Thanks for the patch. This will be in v2.2.5. ________________________________________ From: [email protected] [[email protected]] On Behalf Of Bjørn-Helge Mevik [[email protected]] Sent: Tuesday, April 26, 2011 1:53 AM To: [email protected] Subject: [slurm-dev] Patch to filter out nodes with RAM < ncpus*mem-per-cpu
This is on slurm 2.2.4. We discovered that a few jobs that took very long time in the backfill were specifying --ntasks-per-node and --mem-per-cpu such that only a few nodes in our cluster had enough RAM. The job_req_node_filter function in src/slurmctld/node_scheduler.c didn't filter out the nodes with too little RAM for these jobs, so here is a suggested patch for it to do so. We've tested it on our test cluster and are now using it on the production cluster, and it seems to work well.
