Does Maui honor resource manager classes/queues?
Why does PBS occasionally hang when Maui queries it? Its not my fault! Really! There are a number of problems with the PBS MOM query interface. These can be remedied by taking the following steps: – apply the PBS patches provided by Sandia National Laboratory (see the ‘PBS Integration Guide’) – build PBS without using RPP (use ‘configure’ option ‘–disable-rpp’) Scheduling Behavior What is the best way to backfill? Surprisingly, numerous studies and simulations have shown that there is not much difference in how you backfill (Much to my disappointment, it was my Master’s thesis 🙁 ) A continuously optimizing backfill scheduler will backfill jobs as fast as they are submitted leaving the scheduler with few decisions to make each iteration because its job/resource selection was minimized on the previous scheduling iteration. However, Maui supports a number of scheduling algorithms and criteria which you can play with. See the parameters documentation on BACKFILLPOLICY and BACKFILLMETRIC
