A Calculating Win for China’s New Supercomputer
China’s “Tianhe-2” (Milky Way 2) supercomputer took first place in one recent speed test, clocking in at 30 quadrillion calculations per second—about twice as fast as the best American machines. The U.S. still has more supercomputers than any other nation, but some experts say computer speed is a measure of a country’s scientific innovation, and worry the U.S. is lagging behind.
