OpenMosix is a Linux kernel extension for single-system image clustering. This kernel extension turns a network of ordinary computers into a supercomputer for Linux applications. Once you have installed openMosix, the nodes in the cluster start talking to one another and the cluster adapts itself to the workload. Processes originating from any one node, if that node is too busy compared to others, can migrate to any other node. With openMosix' Auto Discovery, a new node can be added while the cluster is running and the cluster will automatically begin to use the new resources. There is no need to program applications specifically for openMosix. Since all openMosix extensions are inside the kernel, every Linux application automatically and transparently benefits from the distributed computing concept of openMosix. OpenMosix is a simple way to set up a cluster.
The current implementation of OpenMosix is designed to run on clusters of X86/Pentium based workstations,both Ups and SMPs,that are connected by standard LANs.Possible configuration may range from a small cluster of PCs that are connected by 10Mbps Ethernet ,to a high performance system,with a large number of high-end,Pentium-based SMP servers that are connected by Gigabit LAN or Myrinet
