Hi,
Our cluster has a handful of login nodes, and then a bunch of
compute nodes. OpenMPI is installed in a global file system
visible from both sets of nodes. This means users can type
"mpirun" from an interactive prompt, and quickly oversubscribe
the login node.
So, is there a way to explicitly exclude hosts from consideration
for mpirun? To prevent (what is usually accidental) running
MPI apps on our login nodes? Thanks!
