Supercomputer Titan has claimed the title of the world's most powerful supercomputer in the Top500 - a global league of the fastest supercomputers. Titan uses microchips used in video-gaming to crunch numbers for climate studies and making models of advanced materials.
Built by Cray at the US government's Oak Ridge National Laboratory, Tennessee, Titan has a processing capacity of 17.59 petaflops - or 17.59 thousand trillion calculations per second - beating the previous record of 16.32 petaflops held by Sequoia, a supercomputer at Lawrence Livermore National Laboratory in California, which simulates nuclear attacks.
It had reclaimed the crown for the USA earlier from the K supercomputer in Japan. The new champion contains almost 19,000 processing nodes and 710 terabytes of memory as well as a 16-core AMD CPU.
Supercomputers are increasingly incorporating GPUs, which consume less power for more processing power compared to CPUs because their "parallel" architecture allows them to perform many calculations at once.
