Hello, I think you are looking for the LLN option (Least Loaded Nodes): https://slurm.schedmd.com/slurm.conf.html#OPT_LLN

I've noticed that if no other jobs are running, and I submit a single job via srun, with no parameters to specify anything other than the defaults, the job *always* runs on the first node in slurm.conf. This seems like it would lead to some hosts getting overused and others getting underused. I'd like the stress on our hardware to be reasonably evenly distributed.
