Hey Graziano,

To make your decision more "data-driven", you can pipe your SLURM
accounting logs into a tool like XDMOD which will make you pie charts of
usage by  user, group, job, gres, etc.


You may also consider assigning this task to one of your "machine learning"
researchers and ask them to "predict" the resources needed. :)
