Cluster Information

The Scontrol Command

To find more information about a partition like AllowGroups, AllowAccounts, MaxNodes, QoS, etc, the scontrol show command can be used to view the information.

Syntax : scontrol show partition <partition-name>

scontrol show partiton normal

Output :

PartitionName=normal
   AllowGroups=ALL AllowAccounts=ALL AllowQos=ALL
   AllocNodes=ALL Default=YES QoS=p-normal
   DefaultTime=00:01:00 DisableRootJobs=NO ExclusiveUser=NO GraceTime=0 Hidden=NO
   MaxNodes=UNLIMITED MaxTime=7-01:00:00 MinNodes=0 LLN=NO MaxCPUsPerNode=UNLIMITED
   Nodes=discovery-c[1-15]
   PriorityJobFactor=1 PriorityTier=25 RootOnly=NO ReqResv=NO OverSubscribe=FORCE:1
   OverTimeLimit=NONE PreemptMode=SUSPEND
   State=UP TotalCPUs=624 TotalNodes=15 SelectTypeParameters=NONE
   JobDefaults=(null)
   DefMemPerCPU=512 MaxMemPerNode=UNLIMITED

The above output shows detailed information about the normal partition. It also shows QoS information QoS= p-normal which is discussed in detail in the next section.
