The machine that runs the CLI isn't usually a cluster node or run slurmd.<br>
<br>
The control node has to accept the user is who they claim and AFAIK that is<br>
the job of munge. And your onboard and external firewalls must allow the<br>
requisite ports.<br>
<br>
We used Galaxy (see <a href="http://galaxy.eu" rel="noreferrer" target="_blank">galaxy.eu</a> if unfamiliar) and could submit jobs to<br>
various job runners including Slurm. The galaxy node definitely didn't run<br>
any slurm daemons.<br>
<br>
I think you do need a common authentication system between the submitting<br>
node and the cluster, but that may just be what I'm used to.<br>
