[Octave-bug-tracker] [bug #61208] [MXE Octave] Launchers should set OPENBLAS_NUM_THREADS

[Dmitri A. Sergatskov]

Follow-up Comment #14, bug #61208 (project octave):

I think ideally we should let user to setup desired number of threads. On
16-core (32-threads) linux I set it to 8. I noticed that performance does not
increase much after that. I think running too many threads increases CPU T too
much so it reduces its frequency. So may be it is easier if the setting is
done in some kind of  a startup script rather than in an exe .

BTW, 10-25 fails test eigs (error in dneupd) -- not sure if 
this is related to too many openblas threads. 

Dmitri.
