How can I prevent users from running big jobs on the cluster headnode and force them to use only the slurm batch system?

Where am I?

By application of the cluestick.

Seriously though you can have a cgroup set up for login shells, so you can restrict how much resources a user will use. You could even use old fashioned ulimits to restrict resource usage.

I have never implemented that cgroup restriction for logins, but did look at it seriously once.
