Chinese supercomputer named world's fastest

The supercomputers on the Top 500 list, which is produced twice a year, are rated based on speed of performance

China overtook the United States at the head of the world of supercomputing on Sunday when a survey ranked one of its machines the fastest on the planet.

Tianhe-1, meaning Milky Way, achieved a computing speed of 2,570 trillion calculations per second, earning it the number one spot in the Top 500 (www.top500.org) survey of supercomputers.

The Jaguar computer at a US government facility in Tennessee, which had held the top spot, was ranked second with a speed of 1,750 trillion calculations per second.

Tianhe-1 does its warp-speed "thinking" at the National Centre for in the northern port city of Tianjin -- using mostly chips designed by US companies.

Another Chinese system, the Nebulae machine at the National Supercomputing Centre in the southern city of Shenzhen, came in third.

The still dominates, with more than half of the entries in the Top 500 list, but now boasts 42 systems in the rankings, putting it ahead of , France, Germany and Britain.

It is not the first time that the United States has had its digital crown stolen by an Asian upstart. In 2002, Japan made a machine with more power than the top 20 American computers put together.

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

Half of the computing power of this machine comes from Nvidia graphic co-processors, a company that will soon be owned by China.

And unlike America, the computing power of this machine will be used to design nuclear weapons.


how will nvidia be owned by china?

I agree with the second part though, I doubt that computer was made for useful science purposes

They don't need a supercomputer of this magnitude to make nuclear weapons. Could they use it to create more powerful nuclear weapons? Probably, I'm not a physicist, so I can't be sure though. I'm not worried however, because there is no point worrying about the creation of a weapon that can destroy the world ten times over when we already have weapons that can do it 5 times over. Once is enough to matter, and any weapons that are created will be no more of a threat to us than conventional WMD's.

Unless they want to design nukes that take out the entire Solar System, I'm sure this will be used in other more speculative fields; regardless if its related to Defense research.

It's not a matter of brute power but of sophistication these days. If you know what you are doing, you can tweak the output of those processes to produce different mix of effect - from nearly pure gamma-ray radiation bursts with little kinetic/heat output to relatively low levels of contamination with long-lived isotopes to not-so-powerfull but directed beam-like controlled explosions. This is where detailed modelling is advisable before you go ahead and evaporate your testing grounds with a faulty prototype.

Another obvious application of course is cryptography. Protein folding is another. There is no shortage of tasks waiting for this kind of computing power.

Actually I wrote the following...

"And unlike America, the computing power of this machine will not be used to design nuclear weapons."

Someone edited out the "NOT" part.

Gee, I wonder why....



Or you intended to write "not" and forgot. I believe the application of Occam's razor is needed here. We've all typed too quickly or just plain forgot to write a word. The theory that someone changed the comment is a little far fetched.

The other theory of course is thanks to the good old uncle Freud - you wrote what you actually meant but were afraid to admit (even to yourself).

If ibm simulated the brain of a cat with 1 of they "supercomputers" with this new machine the chinesse can simulate the brain of a scientist. You can not do proper research without proper tools. Technology produces even more technology.

2,570 trillion calculations per second is already outdated. By a couple of months it will be beaten by the VS. "Blue Waters" will be 4 times faster then Tianhe-1. And many others 10 Pflops systems will follow like "Sequoia" (IBM), "Project K" (Fujitsu), "Pleiades" (SGI and Intel) and so on...

I am inclined to believe it likely that this system will be used in China's advanced fusion power program rather than for military uses.
