A US military supercomputer built with Sony PlayStation parts is now the world’s fastest computer. The IBM machine, affectionately dubbed “The Roadrunner,” is more than two times as fast as the previous supercomputer holding processing records for calculation speeds; the Roadrunner is capable of carrying out 1.026 quadrillion calculations per second. The project, which cost IBM $133 million, will be used to monitor nuclear weapons as well as study climate change.  "This is equivalent to the four-minute mile of supercomputing," said Jack Dongarra, a computer scientist at the University of Tennessee.
"This gives us a window into a whole new way of computing. We can look at phenomena we have never seen before," said Michael R Anastasio, a physicist who is director of the Los Alamos National Laboratory (LANL) in New Mexico where the computer will be based.
