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.
> Support the cgroups 'cpusets' subsystem.

> 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.
