openMosix is a Linux kernel extension for single-system image clustering which turns a network of ordinary computers into a supercomputer for Linux applications.

openMosix Community:  Geek Girls They Call Themselves, Maya, Anu, Asmita, Snehal, Krushna, the developers of Migshm, are students of Cummins College of Engineering, University of Pune, India.  Migshm, the experimental openMosix Distributed Shared Memory patch, is available for test clusters and is showing great promise. Geek Girls, well judge for yourself.  If this is their first project, what great things will be next?

What is openMosix?
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. openMosix continuously attempts to optimize the resource allocation.

We achieve this with a kernel patch for Linux, creating a reliable, fast and cost-efficient SSI clustering platform that is linearly scalable and adaptive. 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. The cluster behaves much as does a Symmetric Multi-Processor, but this solution scales to well over a thousand nodes which can themselves be SMPs.

The openMosix Community is very active, contributing add-on applications and sharing helpful information with all users.  The openMosix Add-Ons and Community page lists these shared applications.  And, it is all GPL'd.

History
openMosix is the GPLv2, Open Source, project to extend the outstanding MOSIX project.  New releases of MOSIX became proprietary software in late 2001 and openMosix was begun February 10, 2002 by Moshe Bar to keep this highly regarded Linux Clustering solution available as open source.

openMosix quickly acquired an international team of volunteers that captured prior releases of the GPL code and started to immediately improve and extend the solution.  Users worldwide have adopted openMosix to protect their investments and extend their clustering operations.
