Thanks for the response. In the last 5 minutes I have managed to get some output from the prologue.parallel scripts, it turns out that the Torque Administrator's Manual was wrong, and I was fool enough to believe it! Now that I've got a working model I can start to sort out the mess with psm_shm files.
For your information: we were supplied with a script when we bought the cluster, but the original script made the assumption that all processes and shm files belonging to a specific user ought to be deleted. This is a problem if users submit jobs which only half fill a node and the second job starts on the same node as the first one. The first job to finish causes the continuing job to stop dead. We therefore had to disable any cleanup to allow jobs to run. Now we are finding a slow fill up with the shm files and I need to do something; at least now I have a way forward.
