Subject: Re: [OMPI users] Mixing Linux's CPU-shielding with mpirun's bind-to-core

On a bug system you can boot the system into a 'boot cpuset'.
So all system processes run in a small number of low numbered cores. Plus
any login sessions. The batch system then crwtes cpusets in the higher
numbeted cores - free from OS interference.
