Chinese supercomputer tops list of world's fastest
A new Chinese supercomputer has dethroned the country's Tianhe-2 from the top of a list of the 500 most powerful supercomputers in the world.
For the first time, the country has taken top spot without using US technology.
The newcomer, called Sunway TaihuLight, is twice as fast and three times as efficient as Tianhe-2.
