Check the Status of Compute Processors
How to use the xtprocadmin and xtnodestat commands.
Use the xtprocadmin command on a service node to check that compute nodes are available after the system is booted.

Identify nodes in down or admindown state
nid00007> xtprocadmin | grep down
Use the user xtnodestat command to display the current allocation and status of each compute processing element and the application that it is running. A simplified text display shows each processing element on the Cray system interconnection network.
