8.2 quadrillion calculations per second
The world’s most powerful computer is now at the Riken Advanced Institute for Computational Science in Japan
According to The New York Times, the computer, called “K,” is three times faster than the next fastest computer, a Chinese computer, Tianhe-1A, that previously held the highest spot. K, built by Fujitsu, can make 8.2 quadrillion calculations each second. “K” stands for “Kei,” meaning 10 quadrillion, or the number of calculations per second researchers hope K will one day be able to perform per second. K’s abilities are the equivalent of linking one million desktop computers.
K is made out of 672 computer racks, with 68,544 computer processing units (CPUs) but the lab plans to raise that number to 800 racks, a move that will make the machine even speedier and more powerful.
