[slurm-users] Software and Config for Job submission host only

[Richard Chang]

Hi,

I am new to SLURM and I am still trying to understand stuff. There is
ample documentation available that teaches you how to set it up quickly.

Pardon me if this was asked before,  I was not able to find anything
pointing to this.

I am trying to figure out if there is something like PBS-execution only
for SLURM. Such that I can install it is the Login nodes and those nodes
will only be responsible for the job-submission and not job execution.

Is there any particular package to install and is there a different
config that needs to be put in the job submission only nodes ?

Basically, I want the job submission nodes to have all the commands and
all the things that will enable them to get reports,logs whatever an
admin and a user will need. Just not execution of the jobs.

Thanks in advance for your help.

RC.

Hello,

All you need to setup is the path to the Slurm binaries whether they are available via shared file system or locally on the submit nodes (srun, sbatch, sinfo, sacct, etc.) and possibly man pages.
Probably want to do this somewhere in /etc/profile.d or equivalent.

Hi Richard,

I was about to say, they need to have access to the configuration
(slurm.conf) and the binaries. And not run slurmd; starting slurmd is
what makes an execution host :)

There is nothing you need to do to allow job submission from them.

I build rpms; on the login nodes I install the 'slurm-xxxxxx' rpm but
not sslurmd-xxxxx (apart from 'contrib' for seff, and copy the
/etc/slurm/ directory.

Hope that helps!

Tina

Don’t forget about munge. You need to have munged running with the same key as the rest of the cluster in order to authenticate.
