Details:
- Added various micro-kernels for the following architectures:
Intel MIC
IBM BG/Q
IBM Power7
AMD Piledriver
Loogson 3A
and reorganized kernels directory. Thanks to Tyler Smith, Mike Kistler,
and Xianyi Zhang for contributing these kernels.
- Added configurations corresponding to above architectures, and renamed
"clarksville" configuration to "dunnington".
Details:
- Added two more arguments to the gemm and gemmtrsm microkernels: the
addresses of the next micro-panels of A and B. By passing these
pointers into the micro-kernel, we allow the micro-kernel author to
prefetch micro-panels of A and B as necessary (though this is
completely optional; these addresses may also be safely ignored).
- Updated all seven macro-kernels so that they compute and pass in
a_next and b_next. Note that ONLY the gemm macro-kernel computes
a_next and b_next with the precise semantics we want. I will go back
and fix the other macro-kernels in the near future.
- Added 'restrict' to various micro-kernels from which it was missing.
Details:
- Updated frame/util/dupl/bli_dupl_unb_var1.c to utilize PACKNR and NR
explicitly so navigate b1 so that situations where PACKNR > NR are
supported.
- Moved the 4x2 and 4x4 reference micro-kernels in frame/3/gemm/ukernels and
frame/3/trsm/ukernels to kernels/c99/.
- Updated clarksville and flame configurations.
