To slightly rephrase:
Torque is only managing and assigning resources (nodes and/or cpus and/or
You are responsible to get you application(s) running on the nodes you get.
Usually this is done via mpiexec or similar scripts running on the first
node of your assigned one spawning children on the other nodes.
