All work and no play

Very cool -- from PhysOrg:
Engineer Creates First Academic Playstation 3 Computing Cluster
The Sony Playstation 3, Xbox and Nintendo Wii have captivated a generation of computer gamers with bold graphics and rapid-fire animation. But these high-tech toys can do a lot more than just play games. At North Carolina State University, Dr. Frank Mueller imagined using the power of the new PS3 to create a high-powered computing environment for a fraction of the cost of the supercomputers on the market.

Mueller, an associate professor of computer science, has built a supercomputing cluster capable of both high-performance computing and running the latest in computer gaming. His cluster of eight PS3 machines – the first such academic cluster in the world – packs the power of a small supercomputer, but at a total cost of about $5,000, it costs less than some desktop computers that have only a fraction of the computing power.

“Clusters are not new to the computing world,” Mueller says. “Google, the stock market, automotive design companies and scientists use clusters, but this is the first academic computing cluster built from Playstation 3s.
And what makes the Playstation3 so good as a scientific computer?
“Scientific computing is just number crunching, which the PS3s are very good at given the Cell processor and deploying them in a cluster,” Mueller says. “Right now one limitation is the 512 megabyte RAM memory constraint, but it might be possible to retrofit more RAM. We just haven’t cracked the case and explored that option yet.” Another problem lies in limited speed for double-precision calculations required by scientific applications, but announcements for the next-generation Cell processor address this issue.
The PS3 allows the Linux operating system to be installed, and IBM designed the programming environment for programming the Cell processor (including eight vectorization units), which combined tremendous computing power within a single PS3. According to Mueller, each PS3 unit contains six operational special-purpose cores for number crunching and one general-purpose core that is two-way multithreaded in his configuration, so the eight machines clustered have 64 logical processors, providing plenty of number-crunching ability in addition to running the latest games.
Clever solution to a big problem. Lots of uses outside of academia as well...
