Gary's openMosix Floppy (GoMF) is a single floppy openMosix Linux mini-distro designed to quickly add CPU/Memory resources to an openMosix cluster.

The floppy uses:

• Linux 2.4.24-om
• BusyBox
• Openmosix-tools-0.3.6-2
• replimenu

The floppy includes the auto discovery daemon and some user tools like mosctl, mosrun, mosmon, mps, setpe.

There is a simple menu system using replimenu for starting and stopping the openMosix services as well as changing the IP address etc. By default the IP address is acquired by DHCP.

The kernel supports several network card inline (mainly 10/100 BaseT) and I am just starting on a optional supplemental disk with modules for other network cards.

To be really effective this set up needs an established openMosix node, but I think this disk helps add extra CPU/Memory resources with just single floppy.

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.
