The resulting system, with components purchased at retail prices, cost a little more than $50,000. Researchers at the supercomputing center believe the system may be capable of a half trillion operations a second, well within the definition of supercomputer, although it may not rank among the worlds 500 fastest supercomputers.
Perhaps the most striking aspect of the project, which uses the open-source Linux operating system, is that the only hardware engineering involved was placing 70 of the individual game machines in a rack and plugging them together with a high-speed Hewlett-Packard network switch. The centers scientists bought 100 machines but are holding 30 in reserve, possibly for high-resolution display application.
"It took a lot of time because you have to cut all of these things out of the plastic packaging," said Craig Steffen, a senior research scientist at the center, who is one of four scientists working part time on the project.
The scientists are taking advantage of a standard component of the PS2 that was originally intended to move and transform pixels rapidly on a television screen to produce lifelike graphics. That chip is not the PlayStation 2s MIPS microprocessor, but rather a graphics co-processor known as the Emotion Engine. That custom-designed silicon chip is capable of producing up to 6.5 billion mathematical operations a second.
