Each host will run a single pbs_mom daemon that will report itself as
multiple virtual nodes, one per NUMA node. At one point, I had a test
system configured with three hosts, each of which had 4 NUMA nodes; when
you ran pbsnodes -a on it, it looked like 12 nodes. The scheduler has
to know how to glue these virtual nodes back together, which IIRC Moab
does with its nodeset functionality.
