WASHINGTON nike air more uptempo australia , June 19 (Xinhua) -- China's Sunway TaihuLight and Tianhe-2 are still the world's fastest and second fastest machines, but America's Titan was squeezed into fourth place by an upgraded Swiss system, according to the latest edition of the semiannual T0P500 list of supercomputers released Monday.

Sunway TaihuLight, described by the T0P500 list as "far and away the most powerful number-cruncher on the planet," maintained the lead since last June, when it dethroned Tianhe-2 nike cortez suede australia , the former champion for the previous three consecutive years.

It means that a Chinese supercomputer has topped the rankings maintained by researchers in the United States and Germany for nine times in a row.

What's more, Sunway TaihuLight, with a performance of 93 petaflops, was built entirely using processors designed and made in China.

"It highlights China's ability to conduct independent research in the supercomputing field," Haohuan Fu, deputy director of the National Supercomputing Center nike cortez flyknit australia , where Sunway TaihuLight was installed, told Xinhua.

"China is simultaneously developing hardware and software technologies of supercomputers," Fu said. "It is expected that rapid development in homegrown hardware technologies, supported by homegrown software, will lead to a stronger research and engineering test capacity in many fields, thus promoting an industrial upgrading and nike cortez leather australia , eventually, a sustainable development of China's homegrown supercomputing industry."

Tianhe-2, capable of performing 33.9 petaflops, was based on Intel chips, something banned by the U.S. government from selling to four supercomputing institutions in China since 2015.

In the latest rankings, the new number three supercomputer is the upgraded Piz Daint nike cortez kenny 1 australia , a system installed at the Swiss National Supercomputing Center.

Its current performance of 19.6 petaflops pushed Titan, a machine installed at the U.S. Oak Ridge National Laboratory, into fourth place. Titan's performance of 17.6 petaflops has remained constant since it was installed in 2012.

"This is the second time in the 24-year history of the TOP500 list that the United States has failed to secure any of the top three positions," the TOP500 organizers said in a statement.

The only other time this occurred was in November 1996, when three Japanese systems captured the top three spots.

"Nevertheless, the U.S. still claims five of the top 10 supercomputers nike cortez kenny 3 australia , which is more than any other nation," they said.

Fu called the upgraded Swiss system "really a surprise," saying that "it reflects the increased investment in large-scale supercomputers in Europe."

"Although the U.S. dropped out of the top three, it still has strong strength in high performance computing," Fu told Xinhua. "If everything goes well, we could see two U.S. systems with a performance of 200 to 300 petaflops in the next rankings at the end of the year."

Just days before the TOP500 announcement nike cortez ultra australia , the U.S. Department of Energy said it has awarded AMD, Cray, HP Enterprise, IBM, Intel and NVIDIA a total of 258 million U.S. dollars in funding to accelerate the development of next-generation supercomputers.

"Continued U.S. leadership in high performance computing is essential to our security, prosperity nike cortez nylon australia , and economic competitiveness as a nation," U.S. Secretary of Energy Rick Perry said in a recent statement.

The immediate goal of the United States is to develop at least one exascale-capable system by 2021, which will be at least 10 times faster than China's Sunway TaihuLight.

"Global competition for this technological dominance is fierce," the U.S. Department of Energy asserted. "However, the U.S. retains global leadership in the actual application of high performance computing to national security, industry nike cortez ultra moire australia , and science."

Indian police questioned an Uber executive Tuesday about the company's claim it conducts comprehensive background checks and a top official called for the taxi-booking service to be banned nationwide after one of its New Delhi drivers was accused of rape.

New Delhi police official Brijendra Kumar Yadav said there is a possibility of criminal charges against the company if police find evidence the taxi-hailing app misrepresented the safety of its service.

"What we are doing is trying to ascertain what knowledge Uber had of this person," Yadav said. It was the second day of questioning for Uber's general manager in India, Gagan Bhatia. Police were also investigating whether the driver may have presented false documents to Uber, according to Press Trust of India.

The driver, 32-year-old Shiv Kumar Yadav, is being held by police and will appear again in a New Delhi court on Thursday. A 26-year-old woman who hired Yadav for a ride home from a dinner engagement Friday night accused him of rape.

The case nike cortez grey australia , almost two years after a young woman was fatally gang raped on a bus in the capital, has renewed national anger over sexual violence in India and demands for more effort to ensure women's safety. It is also a blow for Uber, which has attracted praise and controversy around the world with a service based on hailing taxis from a smartphone app.

India's home minister called for all Indian states and territories to ban Uber following a ban on the service in New Delhi on Monday. Uber has faced restrictions in other countries after licensed taxi operators claimed the service was competing unfairly. Uber's drivers are independent contractors.
