 There is a techie page at this location **[[cluster:207|Slurm Techie Page]]** for those of you who are interested in the setup.
-__This page is intended for users__ to get started with the Slurm scheduler. ''greentail52'' will be the slurm scheduler test "controller" and with several cpu+gpu compute nodes configured. Any jobs submitted should be simple, quick running jobs, like a "sleep" or "hello world" jobs. These compute nodes are still managed by Openlava.

 Same on the cpu only compute nodes. Features could be created for memory footprints (for example "hasMem64", "hasMem128", hasMem192", "hasMem256", "hasMem32"). Then all the cpu only nodes can go into one queue and we can stick all cpu+gpu nodes in another queue. Or all of them in a single queue. We'll see, just testing.
-On the resource requests: You may request 1 or more nodes, 1 or more sockets per node, 1 or more cores (physical) per socket or 1 or more threads (logical + physical) per core. Such a request can be fine grained or not; just request a node with ''--exclusive'' (test queue only) or share nodes (other queues, wit ''--oversubscribe'')

 //Note: this oversubscribing is not working yet. I can only get 4 simultaneous jobs running. Maybe there is a conflict with Openlava jobs. Should isolate a node and do further testing. After isolation (n37), 4 jobs with -n 4 exhausts number of physical cores. Is that why 5th job goes pending?//
