The caveat here is that if you share the submit node with others, then
you'll constrain their jobs too (perhaps undesirably).

DAGMan will also do the trick. A third option is to use concurrency limits.
Depending on why you only want to use 50 of 80 slots, another approach
would be to allow the job to use all slots when the pool is idle, but
have preemption (or suspend, depending on job characteristics) policy
that allows other users to come in.
