Depends on what you do, for some contorted reason we have 2 cpu control groups, cpusets and this other thing. I'm still wanting to fold them into one, this confusion is in part because of that train-wreck. You can place a task in one cpuset cgroup and in another scheduler cgroup - but yeah, that does interact funny with the load-balancer. > > > > __1__ > > / \ > > 2 3 > > (50% rt) (50% rt ) > > > > For my application domain;) it would be interesting to have > > rt_runtime_ns as a min. of allocated rt and not a max. > > Ex.

This doesn't sound a like a real-time application. Variable bandwidth is useless for determinism. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
