Details:
- Updated the level-3 performance graphs in docs/graphs with new Eigen
results, this time using a development version cloned from their git
mirror on March 27, 2019 (version 3.3.90). Performance is improved
over 3.3.7, though still noticeably short of BLIS/MKL in most cases.
- Very minor updates to docs/Performance.md and matlab scripts in
test/3/matlab.
Details:
- Updated the Haswell, SkylakeX, and Epyc performance graphs in
docs/graphs to report on Eigen implementations, where applicable.
Specifically, Eigen implements all level-3 operations sequentially,
however, of those operations it only provides multithreaded gemm.
Thus, mt results for symm/hemm, syrk/herk, trmm, and trsm are
omitted. Thanks to Sameer Agarwal for his help configuring and
using Eigen.
- Updated docs/Performance.md to note the new implementation tested.
- CREDITS file update.
Details:
- Added targets to test/3/Makefile that link against a BLAS library
build by Eigen. It appears, however, that Eigen's BLAS library does
not support multithreading. (It may be that multithreading is only
available when using the native C++ APIs.)
- Updated runme.sh with a few Eigen-related tweaks.
- Minor tweaks to docs/Performance.md.
Details:
- Added a new markdown document, docs/Performance.md, which reports
performance of a representative set of level-3 operations across a
variety of hardware architectures, comparing BLIS to OpenBLAS and a
vendor library (MKL on Intel/AMD, ARMPL on ARM). Performance graphs,
in pdf and png formats, reside in docs/graphs.
- Updated README.md to link to new Performance.md document.
- Minor updates to CREDITS, docs/Multithreading.md.
- Minor updates to matlab scripts in test/3/matlab.
