The Maui Scheduler is a advanced job scheduler for
cluster systems.
It allows site administrators extensive control over which
jobs are considered eligible for for scheduling, how the
jobs are prioritized, and where these jobs are run. Maui
supports advance reservations, QOS levels, backfill, and
allocation management.
Its scheduling scheme is based on advanced wall-time
reservations with backfill. The main difference from other
common batch queue schedulers (e.g. NQS, DQS) is that Maui
allows jobs to overtake a job with higher priority if
and only if it does not delay the start of the
prioritized job (i.e. backfill).
