Hello Slurm Folks, In a mailing list thread earlier this year ( https://groups.google.com/d/topic/slurm-devel/zaH9aXhBXLA/discussion ), Moe Jette mentioned that at the time, nodes assigned to multiple partitions could have their resources overcommitted if the Shared=Exclusive parameter was not set on all partitions including the nodes.
Is this limitation still present in Slurm? If not, in which version was it addressed? We would very strongly like to have nodes in multiple partitions in such a way that the consumable resource on each node could be either sockets or cores, without needing to worry about overcommitment. There is a table in the documentation on http://www.schedmd.com/slurmdocs/cons_res_share.html which implies that if Shared=No , we should see the behavior desired, but the bottom of that documentation page indicates a last modified date in 2008, which is older than the thread I linked above with Moe's comments, so I'm still pretty uncertain. Thank you. -- http://www.fastmail.fm - mmm... Fastmail...
