I was thinking of a similar issue. My plan was to have a single dynamic slot
for the server (assigned all the CPUs and all the RAM), to try to ensure no
over-subscription. Is this a reasonable approach? Are there reasons not to
do it this way?
Obviously the job might use more resources than it declares, but I'm not so
worried about this. I trust the users submitting the jobs, and if I didn't I
could probably ulimit them.
