Playstation 3 cluster

The considerable computing capability of the PlayStation 3 has raised interest in using multiple, networked PS3s for various purposes.cite web|url=http://www.consolewatcher.com/2006/08/building-supercomputer-using-playstation-3|title=Building Supercomputer Using Playstation 3|publisher=Console Watcher.com|date=2006-08-28|accessdate=2006-08-28]

PS3 Clusters

The NCSA has already built a cluster based on the PlayStation 2.

On January 3 2007, Dr. Frank Mueller, Associate Professor of Computer Science at NCSU, clustered 8 PS3s. Mueller commented that the 512 MB of system RAM is a limitation for this particular application, and is considering attempting to retrofit more RAM. Software includes: Fedora Core 5 Linux ppc64,MPICH2, OpenMP v2.5, GNU Compiler Collection and CellSDK 1.1.

Single PS3

Even a single PS3 can be used to significantly accelerate some computations. Marc Stevens, Arjen K. Lenstra, and Benne de Wegerhave demonstrated using a single PS3 to calculate perform an MD5 hash attack in a few hours. They say:"Essentially, a single PlayStation 3 performs like a cluster of 30 PCs at the price of only one" [ [http://www.win.tue.nl/hashclash/Nostradamus/ Nostradamus ] ]

Using the PS3 to Help Medical Research

On March 22 2007, SCE and Stanford University expanded the Folding@home project to the PS3. [cite web|url=http://www.scei.co.jp/folding/en/|title=Folding@home|publisher=Sony Computer Entertainment|accessdate=2007-03-18] Along with thousands of PCs already joined over the Internet, PS3 owners are able to lend the computing power of their game systems to the study of improper protein folding and associated diseases, such as Alzheimer's, Parkinson's, Huntington's, cystic fibrosis, and several forms of cancer. The software was included as part of the 1.6 firmware update (March 22, 2007), and can be set to run manually or automatically when the PS3 is idle through the Cross Media Bar. The processed information is then sent back to project's central servers over the Internet. Processing power from PS3 users is greatly contributing to the Folding@home project, and PS3s have overtaken all other participating operating systems in teraflops contributed. [cite web|url=http://www.gamepro.com/news.cfm?article_id=107328|title=PS3 doubles Folding@Home's processing power] [cite web|url=http://fah-web.stanford.edu/cgi-bin/main.py?qtype=osstats|title=Folding@Home - Client statistics by OS|publisher=Stanford University| accessdate =] As of April 23 2007, more than 250,000 PS3 owners have allowed the Folding@home software to be run on their systems, averaging over 400 teraFLOPS and peaking at over 700. By comparison, the world's most powerful supercomputer, Blue Gene has a peak performance of 280.6 teraFLOPS. [cite web |url=http://news.bbc.co.uk/1/hi/technology/6594907.stm |title=PS3 boosts protein research plan
accessdate=2007-04-26 |author=BBC News |date=2007-04-26] Latest report stated that Folding@Home has past 1PF (petaFLOPS) mark, of which 800TF(teraFLOPS) are supplied by PlayStation 3.

The [http://cbbl.imim.es:8080/cbbl Computational Biochemistry and Biophysics Lab] in Barcelona has launched a distributed computing project called [http://www.ps3grid.net/PS3GRID/ PS3GRID] . This project is expected to run sixteen times faster than an equivalent project on a standard PC. Like most distributed computing projects, it is designed to run only when the computer is idle.
