You would need to disable Moab resource selection and let SLURM pick
resources to take advantage of the topology information. I'm not sure
what the Moab option is to do that, but I know that it's required for
BlueGene systems.
Quoting Jon Bringhurst <[email protected]>:
So, lets say we have a fat tree machine running slurm/moab with
mostly default settings. Would there be any performance impact if a
slurm topo file was created and the topology/tree plugin was enabled?
My guess is no (since moab wouldn't be aware), but I'm not really sure.
