Z.22.1 About NUMA-Supported Systems
When Torque is enabled to run with NUMA support, there is only a single instance of pbs_mom (MOM) that is run on the system. However, Torque will report that there are multiple nodes running in the cluster. While pbs_mom and pbs_server both know there is only one instance of pbs_mom, they manage the cluster as if there were multiple separate MOM nodes.
The mom.layout file is a virtual mapping between the system hardware configuration and how the administrator wants Torque to view the system. Each line in mom.layout equates to a node in the cluster and is referred to as a NUMA node.
Z.22.2 Torque Installation and Configuration
To enable Torque for NUMA-support, you will need to add the --enable-numa-support option during the configure portion of the installation. You will also need create the mom.layout file and configure the server_priv/nodes file.

Z.22.3 Moab/Torque NUMA Configuration
Moab requires additional configuration to enable NUMA-support.
