SLURM uses a best-fit algorhthm. If you have topology/tree configured, the best-fit applies on a per-switch basis. Otherwise it applies to the 1-D list of nodes. In your case, you want 1 node and the choice is between a block of 84 nodes (1-84) or 15 nodes (86-100), so it picked from the block of 15 nodes. ________________________________________ From: [email protected] [[email protected]] On Behalf Of Michael Di Domenico [[email protected]] Sent: Friday, February 18, 2011 12:35 PM To: slurm-dev Subject: [slurm-dev] node allocation choice
How does slurm determine which node to use from a given node pool? To give a more specific example, if you had nodes 1 through 100, but node 85 was "down*". What causes slurm to grab node86 next instead of node1?
