I'm getting confused here, haven't had a coffee since Monday, must be the reason. :-) What we really want is for the usual execution of: mpiexec /path/to/my/code $arguments to launch via the PBS TM API, work out what cores are available to it on the nodes assigned to it and then bind appropriately to them.
