Details:
- Rewrote level-1v, -1f, and -3 reference kernels in terms of simplified
indexing annotated by the #pragma omp simd directive, which a compiler
can use to vectorize certain constant-bounded loops. (The new kernels
actually use _Pragma("omp simd") since the kernels are defined via
templatizing macros.) Modest speedup was observed in most cases using
gcc 5.4.0, which may improve with newer versions. Thanks to Devin
Matthews for suggesting this via issue #286 and #259.
- Updated default blocksizes defined in ref_kernels/bli_cntx_ref.c to
be 4x16, 4x8, 4x8, and 4x4 for single, double, scomplex and dcomplex,
respectively, with a default row preference for the gemm ukernel. Also
updated axpyf, dotxf, and dotxaxpyf fusing factors to 8, 6, and 4,
respectively, for all datatypes.
- Modified configure to verify that -fopenmp-simd is a valid compiler
option (via a new detect/omp_simd/omp_simd_detect.c file).
- Added a new header in which prefetch macros are defined according to
which compiler is detected (via macros such as __GNUC__). These
prefetch macros are not yet employed anywhere, though.
- Updated the year in copyrights of template license headers in
build/templates and removed AMD as a default copyright holder.
