The SLURM Job Scheduler

Because the Keck Cluster is a shared resource, a job scheduler is used to provide fair access to all cluster users.

The scheduler used on the Keck Cluster is SLURM.
Users on the cluster submit requests for resources to the cluster scheduler
If the scheduler finds a block of resources large enough to satisfy the user’s request, it allocates those resources to the user immediately
If there aren’t enough resources free when the request is submitted, the user’s submission is placed in the queue specified in the user’s request
On the Keck Cluster, SLURM is configured to use a history-aware weighted-fair-queuing algorithm to decide which queued requests to run first
SLURM can be used to request interactive sessions or to submit batch jobs
