Wouldn't it be the other way around with the resource manager setting
limits and then having the job run inside it? Basically like the
current cpuset support in Torque, et. al, but on steroids.
That way mpirun and/or orted could learn from the kernel the details
of the cgroup it is in and arrange itself appropriately.
I believe that Slurm has some support for cgroups already:
