Partitions

How are partitions managed on DAIC?

  less than a minute  

In SLURM, a partition is a scheduling construct that groups nodes or resources based on certain characteristics or policies. Partitions are used to organize and manage resources within a cluster, and they allow system administrators to control how jobs are allocated and executed on different nodes.

See partition definitions

On DAIC the scontrol command only shows you the general partitions. More partitions are available.
