When you log into Phoenix, you are placed on the login module. The login module should be used for basic tasks such as file editing, code compilation, data backup, and job submission.

The login module should not be used to run production jobs. Production work should be performed on the system’s compute resources. On Phoenix, access to compute resources are managed by PBS. Job scheduling is handled by Moab, which interacts with PBS and the X1E’s system software. This document provides information for getting started with the batch facilities of PBS with Moab as well as basic job execution on Phoenix and the cross-compiler Robin.
