[OMPI users] control openmpi or force to use pbs?

[Duke Nguyen]

Hi all,

Please advise me how to force our users to use pbs instead of "mpirun
--hostfile"? Or how do I control mpirun so that any user using "mpirun
--hostfile" will not overload the cluster? We have OpenMPI installed
with Torque/Maui and we can control users's limits (total number of
procs, total nodes, total memories etc) with Torque/Maui, but if a user
knows the cluster, and creates himself a hostfile with all the available
nodes then he can use them all.

Thanks,

D.
