New submission from Satrajit Ghosh: multiprocessing cpucount returns the number of cpus on the system as returned by /proc/cpuinfo.
this is true even on machines where linux kernel cgroups is being used to restrict cpu usage for a given process. this results in significant thread swithcing on systems with many cores. some ideas have been implemented in the following repos to handle cgroups: https://github.com/peo3/cgroup-utils http://cpachecker.googlecode.com/svn-history/r12889/trunk/scripts/benchmark/runexecutor.py it would be nice if multiprocessing was a little more intelligent and queried process characteristics. ---------- components: Library (Lib) messages: 262881 nosy: Satrajit Ghosh priority: normal severity: normal status: open title: cgroups support in multiprocessing type: behavior _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26692> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
