Controlling number of threads in PLASMA

Postby jgpallero » Sat Dec 21, 2013 8:28 am

Hello:

As for multithreaded BLAS exists some environment variables like OMP_NUM_THREADS, GOTO_NUM_THREADS, OPENBLAS_NUM_THREADS, et al, which must be set as 1 in order to obtain good performance using PLASMA, exist any variable related to the number of threads used by PLASMA itself (like PLASMA_NUM_THREADS, for example), or uses PLASMA always the maximum available number of threads?

Thanks!

Well, I've found in the source code the answer: the PLASMA_NUM_THREADS environment variable yet exists. However, I suggest to add some reference to it in the User's guide :)
