Maui Cluster Scheduler
Encyclopedia
Maui Cluster Scheduler is a job scheduler
for use on clusters and supercomputer
s initially developed by Cluster Resources, Inc.. Maui is capable of supporting multiple scheduling policies, dynamic priorities, reservations, and fairshare capabilities. Maui satisfies some definitions of open-source software
and is not available for commercial usage.
It improves the manageability and efficiency of machines ranging from clusters of a few processors to multi-teraflops supercomputers.

Maui Cluster Scheduler is currently maintained and supported by Adaptive Computing, Inc., although most new development has come to a standstill. A next-generation non-open-source scheduler is part of the Moab Cluster Suite
and borrows many of the same concepts found in Maui. Maui's developers state that the licence satisfies some definitions of open-source software
and that it is not available for commercial usage.
Adaptive Computing's Maui project is not associated with the Maui Scheduler Molokini Edition, which was developed as a project on the SourceForge
site independent of the original Maui scheduler, under the GNU Lesser General Public License
. The Molokini Edition's most recent release was in 2005.

Development and support
Maui was most heavily developed during the mid-90s. Development slowed into the 2000's, although an active community around the usage of Maui still exists. Its development was made possible by the support of Cluster Resources, Inc. (now Adaptive Computing) and the contributions of many individuals and sites including the U.S. Department of Energy, PNNLPacific Northwest National Laboratory
