Maui Cluster Scheduler
Overview:
Maui is an advanced job scheduler for use on clusters and supercomputers. It is a highly optimized and configurable tool capable of supporting a large array of scheduling policies, dynamic priorities, extensive reservations, and fairshare. It is currently in use at hundreds of leading government, academic, and commercial sites throughout the world. It improves the manageability and efficiency of machines ranging from clusters of a few processors to multi-teraflop supercomputers.
Maui is a community project* and may be downloaded, modified, and distributed. It has been made possible by the support of Cluster Resources, Inc 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 Supercomputing Center (OSC), University of Southern California (USC), SDSC, MHPCC, BYU, NCSA, and many others.
Features:
Maui extends the capabilities of base resource management systems by adding the following features:- Extensive job priority policies and configurations
- Multi-resource admin and job advance reservation support
- Metascheduling interface
- Extensive fairness policies
- Multi-attribute fairshare
- Configurable node allocation policies
- Multiple configurable backfill policies
- Detailed system diagnostic support
- Allocation manager support and interface
- Extensive resource utilization tracking and statistics
- Non-intrusive 'Test' modes
- Advanced built-in HPC simulator for analyzing workload, resource, and policy changes

Maui is currently supported on all known variants
of Linux, AIX, OSF/Tru-64, Solaris, HP-UX, IRIX, FreeBSD, and other UNIX
platforms.
The Maui scheduler is mature, fully documented,
and supported. It continues to be agressively developed and possesses
a very active and growing user community. Its legacy
of pushing the scheduling envelope continues as we promise to deliver the
best possible scheduler supporting systems software will allow.
