Hi Gareth-
The vmem and pvmem options doesn't seem to make any difference.
Incidentally, since the different nodes have different size memory compliments,
and I will be distributing multi-processor jobs across nodes, I absolutely need
something that will allocate on a per-processor memory basis. Here's a more
detailed rundown of what is available in the cluster:
$ diagnose -n
