Chaps, play nice please.
I am sure Mark Hahn is well aware of what batch schedulers can do.

Me, I come place myself in the camp of one job / one node (or one job / lots of nodes)
Jobs may run wild and trigger the OOM killer (say) (and YES I KNOW that you can put limits on memory usage in the batch scheduler).

I will also say that workloads vary - you may have long running jobs which do not require a lot of memory, and which could exist happily
with other jobs. YMMV. But in my experience dedicated nodes per job is preferable.
