OSCAR Open Source Cluster Application Resources. The OSCAR is a snapshot of the best known methods for building, programming, and using clusters. It will hopefully bring some form of uniformity to clusters, foster commercial versions of the cluster software, and make clusters more broadly acceptable.
HA-OSCAR High Availability Open Source Cluster Application Resources is an open source project aims to provide a combined power of High Availability and Performance Computing solution. Our goal is to enhance a Beowulf cluster system for mission critical grade applications. To achieve high availability, component redundancy is adopted in HA OSCAR cluster to eliminate this single point of failure. HA-OSCAR incorporates a self-healing mechanism; failure detection & recovery, automatic failover and fail-back. (HA-OSCAR builds on Linux-HA).
Scyld Computing. The original Beowulf team providing second generation Beowulf Clustering.
OpenMosix (scalable computing clusters, including process migration). Unfortunately, it's not HA :-(.
Amata high-availability for Beowulf clusters.
Grid Engine. The Grid Engine project provides distributed resource management software for wide ranging requirements from compute farms to grid computing.
