Cluster Status
The general status of nodes/partitions in a cluster can be viewed using the sinfo and scontrol commands.
sinfo
sinfo will show you the status of partitions in the cluster. Passing the -N flag will show each node individually.
tgray26@opensub00:sinfo PARTITION AVAIL TIMELIMIT NODES STATE NODELIST dpart* up infinite 8 idle openlab[00-07] gpu up infinite 2 idle openlab[08-09]
tgray26@opensub00:sinfo -N NODELIST NODES PARTITION STATE openlab00 1 dpart* idle openlab01 1 dpart* idle openlab02 1 dpart* idle openlab03 1 dpart* idle openlab04 1 dpart* idle openlab05 1 dpart* idle openlab06 1 dpart* idle openlab07 1 dpart* idle openlab08 1 gpu idle openlab09 1 gpu idle
scontrol
The scontrol command, while generally reserved for administrator use, can be used to view the status/configuration of the nodes in the cluster. If passed specific node name(s) only information about those node(s) will be displayed, otherwise all nodes will be listed. To specify multiple nodes, separate each node name by a comma (no spaces).
