A new command named nodeinfo is now available on the login nodes. It is a convenience script based on Slurm’s sinfo command and is intended to provide an overview of partitions, nodes, and their current state.
$ nodeinfo -h
nodeinfo / Display node information by partition, CPU/GPU model, and state
Options:
-p Filter partitions
* Default value shows all partitions
* Multiple partitions can be specified with comma separation
-s Filter node states
* Default value shows all nodes (in any state)
* Common node state options include the following:
alloc,down,drain,fail,idle,maint,mix
* Multiple options can be specified with comma separation
Examples:
nodeinfo
nodeinfo -h
nodeinfo -p epyc-64
nodeinfo -s idle
nodeinfo -s idle,mix
nodeinfo -p largemem -s idle
nodeinfo -p main,gpu -s idle,mix
Example for Discovery:
$ nodeinfo
