[slurm-users] Does the slurmctld node need access to Parallel File system and Runtime libraries of the SW in the Compute nodes.

A quick nuance:
We only have home directories on the login node. Our software 
installations are not accessible from there to prevent users from 
running things there (you must have a running job to access the software 

So your login node does not necessarily need everything the compute 
nodes do.
