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: http://www.schedmd.com/slurmdocs/cgroups.html [memcg performance] > Yick!
