Instead each user of the system can see who is requesting excessive memory, using inappropriate queues or just inefficient workloads at scale. This creates a self-Policing environment and certainly both re-enforces a community feel and improves communication between the groups of users.<br>

Of course, if you charge for your cluster time, that hurts them in the wallet, since they pay for all the allocated unused time. If you don’t charge (which is the case for us) it’s hard to incentivise them not to do this. Shame works, a bit. We publish cluster analytics showing CPU efficiency and memory efficiency league tables for the users, and that has had some good effects in the past...<br>
