5a720cf9ca Re-enable loop unrolling in trmv and remove the scary warning 
fixes #1748 as that half of the fix for #1332 appears to have been an overreaction on my part.

b28f75cd7e set GEMM_PREFERED_SIZE for HASWELL 
Haswell likes a GEMM_PREFERED_SIZE of 16 to improve the split that the
threading code does to make it a nice multiple of the SIMD kernel size

0586899a10 Use sgemm_ncopy_4_skylakex.c also for Haswell 
sgemm_ncopy_4_skylakex.c uses SSE transpose operations where the
real perf win happens; this also works great for Haswell.

This gives double digit percentage gains on small and skinny matrices

00dc09ad19 Use the skylake sgemm beta code also for haswell 
with a few small changes it's possible to use the skylake sgemm code
also for haswell, this gives a modest gain (10% range) for smallish
matrixes but does wonders for very skinny matrixes

Add a "sgemm direct" mode for small matrixes
 2018-12-13 19:08:14 +01:00
Arjan van de Ven
cdc668d82b Add a "sgemm direct" mode for small matrixes 
OpenBLAS has a fancy algorithm for copying the input data while laying
it out in a more CPU friendly memory layout.

This is great for large matrixes; the cost of the copy is easily
ammortized by the gains from the better memory layout.

But for small matrixes (on CPUs that can do efficient unaligned loads) this
copy can be a net loss.

This patch adds (for SKYLAKEX initially) a "sgemm direct" mode, that bypasses
the whole copy machinary for ALPHA=1/BETA=0/... standard arguments,
for small matrixes only.

What is small? For the non-threaded case this has been measured to be
in the M*N*K = 28 * 512 * 512 range, while in the threaded case it's
less, around M*N*K = 1 * 512 * 512
