So very hetero, I did some testing and I couldn't make it happen below 32
cores. Not sure if this the real issue or if it requires a specific layout:
[brockp@nyx5512 ~]$ cat $PBS_NODEFILE | sort | uniq -c
1 nyx5512
1 nyx5515
1 nyx5518
1 nyx5523
1 nyx5527
2 nyx
Do you know the topology of the cores allocated by Torque (i.e. were
they all on the same nodes, or 8 per node, or a heterogenous
distribution for example ?)

Yes the request to torque was procs=64,
We are using cpusets.
the mpirun without -np 64 creates 64 spawned hostnames.

Hi,
Just an idea here. Do you use cpusets within Torque ? Did you request
enough cores to torque ?
