Thanks Brian! I'll take a look at weights. I want others to be able to use them and take advantage of the large memory when free. We have a preemptable partiton below that works great. PartitionName=scavenge AllowGroups=ALL AllowAccounts=ALL AllowQos=scavenge,abc AllocNodes=ALL Default=NO Q

Just to add the conversation. We also wrote our own GRES/plugin for this. Similarly the GRES enables the user to select the amount of GB units that they require. The plugin part invokes LVM to create a logical volume on an SSD device for the requested size. The volume is then made available to t
