Isn't this what bf_continue is for? bf_continue The backfill scheduler periodically releases locks in order to permit other operations to proceed rather than blocking all activity for what could be an extended period of time. Setting this option will cause the backfill scheduler to continue processing pending jobs from its original job list after releasing locks even if job or node state changes. This can result in lower priority jobs being backfill scheduled instead of newly arrived higher priority jobs, but will permit more queued jobs to be considered for backfill scheduling. It's part of what we use to cope with many thousands of jobs pending in our queues (defer is also really useful too). cheers, Chris -- Christopher Samuel Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: [email protected] Phone: +61 (0)3 903 55545 http://www.vlsci.org.au/ http://twitter.com/vlsci
