Chapter N Using NUMA with Moab

Moab works with Torque to support these two Non-Uniform Memory Architecture (NUMA) systems:

• NUMA-Aware – Introduced with Torque version 6.0, this configuration supports multi-req jobs and jobs that span hosts. Moab version 9.0 and later is also required.
• NUMA-Suppport – Introduced with Torque version 3.0, this configuration supports only a single instance for pbs_mom that as treated as if there where were multiple nodes running in the cluster. This configuration is only for large-scale SLES systems using SGI Altix and UV hardware.

This chapter serves as a central information repository for the various configuration settings involved when using either NUMA system configuration.
