Works only if you do not set
JOBNODEMATCHPOLICY EXACTNODE
But if that is not set then user B cannot submit his job.
That's the whole point: you cannot satisfy both users:
user A wants to run a job using 20 cpus anywhere on the cluster
AND
user B wants to run a job using 20 cpus with exactly one cpu on each
node.

Cheers,
Martin
