I'm running Fedora 21 with a custom compiled kernel, 3.19.0-1.20150211.fc21.x86_64. I have a multi core system with 6 cores. All are recognized by the kernel. But, when I run a compile job with -j6, in order to allow all six cores to be used, it limits the total amount of usage to 100% of a *single* core. So, it might use all six cores, but the sum of the percentages on those six cores is always around 100% of one core. This is from htop output. On large compilations, like the kernel or firefox, even using 4 cores could drastically reduce compile time. I've looked at /etc/security/limits.conf, but it doesn't seem to have a setting for this. I've also looked at the /proc system to see if there is a kernel variable, though that seems unlikely, with no luck. Online searching found ways to limit the amount that a single job can get, but not how to set this for a user. There must be a configuration variable somewhere that is limiting the amount of total cpu a user can use. But I can't find it. Can anyone help? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
