Build your own desktop-supercomputer

In January 2007, two of us (professor Joel Adams and student Tim Brom) decided to build a personal, portable Beowulf cluster. Like a personal computer, the cost had to be low -- our budget was $2500 -- and its size had to be small enough to sit on a person's desk. Joel and Tim named their system Microwulf, which has broken the $100/GFLOP barrier for double precision, and is remarkably efficient by several measures. You may also want to take a look at the Value Cluster project for more information on $2500 clusters.

As of August 2007, the price to construct the cluster with the same hardware would be $1,255.80
