You probably want the batch scheduler to do the suspend/resume as it
may be parking part of the job on nodes that have memory but running
processes of a different job while moving a job out of the way for a
big-mem app that wants to run on one of this jobs nodes.

Software Vendors tend to be very reluctant to do things for a single
