China regains top spot on fastest supercomputer list

WASHINGTON,- A supercomputer developed by Chinese researchers was ranked on Monday as the world's fastest computing system, overtaking the former champion made by the United States.


According to TOP500, a project ranking the 500 most powerful computer systems in the world, Tianhe-2 developed by China's National University of Defense Technology, was capable of operating as fast as 33.86 petaflops per second.

It overtook Titan, installed at the U.S. Department of Energy's Oak Ridge National Laboratory, which is now ranked No. 2 with a performance of 17.59 petaflops per second.

Tianhe-2 marks China's return to the No. 1 position of the TOP500 list since November 2010, when Tianhe-1A was the top system. Tianhe-1A is now the No. 10 system on the list.

TOP500 editor Horst Simon, deputy director of the U.S. Lawrence Berkeley National Laboratory, described Tianhe-2 as being "a great accomplishment" for China.

Tihanhe-2 demonstrates that China can build a large system with a string component of domestically developed technology and shows China's strong technology investments in high-performance computing (HPC), Simon told Xinhua.

William Gropp, director of the Parallel Computing Institute at the University of Illinois Urbana-Champaign, held the same opinion. He said China's investment in HPC shows how serious China is about being among the leaders in 21st century technology.

Gropp said that the commitment of China to HPC, and in particular to the continued and sustained development of new and better systems, will ensure that China is an important player in HPC.

Sequoia, another supercomputer developed by the United States, dropped one position and is now the No. 3 system with a performance of 17.17 petaflops per second, followed by Japan's K computer with 10.51 petaflops per second, and Mira in the United States with 8.59 petaflops per second.

Overall, the United States is the leader in supercomputing systems, taking up more than half of the entries in the list. As a nation, China now holds the No. 2 position with 65 entries, ahead of Japan, Britain, France and Germany.

"The U.S. continues to be the leading country in HPC, but the gap is closing," said Simon. He said the worldwide HPC distribution may be changing in the next decade.

According to Simon, countries that still lag behind such as India or Brazil are expected to invest more heavily and China could become an exporter for HPC technology to developing countries.

"There are many potentially big changes ahead, as many countries continue to industrialize and then recognize the value of HPC," Simon added.

The TOP500 list, released twice a year since June 1993, is considered the authoritative ranking of the world's supercomputers.

Well, the way they make shows is, they make one show. That show's called a pilot. Then they show that show to the people who make shows, and on the strength of that one show they decide if they're going to make more shows.

Like you, I used to think the world was this great place where everybody lived by the same standards I did, then some kid with a nail showed me I was living in his world, a world where chaos rules not order, a world where righteousness is not rewarded. That's Cesar's world, and if you're not willing to play by his rules, then you're gonna have to pay the price.

You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... and only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.

You see? It's curious. Ted did figure it out - time travel. And when we get back, we gonna tell everyone. How it's possible, how it's done, what the dangers are. But then why fifty years in the future when the spacecraft encounters a black hole does the computer call it an 'unknown entry event'? Why don't they know? If they don't know, that means we never told anyone. And if we never told anyone it means we never made it back. Hence we die down here. Just as a matter of deductive logic.
