China’s Tianhe-1A supercomputer, capable of carrying out more than 2,507 trillion calculations a second (2.507 petaflops), is claimed to be the most sophisticated supercomputer ever built. Made with more than 7,000 graphics processors and 14,000 Intel chips, the supercomputer is performs almost twice (47% faster) the speed of the next fastest supercomputer, XT5 Jaguar at the Oak Ridge National Laboratory (ORNL) in the US, that can carry out 1.75 petaflops per second.
The supercomputer is located in China’s National Center for Supercomputing in Tianjin. It is operational and currently works for the local weather service and the National Offshore Oil Corporation. The processors are kept in 103 refrigerated cabinets weighing a total of more than 155 tonnes.
The US is still the leader in having most supercomputers with more than half of the world’s top 500 supercomputers. Japan is told to be developing another machine, named K Computer, to be faster than Tianhe-1A. (source – Nvidia)
