I'm trying to set up slurm to run on my uni's server so we can take turns running experiments (so people running longer experiments don't block people with shorter experiments from running their stuff until they're done)
Since the server is a single node I'm trying to set up a simple GANG scheduling system where programs take turns running. However on startup I get the following info when calling systemctl status slurmctld:
× slurmctld.service - Slurm controller daemon
