Fastest supercomputer to be built
IBM's Blue Gene/L supercomputer
Currently, BlueGene/L is the most powerful computer in the world
Computer giant IBM will build the world's most powerful supercomputer at a US government laboratory.
The machine, codenamed Roadrunner, could be four times more potent than the current fastest machine, BlueGene/L, also built by IBM.
The new computer is a "hybrid" design, using both conventional supercomputer processors and the new "cell" chip designed for Sony's PlayStation 3.
Roadrunner will be installed at the Los Alamos Nation
