Getting Info About Hardware

sinfo

To view information about nodes on the cluster either refer to the cluster's page, or use sinfo. With it you can see the number of processors available, the amount of memory the node has, which partition(s) it is a member of, and its features (which can be reqested as constraints with --contraint when submitting a job)
