[slurm-users] [External] What is an easy way to prevent users run programs on the master/login node.

[Prentice Bisbal]

I think someone asked this same exact question a few weeks ago. The best 
solution I know of is to use Arbiter, which was created exactly for this 
situation. It uses cgroups to limit resource usage, but it adjusts those 
limits based on login node utilization and each users behavior ("bad" 
users get their resources limited more severely when they do "bad" things.

I will be deploying it myself very soon.
