Hi all: I have a user who is requesting that the scheduler system be modified such that jobs are not packed in by default. On our cluster, it is rarely running at or near 100%. This user would prefer that only one job is run per node unless all the nodes are full; at which point, it can start packing things in more closely.
I thought this is most aptly controlled by NODEALLOCATIONPOLICY, which I have set to MINRESOURCE. I do have some nodes that have IB, and some nodes that are 16-core nodes with twice the ram per core, but the majority of my nodes are just 8-core/8GB ram nodes, and those are fine for the majority of jobs/users. So I want to make sure by default, those are used unless they don't meet the specified resources, or they're already busy (and the other nodes aren't). So, Is NODEALLOCATIONPOLICY the setting I should be looking at? What exactly is MINRESOURCE's policy for job packing? --Jim _______________________________________________ mauiusers mailing list [email protected] http://www.supercluster.org/mailman/listinfo/mauiusers
