IIUC Loris is looking for a method to do that automatically.
Since there is a "used memory" metric, a corresponding "wasted memory"
(or "wasted CPU") one with corresponding weights in priority
calculations could be useful.

Hi Loris, You could add them to a naughty list (please use a better
term...) and apply a fixed commensurate priority penalty. That is
simple (and can apply to a range of unpreferred behaviour) and provides
a clear motivation to change. Could be done with QOS unless you already
use that in a conflicting way.

*Subject:* [slurm-users] Fairshare: Penalising unused memory rather than
used memory?
Hi,
We have an increasing number of users who are unable (or unwilling) to
estimate their memory requirements accurately. We include memory in our
calculation of fairshare usage and thus penalise everyone who requests
large amounts of memory, whether it is needed or not.
Therefore I would be interested in knowing whether one can take into
account the *requested but unused memory* when calculating usage. Is
this possible?
Cheers,
Loris
