No, Slurm has to launch the batch script on compute node cores ... SNIP... Even with srun directly from a login node there's still processes that have to run on the compute node and those need at least a core (and some may need more, depending on the application).
Alright, understood.

I have 3500+ GPU cores available. You mean each GPU job requires at least one CPU? Can't we run a job with just GPU without any CPUs?
No, Slurm has to launch the batch script on compute node cores and it then has the job of launching the users application that will run something on the node that will access the GPU(s).
