Here is a short summary with basic details.<br \/>\nIn short:<br \/>\n&#8211; Job waiting times will be more predictable and intuitive.<br \/>\n&#8211; Longer waiting times will increase the priority of a pending jobs.<br \/>\n&#8211; Jobs will still be able to access resources quickly if recent resource usage quotas are low.<br \/>\nDetails:<br \/>\n&#8211; A pending job will not be delayed by any other new jobs (see its expected start time increase into the future) after 24 hours of waiting.<br \/>\n&#8211; Note that other software or hardware malfunctions might still cause delays in jobs, but new jobs will no longer cause this after 24 hours.<br \/>\n&#8211; A pending job with low fair-share factor might still be delayed by new jobs with higher fair-share factors during the first 24 hours of waiting.<br \/>\n&#8211; The project used for a job (default or otherwise) will determine its fair-share priority factor based on recent resource usage.<br \/>\n&#8211; Projects that have already used their &#8222;fair-share&#8220; of resources, will have a lower fair-share priority factor than projects with lower recent resource usage.<br \/>\n&#8211; Priorities and fair-share priority factors only matter for comparing jobs waiting for the same resources (e.g: partitions).<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We updated Slurm to a newer and more stable Version: 25.05.5 This upgrade fixed issues we had with our scheduling system and internal rights-management database.
