Update of bug #55643 (project octave): Severity: 2 - Minor => 3 - Normal Priority: 3 - Low => 5 - Normal Status: Works For Me => Confirmed Release: 4.2.2 => 5.0.91 Summary: Missing some of my processor cores (nproc) => Function "nproc" just reports the environment variable OMP_NUM_THREADS not the "current number of available processors". _______________________________________________________ Follow-up Comment #8: You are right, also my Octave 5.0.90 installation can be fooled by the environment variable OMP_NUM_THREADS (see bug #51643). And I can even turn my laptop into a supercomputer :D OMP_NUM_THREADS=3000000 octave --eval 'system ("nproc"); system ("nproc --all"); nproc' 3000000 4 ans = 4 _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?55643> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
