Kerrighed is a Single System Image operating
system (SSI) for clusters. It offers the view of a
unique SMP machine on top of a cluster of standard
PCs. The goals are high performance of
applications, high availability of the cluster,
efficient resource management, high
customizability of the operating system, and ease
of use. It is implemented as an extension to Linux
operating system (a set of Linux modules and a
small patch to the kernel).
