5.603 Torque Multi-MOM

Starting in Torque version 3.0 users can run multiple MOMs on a single node. The initial reason to develop a multiple MOM capability was for testing purposes. A small cluster can be made to look larger since each MOM instance is treated as a separate node.

When running multiple MOMs on a node each MOM must have its own service and manager ports assigned. The default ports used by the MOM are 15002 and 15003. With the multi-mom alternate ports can be used without the need to change the default ports for pbs_server even when running a single instance of the MOM.
