It improves the manageability and efficiency of machines ranging from clusters of a few processors to multi-teraflops supercomputers.
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, PNNL, the Center for High Performance Computing at the University of Utah (CHPC), Ohio Supercomputer Center (OSC), University of Southern California (USC), SDSC, MHPCC, BYU, NCSA, and many others.
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.
