Thanks, I'll look into that.

That's probably not even necessary -- the problem at hand is that with OMP_NUM_THREADS unset, (some) jobs will grab an entire node even if assigned just a few CPUs. However, our PEs are set up with allocation_rules of $pe_slots or n (where n is the number of cores on the node), so multi-node jobs never have to share any of their nodes.
