    [ https://issues.apache.org/jira/browse/MESOS-314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14034682#comment-14034682 ] 

Timothy St. Clair commented on MESOS-314:
-----------------------------------------

FWIW - http://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface/

"For example cpuset or freezer are currently not exposed at all due to the broken inheritance semantics of the kernel logic. Also, migrating units to a different slice at runtime is not supported (i.e. altering the Slice= property for running units) as the kernel currently lacks atomic cgroup subtree moves."

> We'd like to add support for the cpusets subsystem, in order to support pinning to cpus.
> This has several potential benefits:
> 1. Improved isolation against other tenants, when given exclusive access to cores.
> 2. Improved performance, if pinned to several cores with good locality in the CPU topology.
> 3. An alternative / complement to CFS for applying an upper limit on CPU usage.
