Lists information about Slurm nodes and partitions. Command output has 6 columns.

Partition: Slurm partitions
Avail: Partition availability
Timelimit: Partition max time limit
Nodes: Nodes in requested partition
State: State of nodes(mix, idle, down, draining, drained, mix, alloc)

  • idle:free,
  • down: node is down,
  • draining: issue about node and node is closed for new jobs. Node will be taken out of cluster after jobs are finished,
  • drained:node is closed to all jobs,
  • mix:some of resource on node is used,
  • alloc:resource on node is fully allocated(used). No resource available on node.

Nodelist: Nodes in partition
sinfo shows all partitions and nodes in cluster. For ai partition, you can use “sinfo|grep ai

[root@login02 ~]# sinfo|grep ai

In command output,

Partition: ai
Availibility: partition is upup
Time limit: max 7days
Nodes-State-Nodelist:
-There are 14 nodes with mix state. It means that some of resources on these nodes(ai[01,03-14],dy03) are used. There is still resource.
-There is only one node(dy02) fully allocated.
-There is only one node(ai02) free. fully available

⚠️⚠️⚠️ sinfo command is useful for listing resources in a short version. However, there is another command(kuacc-info) which is more detailed and more useful.
