Yeah, that's very much like what we do for GPU jobs (redirect them to the partition with access to all cores, and ensure non-GPU jobs go to the partition with fewer cores) via the submit filter at present.. I've already coded up something similar in Lua for our submit filter (that only affects my jobs for testing purposes) but I still need to handle memory correctly, in other words only pack jobs when the per-task memory request * tasks per node < node RAM (for now we'll let jobs where that's not the case go through to the keeper for Slurm to handle as now). However, I do think Scott's approach is potentially very useful, by directing jobs < full node to one end of a list of nodes and jobs that want full nodes to the other end of the list (especially if you use the partition idea to ensure that not all nodes are accessible to small jobs). cheers!
