation family directory (e.g.
frame/3/gemm/other, frame/3/herk/other, etc).
- Updated gemm macrokernel in sandbox/ref99 in light of above changes
and fixed a stale function pointer type in blx_gemm_int.c
(gemm_voft -> gemm_var_oft).
- Added standalone test drivers in test/3m4m for herk, trmm, and trsm
and minor changes to test/3m4m/Makefile.
- Updated the arguments and definitions of bli_*_get_next_[ab]_upanel()
and bli_trmm_?_?r_my_iter() macros defined in bli_l3_thrinfo.h.
- Renamed bli_thread_get_range*() APIs to bli_thread_range*().
