Hello Nick, What is the result with only -n 1 ? Could you provide your slurm.conf ?
A lot of parameters are involved in the allocation process. The choice between a few cores or a whole node depends mostly of "SelectType" and "Shared" in the partition definition.

Why is that? Any suggestions would be greatly appreciated, Nick
