Generally it is best that they should be. Slurm maps the users
environment into the job submission. So if things change in the OSt
under it it can lead to issues.

I'm attempting to set up a new submit host with a different OS (major)
version than the compute cluster. Should this be doable?
I have an OpenMPI app I can submit, using sbatch and qsub, from a
cluster node and it runs fine. However, when I submit from the new
host it fails. Initially I didn't have the compiler or OpenMPI even
installed on the new submit host which resulted in missing library
errors. So I installed them even though they'll never be used on the
new host. Now I'm fighting OpenMPI errors. It seems like incorrect
settings or information are being gathered from the new submit host
and then applied on the compute nodes. I don't care about the
environment of the new submit host at all though. I just want it to be
able to launch jobs with apps that have been built on the cluster.
Does a submit host have to be the same OS as a compute cluster?
