How are the processes on the parallel jobs' nodes started? If it's done using 
rsh (which is also used in mpirun, for example), then Torque cannot know 
anything about the spawned processes and their resource usage. It only 
accounts for the children of the PBS script (i.e. the possible mpirun and rsh 
child processes), but not the processes on remote nodes.

Try Pete Wyckoff's mpiexec which supports spawning remote processes through 
Torque's TM interface.
