Arjan van de Ven 795285c587 Fix thinko in skylake beta handling 
casting ints is cheaper but it has a rounding, not memory casing effect, resulting in
invalid outcome
 2018-12-24 18:49:50 +00:00
Arjan van de Ven d321448a63 dgemm: use dgemm_ncopy_8_skylakex.c also for Haswell 
The dgemm_ncopy_8_skylakex.c code is not avx512 specific and gives
a nice performance boost for medium sized matrices
 2018-12-16 23:09:22 +00:00
Arjan van de Ven c43331ad0a dgemm: Use the skylakex beta function also for haswell 
it's more efficient for certain tall/skinny matrices
