China has used Intel and Nvidia technologies to build the world’s fastest supercomputer Tianhe-1A, at the National University of Defence Technology in Tianjin.
“The title has gone to China’s Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.
To reach such high speeds the machine draws on more than 7,000 graphics processors and 14,000 Intel chips.
[...] Tianhe-1A is unusual in that it unites thousands of Intel processors with thousands of graphics cards made by Nvidia.
The chips inside graphics cards are typically made up of small arithmetical units that can carry out simple sums very quickly. By contrast, Intel chips are typically used to carry out more complicated mathematical operations.
The machine houses its processors in more than 100 fridge-sized cabinets and together these weigh more than 155 tonnes.”
