flux-sched version 0.3.0 - 2016-10-28

  • Add configurable scheduling optimizations for throughput-oriented workloads (#190, #191):

    • sched-params=queue-depth=<k>: limits the number of jobs to consider per scheduling loop
    • sched-params=delay-scheduling=true: delays scheduling to batch up individual scheduling events

flux-sched version 0.2.0 - 2016-08-13

New Features

  • Versatile scheduling: replace resource tree list searches with tree searches.

  • Runtime selection of backfill algorithm (#159). Examples of selecting various algorithms are (first remove any loaded sched plugin, e.g., flux module remove sched.fcfs):

  • Conservative : flux module load sched.backfill reserve-depth=-1
  • EASY : flux module load sched.backfill reserve-depth=1
  • Hybrid : flux module load sched.backfill reserve-depth=4
  • Pure : flux module load sched.backfill reserve-depth=0

Fixes

  • Update to latest flux-core logging apis

  • Fix segfaults in simulator during shutdown

  • Small leak fixes in simulator

Deprecations

  • Remove sim_sched code that ran under simulator. The simulator now interfaces directly with sched module.

flux-sched version 0.1.0 - 2016-05-16

  • Initial release for build testing only
