Hi, We are trying to work out a method so that nodes will be used in the order we’d like. To try and illustrate this we have 3 groups lets call them: group1, group2 and group3. group1 is made up of some nodes and also includes group3. group2 is made up of a different set of nodes. When jobs are submitted they should be placed on group1 nodes or group2 nodes roughly equally balancing between the two, i.e. if there are 4 jobs using 4 nodes. They should take 8 nodes from group1 and 8 nodes from group2. group1 nodes should use all nodes that are NOT in group3 first, leaving group3 to be the last nodes selected. Their should also be a method of selecting group3 either by specifying resource or a queue. We have created resources for group1 and group2, and would submit with -l place=vscatter:excl:group=group What we are struggling with is the group3 nodes only to be used last in group1. Any ideas, would be most appreciated. Thanks ---

You can assign different priorities to nodes, like ```auto set node priority = ``` Within each group, set equal priorities. Nodes belonging to groups with higher priority will get jobs first.
