Release Notes


This version of flux-sched integrates our new graph-based scheduler with the new execution system within flux-core. For this purpose, it introduces the qmanager module that can easily enforce various queuing and backfilling policies on batch jobs while serving as a conduit between our resource matching service and flux-core’s job-manager. In addition, it adds a new resource match policy that considers the performance class of each compute node as a constraint for scheduling to handle the natural performance variations of modern microprocessors. Finally, this version lays some of the foundational work to allow flux-sched to ultimately reconstruct its state using the queue state of job-manager for resiliency.
