Back in 2006 Srivatsa Vaddagiri summarised proposals for CPU controllers, which variously offered to limit or guarantee CPU for a task group. Some of these supported both soft and hard limits.
Now in 2008 we have FAIR_CGROUP_SCHED in mainline, which supports soft CPU limits per control group. Great stuff. Unfortunately I am keenly looking for a hard CPU limit implementation - i.e. one that would constrain a control group to use no more than x% of the CPU, even when it is otherwise idle. Has the hard limit idea been discarded, or is it still a planned feature (of either the Fair scheduler or a new subsystem)? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
