We do something like this in our cluster.  The idea we use is that you
have a routing queue "batch" that tries to place a job first in the
"standard" queue.  This succeeds only if the job requests less than 100
nodes, otherwise the job falls through to the "night_queue" queue.

Any comments from our more knowledgeable colleagues?
