I use cset shield (cpuset package) in a script to create a set and migrate everything that's permitted into the system set. setup: cset shield --userset=rtcpus --cpu=4-63 --kthread=on <poke this/that> teardown: cset shield --userset=rtcpus --reset <un-poke this/that> Non-sexy, but works for simple stuff. -Mike -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
