That is actually how they recommended setting up GPU nodes in the Slurm docs a couple of years ago (maybe changed now). Make a ‘gpu’ partition with the nodes and another partition that contains the same nodes. The second partition can even limit the total number of CPUs per node to save at least one CPU per GPU for use in the GPU partition. We have put the GPU nodes into an ‘interactive’ partition because the ‘standard’ partition is heterogenous so we did not want to limit the CPUs available on any one node arbitrarily. Carl
