SLURM Partitions

Partitions are work queues that have a set of rules/policies and computational nodes included in it to run the jobs.

A list of partitions defined on the cluster, with access rights and resources definition, can be displayed with the command sinfo:

> sinfo -o "%10D %20F %P"

The command returns a more readable output which shows, for each partition, the total number of nodes and the number of nodes by state in the format "Allocated/Idle/Other/Total".

Partition Table

In the following table you can find the main features and limits imposed on the partitions.

Note: cpu refers to a logical cpu (1 HT).
