US supercomputer Titan has regained the world's fastest computer spot following a massive upgrade.
Titan has leapfrogged previous holder IBM's Sequoia (used for nuclear simulations) by using a combination of GPU and CPU power meaning the machine now has 18,688 Nvidia Tesla K20x GPU modules working in conjunction with its pre-existing CPUs. The CPUs are designed to carry out single instructions whilst the massive parallelism of the GPUs boosts performance to an incredible 17.59 petaflop/sec according to the Linpack benchmark.
