Hello, there. I've found a pretty nasty bug with the pthreads version of the OpenBLAS package on the main repos. The TL;DR is that if you happen to link it in (in my case, it was brought in through OpenCV) it kills OpenMP for the entire thing, as if it had defined
omp_get_num_procs()andomp_get_max_threads()to always return 1.I've been trying to chase the bug down to suggest a fix and while doing it, noticed that the updated version (0.3.4) of the package in the science factory repo does not have the problem.
I'm looking for the right channel to bring this information to such that the bug can be worked out of the main upstream repositories. Would this be it?
I've been going in more detail in a thread on the forums ( https://forums.opensuse.org/showthread.php/534152-OpenBLAS-(-openblas_pthreads0-)-disables-OpenMP-for-whatever-it-s-linked-into )
If this is not it, could you point me in the right direction. I'm willing to bang my head against this a little more to help zero in a smooth fix
