A computer called Titan, which is 10 times more powerful than the last
lab machine, has claimed the title of the world's most powerful
Titan uses microchips more usually used for
video-gaming to crunch numbers for climate studies, models of advanced
materials and alternatives to petrol.
The machine has seized the
top spot in the Top500 - a closely-watched global league of the fastest
supercomputers, the Telegraph reported.
Built by Cray at the US
government's Oak Ridge National Laboratory in Tennessee, Titan is 10
times more powerful than the lab's last supercomputer, Jaguar, which led
the world as recently as 2009.
Titan was measured at 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
It had reclaimed the crown for the United States earlier this year from the K supercomputer in Japan, the report said.

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.
