Nvidia announced a personal supercomputer to run number crunching computing task. This computer is up to 250 times faster than standard PCs and workstations. The NVIDIA Tesla Personal Supercomputer is based on NVIDIA CUDA parallel computing architecture and powered by up to 960 parallel processing cores.
Yet another Linux success story; From the article:
The Philippine government’s official weather service, PAGASA, has replaced its SGI supercomputer with a clustered Debian Linux system that can process information vital to protection against typhoons, floods, droughts, tsunamis and other wild weather conditions at a fraction of the cost.
The cluster includes eight PCs running as a single node, connected via a gigabit switch, each with dual 64-bit Intel Xeon processors running the Debian Linux OS.

M. Shuaib Khan has published a list of open-source cluster management systems.
Personally, I had used openMosix and Red Hat Cluster software (which is also based upon open source software funded by Red Hat).
From the article: In computing world, the term “cluster” refers to a group of independent computers combined through software and networking, which is often used to run highly compute-intensive jobs. With a cluster, you can build a high-speed supercomputer out of hundreds or even thousands of relatively low-speed systems. Cluster management software offers an easy-to-use interface for managing clusters, and automates the process of queuing jobs, matching the requirements of a job and the resources available to the cluster, and migrating jobs across the cluster:
