I would also add, if the decision comes to make 'real exclusive' cpusets, my previous example, as a use for non-exclusive cpusets:
we are running jobs that need to be 'mostly' isolated on some part of the system, and run in a specific location. We use cpusets for that. But we can't afford to dedicate a part of the system for administrative tasks (daemons, init..). These tasks should not be put inside one of the 'exclusive' cpusets, even temporary : they do not belong there. They should just be allowed to steal a few cpu cycles from time to time : non exclusive cpusets are the way to go. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
