STINNER Victor added the comment: sched_getaffinity() does not fail if the set is smaller than the number of CPU. Try with an initial value of ncpus=1. So we cannot start the heuristic with ncpus=16, because it would only return 16 even if the computer has more cpus.
Instead of this heuristic, why not simply alway using ncpus = CPU_SETSIZE? I don't know if CPU_SETSIZE is part of the standard (POSIX?). You may also use a constant size (CPU_SETSIZE) of the set used by sched_setaffinity() to simplify the code. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12655> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
