System partitions

System partitions

To determine which partitions (queues) exist on a cluster you can use the sinfo -s command. Below is the command output from Cyclone.

sinfo -s
PARTITION AVAIL  TIMELIMIT   NODES(A/I/O/T) NODELIST
batch*       up   infinite        29/4/0/33 cn[01-17],gpu[01-16]
gpu          up 1-00:00:00        16/0/0/16 gpu[01-16]
cpu          up 1-00:00:00        13/4/0/17 cn[01-17]

The command shows the partition name, status, maximum time limit, node availability and node list.

  • cpu: compute nodes partition
  • gpu: GPU nodes partition
  • phi: phi nodes partition (Cyclamen only)
  • batch: all nodes partition. Can only be used by root.
