Dear team,
Today I tried to use the AMD opensource version of blas by renaming and
copying the dll AOCL-LibBlis-Win-dll.dll (C:\Program
Files\AMD\AOCL-Windows\amd-blis\lib\LP64) to libblas.dll ( C:\Program
Files\GNU Octave\Octave-7.2.0\mingw64\bin) .
The libs can be downloaded from
https://developer.amd.com/amd-optimizing-cpu-libraries_eula/

I noticed a speedup from  1.51017 seconds (openblas) to 1.28942 seconds (AOCL)
on my AMD 5950x machine for the following code:

a2 = ones(2000,'single');
tic
for i = 1:100
a2*a2;
end
toc

In the meantime, as seen in the attached fig, I have a problem with lapack
while renaming and copying the dll AOCL-LibFlame-Win-MT-dll.dll （C:\Program
Files\AMD\AOCL-Windows\amd-libflame\lib\LP64）to liblapack.dll ( C:\Program
Files\GNU Octave\Octave-7.2.0\mingw64\bin) .

One reason I am doing this was that now matlab 2022 starts to support those
libs:
https://uk.mathworks.com/matlabcentral/answers/1672304-how-can-i-use-the-blas-and-lapack-implementations-included-in-amd-optimizing-cpu-libraries-aocl-wi
I guess if AOCL is open source, we can give the community more options to
choose the libs and speedup their programs.
