Both. The idea would be to apply gentle (or not so gentle, depending
on how important the job is ...) reclaim pressure to all the nodes
owned by a job. If you free up enough memory, you can then consider
migrating the allocated pages from one node into other nodes belonging
to the job, and hence reclaim a node for use by some other job.
