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
