[slurm-users] Simple free for all cluster

[John H]

Hi All

Hope you are all keeping well in these difficult times.

I have setup a small Slurm cluster of 8 compute nodes (4 x 1-core CPUs, 16GB RAM) without scheduling or accounting as it isn't really needed.

I'm just looking for confirmation it's configured correctly to allow the controller to 'see' all resource and allocate incoming jobs to the most readily available node in the cluster. I can see 
jobs are being delivered to different nodes but want to ensure I haven't inadvertently done anything to render it sub optimal (even in such a simple use case!)

Thanks very much for any assistance, here is my cfg:
