No, that's not right, we have overlapping partitions where one is for non-GPU 
jobs (which get 32 of 36 cores per node) and another for GPU jobs (which gets 
all 36 cores - our submit filter enforces partition selection) and a job from 
one partition can start on a node which has jobs from the other partition (or 
both) on it.

A job can be submitted to many partitions (modulo local policy) but once it 
starts it is only in one partition, that might be what you are thinking of 
here.

All the best,
Chris
