Details:
- Added single-threaded and multithreaded sup performance results to
docs/PerformanceSmall.md for both sgemm and dgemm. These results were
gathered on an Epyc 7742 "Rome" server featuring AMD's Zen2
microarchitecture. Special thanks to Jeff Diamond for facilitating
access to the system via the Oracle Cloud.
- Updates to octave scripts in test/sup/octave for use with Octave 5.2
and for use with subplot_tight().
- Minor updates to octave scripts in test/3/octave.
- Renamed files containing the previous Zen performance results for
consistency with the new results.
- Decreased line thickness slightly in large/conventional Zen2 graphs.
I'm done tweaking those this time. Really.
- Added missing line regarding eigen header installation for each
microarchitecture section.
Details:
- Reran all existing single-threaded performance experiments comparing
BLIS sup to other implementations (including the conventional code
path within BLIS), using the latest versions (where appropriate).
- Added multithreaded results for the three existing hardware types
showcased in docs/PerformanceSmall.md: Kaby Lake, Haswell, and Epyc
(Zen1).
- Various minor updates to the text in docs/PerformanceSmall.md.
- Updates to the octave scripts in test/sup/octave, test/supmt/octave.
Details:
- Added section titled "Reproduction" to both Performance.md and
PerformanceSmall.md that briefly nudges the motivated reader in the
right direction if he/she wishes to run the same performance
benchmarks used to produce the graphs shown in those documents.
Thanks to Dave Love for making this suggestion.
Details:
- Corrected links in contents section of docs/PerformanceSmall.md,
which were erroneously directing readers to the corresponding
sections of docs/Performance.md.
Details:
- Spell out the hack given to me by Sameer Agarwal in order to get Eigen
to build with -march=native (which is critically important for Eigen)
in docs/Performance.md and docs/PerformanceSmall.md.
Details:
- Added the page size, as returned via 'getconf -a | grep PAGE_SIZE',
and the location of the performance drivers to docs/Performance.md
(test/3) and docs/PerformanceSmall.md (test/sup). Thanks to Dave
Love for suggesting these additions in #325.
Details:
- Updated the BLASFEO performance graphs shown in PerformanceSmall.md
using a new commit of BLASFEO (2c9f312); updated PerformanceSmall.md
accordingly.
- Updated test/sup/octave/plot_l3sup_perf.m so that the .m files
containing the mpnpkp results do not need to be preprocessed in order
to plot half the problem size range (ie: up to 400 instead of the
800 range of the other shape cases).
- Trivial updates to runme.m.
Details:
- Updated the graphs linked in PerformanceSmall.md with BLASFEO results,
and added documenting language accordingly.
- Updated scripts in test/sup/octave to plot BLASFEO data.
- Minor tweak to language re: how OpenBLAS was configured for
docs/Performance.md.
Details:
- Added a new markdown document, docs/PerformanceSmall.md, which
publishes new performance graphs for Kaby Lake and Epyc showcasing
the new BLIS sup (small/skinny/unpacked) framework logic and kernels.
For now, only single-threaded dgemm performance is shown.
- Reorganized graphs in docs/graphs into docs/graphs/large, with new
graphs being placed in docs/graphs/sup.
- Updates to scripts in test/sup/octave, mostly to allow decent output
in both GNU octave and Matlab.
- Updated README.md to mention and refer to the new PerformanceSmall.md
document.
