A Chinese Computer has the Edge

The recently published list of the 500 most powerful computer makes this time a Chinese computer – the Tianhe-2 brings it to 33.86 petaflops/second

Twice a year, in June and in November, creating the universities of Mannheim and Tennessee along with the Lawrence Berkeley National Laboratory, a list of the 500 most powerful computer in the world – of geeks around the world each time eagerly awaited. The latest list – published on just taking place in Leipzig 2013 International Supercomputing Conference – dominates a Chinese computer.

At No. 1 – a Chinese

The Tianhe-2 (German: Milky Way-2) creates incredible 33.86 petaflops, which are 34 quadrillion calculations per second. A trillion is a number with 15 zeros. Such a huge number beyond the human imagination. For comparison: On Earth live about 7 billion people – a quadrillion people would require no less than 150,000 earth. The second-placed hosts in the supercomputer list, a titanium Cray XK7 the U.S. Department of Energy at Oak Ridge (Tennessee), creates just 17.59 petaflops per second, slightly more than half of China’s new record holder. Just last November, the titanium Cray XK7 had led the list of the most powerful computers.

Five years ago, appeared for the first time a computer in the list, which managed more than one petaflop, the Roadrunner from IBM at the Los Alamo’s Laboratory, also at the U.S. Department of Energy – on his new list are however already 26 computers this class. The first Top 500 list Supercomputer in June 1993, exactly 20 years ago, led to the manufacturer’s Thinking Machine Corporation, a CM-5/1024. He also was in Los Alamo’s and then brought it to gigantic 59.7 gigaflops (billion operations) per second – in 2013 creates the perfectly ordinary every field, forest and meadow latest design computer as you have him standing straight on her desk.

Where are the most powerful computers available?

Most of the supercomputer, namely 253, is in the United States, followed by China with 65 supercomputers (plus another in Hong Kong, which is counted separately), Japan with 30 and the U.K. with 29 computers. France and Germany come to 23 to 19 supercomputers – in June 2000 were still to be found among the first 65 500 computers from Germany.

The winner consumes as much electricity as 320,000 households

New records set even when the computer power consumption – the Tianhe-2 requires almost about 18 megawatts, which is enough for about 320,000 German households in China, probably for a multiple thereof. But even these numbers fool you: In fact, the energy consumption decreases for years: To bring about the Sequoia ranked 3 out of a kilowatt of electricity more than two gigaflops out, making it probably the most energy-efficient computers in the world. What’s next with the development? According to the Moore’s Law, the processing power doubles about every 18 months. The next step would be the Escalops, corresponding to 1000 petaflops. Computer experts suggest that this new magic number in 2019 is achieved.
