Slurm Howto
Preface
This is a collection of howtos and convenient commands that I initially wrote for internal use at Ulm only. Scripts and commands have been tested within our Slurm test environment at JUSTUS (running Slurm 19.05 at the moment).
Maybe you find this collection useful, but use on your own risk. Things may behave differently with different Slurm versions and configurations.

JOB SUBMISSION
How to submit an interactive job?
Use srun command, e.g.:
$ srun --nodes=1 --ntasks-per-node=8 --pty bash
How to enable X11 forwarding for an interactive job?
Use --x11 flag, e.g.
$ srun --nodes=1 --ntasks-per-node=8 --pty --x11 bash # run shell with X11 forwarding enabled $ srun --nodes=1 --ntasks-per-node=8 --pty --x11 xterm # directly launch terminal window on node
Note:
- For X11 forwarding to work, you must also enable X11 forwarding for your ssh login from your local computer to the cluster, i.e.:
local> ssh -X <username>@justus2.uni-ulm.de>
