The pace of performance increases has slowed among the world's fastest supercomputers, while China now has nearly as many as the UK, France, and Germany combined.
Tianhe-2, with 3.1 million processor cores and a lot of Chinese-build technology, is the new leader of the twice-yearly list of the world's 500 fastest supercomputers.
Calculation's what you need if you want to be a record breaker -- 2,507 trillion calculations every second, to be precise, which is how many sums the newly crowned world's fastest supercomputer can do.
Harnessing more than 82,000 processors on the world's fourth-ranked supercomputer, scientists run an experiment that represents 1 percent of human brain activity.
The latest list of most-powerful computers is a bit of same old, same old. But soon, it won't be so easy to get ahead on the Top500 list by plugging in special-purpose accelerator cards.
Cray XT5 supercomputer known as "Jaguar" finally bests IBM after three tries. The top 10, while still dominated by supercomputers housed in the U.S., had just one newcomer.
The fastest got faster, as the K Computer topped its own record on the twice-yearly supercomputer speed test by scoring 10.51 quadrillion calculations per second.
Jack Dongarra, an expert at the University of Tennessee, discusses the potential threat China poses with its new supercomputer and the state of supercomputing in the U.S.
