PlayStation 3 consoles can be turned to supercomputers

The U.S. Air Force is surely, prodding on the possibility and has proposed to buy 2,200 Sony PlayStation 3 video game consoles to use them as supercomputers.

The Air Force Research Laboratory in Rome, N.Y., is interested in the chip technology inside the PS3, specifically the Cell Broadband Engine Architecture, according a blog posted by Gartner analyst Andrea DiMaio. The Air Force is studying whether the PS3 chips could be a cost-effective technology for modernizing the military's high-performance computing systems.

Supercomputer experts at the Air Force already have 336 PS3 consoles hooked together in an experimental Linux-based cluster. Now they want 2,200 more to expand the research project. The laboratory evaluated chips from other vendors, such as IBM and Intel, but found the PS3 chips to be much cheaper.

An RFP-related document justified the purchase this way: "With respect to cell processors, a single 1U server configured with two 3.2 GHz cell processors can cost up to $8000, while two Sony PS3s cost approximately $600. Though a single 3.2-GHz cell processor can deliver over 200 GFLOPS, whereas the Sony PS3 configuration delivers approximately 150 GFLOPS, the approximately tenfold cost difference per GFLOP makes the Sony PS3 the only viable technology for HPC applications."

DiMaio said the Air Force's interest in the PS3 is in line with the trend towards the consumerization of IT. "This is a pristine example of how consumer technology can be used in pretty demanding government contexts, although still in an R&D rather than operational capacity," she wrote. The additional PS3s will allow the R&D community to expand its current capabilities and investigate other applications that require many more processors to perform real-time tasks
