Wait, what?
So how many THREADS would you like to see ?
It should determine the number of cores at runtime as well as the level
of SSE/AVX support: i686 starts with the PentiumPro, which didn't have
SSE. Fixing this at compile time is nice for local builds, but no good
for packages.
Hi Achim,
feel free to require the feature upstream.
https://github.com/xianyi/OpenBLAS/issues
Building with NUM_THREADS=n should provide in the mean time
the maximum available.
The variable OPENBLAS_NUM_THREADS=m should allow to less than the
maximum.
Regards,
Achim.
building rev -2 with NUM_THREADS=16
