Someone is hogging the cluster with lots of long jobs. What can I do?

This is where Partitions come in handy. The short version: If your jobs run only for 4 hours or less, you can use the high_prio QoS, either by adding --qos=high_prio to your srun command or the submit script. Or if you use plus_slurm or plus_slurm_matlab, you are going to find a QoS parameter there.

If you use the high_prio QoS:

1. Your jobs get priority over all jobs in the normal (default) queue.
2. Your jobs can even preempt (i.e. stop) jobs in the normal queue.
3. But: You are limited to 50% of the cores.

How can I change my default shell?

As we use FreeIPA for our User Management, you cannot use chsh to change your default shell. Instead, you can use the ipa command:

ipa user-mod --shell=/bin/bash USERNAME
