I am working on my first ever SLURM cluster build for use as a resource manager in a JupyterHub Development environment. I have configured the cluster for SelectType of 'select/con_res' with DefMemPerCPU and MaxMemPerCPU of 16Gb. The idea is to essentially provide for jobs that run in a 1 CPU/16Gb chunks. This is a starting point for us.
What I am seeing is that when users submit jobs and ask for memory only - in this case, 16Gb, SLURM actually allocates 2 CPUs, not 1 that I would expect. Is my understanding of how this particular configuration works incorrect?
