We have two clusters running moab and slurm. Still using Moab 5.4 though. > I believe I've correctly followed the various integration guides for > these applications.

I submit a job requesting a > single node: What SelectType do you have configured in slurm.conf? One possible cause would be if you are using select/linear, in that case what you see would be the expected behavior. To allocate only part of a nodes resources to a job you need to use select/cons_res. (Note that changing SelectType will purge all jobs from the system when you restart) Kind regards, Pär Andersson NSC
