| Date: | Mon, 10 Oct 2022 06:17:00 -0400 (EDT) |
Follow-up Comment #18, bug #63184 (project octave):
It gets better (though still slower than openblas)
if I use both libflame and libblis:
$ BLIS_NUM_THREADS=16
LD_PRELOAD=/opt/AMD/aocl/aocl-linux-gcc-3.2.0/lib_LP64/libflame.so:/opt/AMD/aocl/aocl-linux-gcc-3.2.0/lib_LP64/libblis-mt.so
octave -q
octave:1> t_chol
octave:2> cumulate
cumulate = 1.8110
octave:3>
[dima@ryzen clang_opt]$ BLIS_NUM_THREADS=8
LD_PRELOAD=/opt/AMD/aocl/aocl-linux-gcc-3.2.0/lib_LP64/libflame.so:/opt/AMD/aocl/aocl-linux-gcc-3.2.0/lib_LP64/libblis-mt.so
octave -q
octave:1> t_chol
octave:2> cumulate
cumulate = 2.0418
Dmitri.
