Node usage graph

There is a graphing tool that uses elements directly from sacct to display information about the current cluster usage, node_usage_graph (located at /cm/shared/apps/accounting/node_usage_graph ).

Example: <source lang="text"> [user@nfs01 ~]# /cm/shared/apps/accounting/node_reserved_usage_graph node: |0% 100%| fat001: DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD

This gives an overview of the current per-node resource usage. There are four types of letter:

• M: Memory reserved and in use
• m: Memory reserved and not in use
• C: CPU reserved and in use
• c: CPU reserved and not in use
• D: Drained node (not available for submission for some adminstrative reason
• R: Reserved node

It cannot however give you an indication of how much the queue is right now for any node. for that, squeue is a better resource.
