Nvidia, which got its start making processors for computer game enthusiasts, has won another victory for parrallel computing with the inclusion of its graphics chips in what is expected to be the world’s fastest supercomputer.

The Titan computer being built for the Oak Ridge National Laboratory in Oak Ridge, Tenn should boast a record 20 petaflops of peak performance — that’s about 20 million billion math operations per second.

By the time it is complete in 2013, the computer will be driven by 18,000 Nvidia graphic processor units, or GPUs, along with an equivalent number of central processors made by rival Advanced Micro Devices.

Keenly aware of explosive growth in tablets, smartphones and cloud computings, Nvidia is looking beyond its core business of designing chips that make games and videos look better on PCs.

As well as making sleek chips for smartphones, Nvidia isĀ  promoting its graphics technology to be used for for new purposes, including supercomputers running simulations in astrophysics and other math-heavy tasks.
