Hardware, software and funding limits mean it's not easy to make the fastest computers even faster. That's too bad for the industries that rely on them.
US Energy Department funds two huge machines that combine IBM and Nvidia chips with Mellanox networking. A further $100 million goes toward making faster next-gen supercomputers.
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.
Bioengineers at Stanford University have developed microchips based on the human brain that are more energy efficient and up to 9000 times faster than the typical PC.
One of the world's most powerful supercomputers has finally done what had seemed impossible: successfully modelled brain activity.
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.
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.
Big Blue is using the human brain as a template for breakthrough designs. Brace yourself for a supercomputer that's cooled and powered by electronic blood and small enough to fit in a backpack.
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.
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.
