Xinhua News Agency, Washington, June 19th, the new world top 500 supercomputer list released on the 19th, China's super-calculation "Shenwei·Taihu Light" and "Tianhe No. 2" for the third time in a row, the top two, The US super-calculated "Titan" was pushed to the fourth by the Swiss "Dent Peak". This is the first time in 20 years that the United States has fallen out of the top three.
The Global Top 500 list is released semi-annually. China’s super-calculation “Shenwei·Taihu Light†won the first time with a floating-point operation rate of 930 billion times per second a year ago. It was described by the list of editors as “the most powerful digital operation on the planet.†machine". Its core components are all made in China.
Fu Xin, deputy director of China National Supercomputing Wuxi Center and associate professor of Tsinghua University, told Xinhua News Agency that China's domestically produced system has won the world's first place for three consecutive times, highlighting China's independent research and development capabilities in the field of supercomputers.
He said that China's supercomputer is improving in both hardware and software development. It is expected that the domestically developed hardware that will develop rapidly in the future will bring more powerful scientific research capabilities and engineering test capabilities to various fields under the support of domestic software.
China National University of Defense Technology's "Tianhe No. 2" floating-point operation speed is 339 billion times per second, this time is still ranked second. The US "Titan" ranking has followed the "Tianhe No. 2" many times, but this time, the Swiss National Computing Center's "Dente Peak" has been upgraded to a floating point operation speed of 196 million times per second. Eighth year ago, the eighth place rose to the third place now. Since the list in 2012, Titan has maintained a computing speed of 176 million times per second without change, ranking from the third to the fourth.
The international TOP500 organization said in a statement that this is the second time in the history of the world's top 500 supercomputers in the United States for the second time. The first time was in November 1996, when three Japanese systems occupied the top three positions. However, among the top ten in this list, the United States still occupies 5 seats, more than other countries.
Fu said that the accumulation of the United States cannot be ignored. If nothing else, there will be two new systems in the US that will be 20 billion to 30 billion times per second in the year-end ranking. The Swiss system's top three are indeed quite unexpected, showing the increase in European investment in large-scale super-computing systems.
Among the top 500 list, the total number of systems in the US ranked first, reaching 169, and China ranked second with 159. However, compared with the number of 171 units listed each other half a year ago, the share of both countries has decreased.
The list of the world's top 500 supercomputers began in 1993 and is a well-known list of installed supercomputers in the world. It is jointly compiled by US and German supercomputer experts. On the eve of the launch of the list, the US Department of Energy announced that it will allocate a total of 258 million US dollars to six companies in the next three years, aiming to develop at least one calculation per second by 2021. Supercomputer system. China, Japan and Europe have also announced a multi-billion-dollar calculation plan. Experts predict that the top position of the future top 500 list may be dominated by multiple countries.
