Meet Summit, worlds most powerful supercomputer built by the US

The United States has dethroned China after five years by unveiling the world's most powerful supercomputer, Summit. Summit is capable of operating at 200 petaflops which translates to 200 quadrillion calculations per second. In comparison, the previous record holder Sunway TaihuLight by China has a 93 petaflop capacity, Engadget reported.

The supercomputer is equipped with 4,608 servers, over 9,000 22-core IBM Power9 processors and more than 27,000 NVIDIA Tesla V100 GPUs. Summit has been already used for scientific calculations and upcoming projects include analysing exploding stars and crunching health data. 

According to recent reports, Japan also had plans to build the world's fastest-known supercomputer in a bid to arm the country's manufacturers with a platform for research that could help them develop and improve driverless cars, robotics and medical diagnostics. 

The Ministry of Economy, Trade and Industry will spend 19.5 billion yen ($173 million) on the previously unreported project, a budget breakdown shows, as part of a government policy to get back Japan's mojo in the world of technology. The country has lost its edge in many electronic fields amid intensifying competition from South Korea and China, home to the world's current best-performing machine. In a move that is expected to vault Japan to the top of the supercomputing heap, its engineers will be tasked with building a machine that can make 130 quadrillion calculations per second - or 130 petaflops in scientific parlance - as early as next year, sources involved in the project told Reuters.

At that speed, Japan's computer would be ahead of China's Sunway Taihulight that is capable of 93 petaflops. "As far as we know, there is nothing out there that is as fast," said Satoshi Sekiguchi, a director general at Japan's National Institute of Advanced Industrial Science and Technology, where the computer will be built. The push to return to the vanguard comes at a time of growing nostalgia for the heyday of Japan's technological prowess, which has dwindled since China overtook it as the world's second-biggest economy. Prime Minister Shinzo Abe has called for companies, bureaucrats and the political class to work more closely together so Japan can win in robotics, batteries, renewable energy and other new and growing markets.
