openMosix

openMosix was a free cluster management system that provided single-system image (SSI) capabilities, e.g. automatic work distribution among nodes.

[1] It was released as a Linux kernel patch, but was also available on specialized Live CDs.

On July 15, 2007, Bar announced that the openMOSIX project would reach its end of life on March 1, 2008, due to the decreasing need for single system image (SSI) clustering as low-cost multi-core processors increase in availability.

Traditionally, clustered computing could only be achieved by setting up individual rsh keys, creating NFS shares, editing host files, setting static IPs, and applying kernel patches manually.

The distribution contains an autoconfiguration system where new ClusterKnoppix-running computers attached to the network automatically join the cluster.
