In every PBS environment I have used, you have to *both* tell PBS how many
nodes you want, and tell mpirun now many cpus you are using. On our openMPI
+ PBS system, you also have to tell mpirun about the hostfile that PBS
creates, so I write something like this:
mpirun -np 8 -hostfile $PBS_NODEFILE /path/to/sander.MPI flags go here
Every PBS installation might be set up in a different fashion, but something
like that listed above is likely to be required.
...good luck...dac
