China supercomputer world's fastest: report

A Chinese supercomputer is the fastest in the world, according to survey results announced Monday, comfortably overtaking a US machine which now ranks second.

Tianhe-2, a supercomputer developed by China's National University of , achieved processing speeds of 33.86 (1000 trillion calculations) per second on a benchmarking test, earning it the number one spot in the Top 500 survey of supercomputers.

The tests show the machine is by far the fastest computer ever constructed. Its main rival, the US-designed Titan, had achieved a performance of 17.59 petaflops per second, the survey's website said.

Five of the world's 10 fastest computers are installed in the US, the survey said, with the two in China, two in Germany and one in Japan.

The recognition of Tianhe-2, meaning Milky Way-2, as the world's fastest computer marks the return of the title to China after the machine's predecessor, the Tianhe-1 was ranked the world's fastest in November 2010, only to be overtaken by a machine from the US.

Unlike some of its Chinese predecessors, most of the Tianhe-2's parts are developed in China, except for its main , which are designed by US firm Intel.

"Most of the features of the system were developed in China...the interconnect, operating system, front-end processors and software are mainly Chinese," the list's website quoted editor Jack Dongarra as saying.

But the US still dominates the overall rankings, with 252 systems making the top 500. The number of European machines, at 112 systems remains lower than the number of Asian machines, at 119, the list's website said.

The supercomputers on the Top 500 list, which is produced twice a year, are rated based on speed of performance in a by experts from Germany and the United States.

Amazing what can be accomplished by scientists trained at Stanford, MIT, et al, using patents and technology stolen from everybody else, isn't it?

thieves do prosper sometimes.

Given that the majority of engineering students and faculty at Mit and Stanford are not Americans, i fail to see what Geokstr is whining about.

NASA of course was largely reliant on "stolen" rocket technology from Germany. American Physics was mostly stolen from German, Russian, and Japanese physicists.

America's textile industry was stolen from the British, and the entire American nation was stolen from Native Americans.

Poor Geokstr. All he has left is bitterness over the ongoing death of American society.

He has only his Conservative friends to blame for that.

I think that the US is based upon settlers from many nations and yes after WW2 the German scientist became the spoils of war. But if it wasn't for the American traders, transferring Nuclear technology to Russia and then to China, then the world would be a different story. China has not created anything, on its own, since paper and fireworks. Japan was destroyed and then built up to become a Asian giant. But why go back to say that Native Americans were the true Native Americans, history say's they came from the land bridge and crossed down from Canada, and the rest came up from South. So they fought and conquered other tribes and that's what has been going on for the last 3 thousand years in the Americas. Now to the technology that has allowed China to assemble the fastest super c for bragging rights, as a tech I believe the heart and soul of speed is still the American made processor. China has not generated a original idea in centuries. Now lets see what they do to better the world.

no you need to speak to the charges you made toward Geokstr. then when can talk about, need I continue. People always choose to ignore the context of the whole and speak to their a single point, which is only helped the closed society, not the world. lets start with your charges of stolen land and technology
