Gaurav Khanna with his Supercomputer at the University of Massachusetts
Your PlayStations are more powerful than you could ever imagine. I think we realized this when NASA announced that the most famous spacecraft of this generation, New Horizons, uses a hacked version of the CPU of an Original PlayStation. Another genius has used the power of the PlayStation to build a supercomputer.
A black hole physicist at the University of Massachusetts, Gaurav Khanna, has built a powerful supercomputer out of his PlayStation (PS3) consoleto aid him in his research on black holes. Gaurav aims to find the curvature of space-time caused by a violent event, such as the collision of two black holes.

His calculations exceeded the limit of a regular computer and so Khanna soon felt the need for a better machine. Since a supercomputer costs a fortune, he decided to build one. Supercomputers work on the general principle of interconnecting many computers together in a single network and Gaurav applied the same principle to PlayStations (PS3).
The university connected 16 Sony PlayStation consoles over the Internet and powered them with Linux. We already know that 496 of the world's top 500 supercomputers use Linux. This created a makeshift supercomputer that has a processing speed increased by almost 10 times.
The US Air Force followed Khanna's technique and built its own supercomputer using 1,760 gaming consoles for radar image processing in 2010.

He revealed his plans to build another supercomputer using PC graphics cards. This supercomputer is supposed to be as powerful as a computer made from 20 PS3s.
