World's fastest supercomputer belongs to China

China has now surpassed the United States for the fastest supercomputer in the world. A supercomputer is basically a bunch of computers strung together that are used for calculating and processing huge amounts of data at a time. The supercomputer, the Tianhe-1A, was unveiled at an annual technological meeting in Beijing, China. The Tianhe-1A system cost $88 million and with all the computers strung together it weighed an astounding 155 tons. The previous speed record holder was called the Cray XT5 Jaguar and it was located in a lab in Tennessee. A supercomputer's speed is recorded by how much data they can compute at once. The Tianhe-1A computed 2.507 petaflops and the U.S supercomputer calculated 1.75 petaflops.
