Casey Sybrandy commented on MESOS-314:
--------------------------------------

Regarding the use of cpuset, would it be possible to have the executor automatically pick a CPU to use on a per executor basis?  We have a number of containers we run in mesos and we'd love to be able to pin each running container to a single CPU.  Which CPU doesn't matter and we will be running multiple instances of the same container on a single node, so explicitly setting a value won't work for us.

> 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.
