A Chinese scientific research center has built the fastest supercomputer ever made, replacing the United States as maker of the swiftest machine, and giving China bragging rights as a technology superpower.

The Tianhe-1A computer in Tianjin, China, links thousands upon thousands of chips.

The computer, known as Tianhe-1A, has 1.4 times the horsepower of the current top computer, which is at a national laboratory in Tennessee, as measured by the standard test used to gauge how well the systems handle mathematical calculations, said Jack Dongarra, a University of Tennessee computer scientist who maintains the official supercomputer rankings.

Although the official list of the top 500 fastest machines, which comes out every six months, is not due to be completed by Mr. Dongarra until next week, he said the Chinese computer “blows away the existing No. 1 machine.” He added, “We don’t close the books until Nov. 1, but I would say it is unlikely we will see a system that is faster.”

Officials from the Chinese research center, the National University of Defense Technology, are expected to reveal the computer’s performance on Thursday at a conference in Beijing. The center says it is “under the dual supervision of the Ministry of National Defense and the Ministry of Education.”

The race to build the fastest supercomputer has become a source of national pride as these machines are valued for their ability to solve problems critical to national interests in areas like defense, energy, finance and science. Supercomputing technology also finds its way into mainstream business; oil and gas companies use it to find reservoirs and Wall Street traders use it for superquick automated trades. Procter & Gamble even uses supercomputers to make sure that Pringles go into cans without breaking.

And typically, research centers with large supercomputers are magnets for top scientific talent, adding significance to the presence of the machines well beyond just cranking through calculations.

Over the last decade, the Chinese have steadily inched up in the rankings of supercomputers. Tianhe-1A stands as the culmination of billions of dollars in investment and scientific development, as China has gone from a computing afterthought to a world technology superpower.

“What is scary about this is that the U.S. dominance in high-performance computing is at risk,” said Wu-chun Feng, a supercomputing expert and professor at Virginia Polytechnic Institute and State University. “One could argue that this hits the foundation of our economic future.”

Modern supercomputers are built by combining thousands of small computer servers and using software to turn them into a single entity. In that sense, any organization with enough money and expertise can buy what amount to off-the-shelf components and create a fast machine.

The Chinese system follows that model by linking thousands upon thousands of chips made by the American companies Intel and Nvidia. But the secret sauce behind the system — and the technological achievement — is the interconnect, or networking technology, developed by Chinese researchers that shuttles data back and forth across the smaller computers at breakneck rates, Mr. Dongarra said.

“That technology was built by them,” Mr. Dongarra said. “They are taking supercomputing very seriously and making a deep commitment.”

The Chinese interconnect can handle data at about twice the speed of a common interconnect called InfiniBand used in many supercomputers.

For decades, the United States has developed most of the underlying technology that goes into the massive supercomputers and has built the largest, fastest machines at research laboratories and universities. Some of the top systems simulate the effects of nuclear weapons, while others predict the weather and aid in energy research.

In 2002, the United States lost its crown as supercomputing kingpin for the first time in stunning fashion when Japan unveiled a machine with more horsepower than the top 20 American computers combined. The United States government responded in kind, forming groups to plot a comeback and pouring money into supercomputing projects. The United States regained its leadership status in 2004, and has kept it, until now.

At the computing conference on Thursday in China, the researchers will discuss how they are using the new system for scientific research in fields like astrophysics and bio-molecular modeling. Tianhe-1A, which is housed in a building at the National Supercomputing Center in Tianjin, can perform mathematical operations about 29 million times faster than one of the earliest supercomputers, built in 1976.

For the record, it performs 2.5 times 10 to the 15th power mathematical operations per second.

Mr. Dongarra said a long-running Chinese project to build chips to rival those from Intel and others remained under way and looked promising. “It’s not quite there yet, but it will be in a year or two,” he said.

He also said that in November, when the list comes out, he expected a second Chinese computer to be in the top five, culminating years of investment.

“The Japanese came out of nowhere and really caught people off guard,” Mr. Feng said. “With China, you could see this one coming.”

Steven J. Wallach, a well-known computer designer, played down the importance of taking the top spot on the supercomputer rankings.

“It’s interesting, but it’s like getting to the four-minute mile,” Mr. Wallach said. “The world didn’t stop. This is just a snapshot in time.”

The research labs often spend weeks tuning their systems to perform well on the standard horsepower test. But just because a system can hammer through trillions of calculations per second does not mean it will do well on the specialized jobs that researchers want to use it for, Mr. Wallach added.

The United States has plans in place to make much faster machines out of proprietary components and to advance the software used by these systems so that they are easy for researchers to use. But those computers remain years away, and for now, China is king.

“They want to show they are No. 1 in the world, no matter what it is,” Mr. Wallach said. “I don’t blame them.”

A significant progress, but boasting of wresting title (what kind of title?) is a thoroughly unrealistic over-optimism.

We built many supercomputers and every time a new one is introduced, everyone complains about the lack of time available for use on them and how few there are. So we're building a new generation of supercomputers and no doubt the complaints will be back with them too. It never ends.

Is your point -- because of the complaints -- Americanese are not interested in building the Supercomputer anymore ?

Or your point -- because of the complaints -- Americanese are not capable in building the Supercomputer anymore ?

-----------------------------

In China, if one (TIANHE 1A) shows up, then 100 more get build in no time.

Americanese can do the above too -- if starting from clueless dimwit Alzheimer Reagan to clueless dimwit George Bush Junior (Dubya), Chenyshyt, Rumsfeldstein and his neocons thugs had not insidiously swindled Americanese tax payer money to enrich the super wealthy Americanese with those super idiotic tax cut. :lol: :rofl:

... ... Jaguar is now in a cloud of dust as China's new supercomputer blows right past. Just yesterday at the Annual Meeting of National High Performance Computing in Beijing, the supercomputer was unveiled for all to see; fully functional and ready for business.

:banana: :pepper:
The $88 Million, Tianhe-1A (meaning Milky Way) computer uses 7,168 Nvidia Tesla M2050 GPUs, 14,336 Intel Zeon CPUs stacked into 103 different cabinets weighs over 150 tons & consumes just over 4 total megawatts of power.

All those numbers working together means that it is 1.4 times faster than Jaguar. The new Chinese Supercomputer is capable of a sustained computing environment of 2.507 petaflops. ... ...

Please update your information.

Tianhe-1a is faster than the second place Jaguar which has 1.759PFlops.

There is no way TSUBAME has 2.391PFlops.
Japan has no supercomputers in the top 20 list.

I think we should wait until the new Top 500 is published in this month. Maybe there is already a competitor in the USA.

USA is doing fine with Supercomputers.
^^

:hahaha::rofl:


--------------------------------------------------------------------------------

Do we believe the opinion of Expert Insiders (Mr Jack Dongarra, a professor of computer science at the University of
Tennessee and a distinguished research staff member at Oak Ridge National Laboratory) --- or do we believe the
opinion of beer drinking pedestrian John Blow and Jane Blow on the street??

--------------------------------------------------------------------------------

1) CHINA -- TIANHE 1_A --- Installation Date: (2010_OCT) --- Power Usage = 4.04 Mega Watts
--- Peak Performance = 4.701 petaflops
--- Sustained Performance = 2.507 petaflops

1b) CHINA -- TIANHE 1 --- Installation Date: (2009_MAY) --- Power Usage = unspecified
--- Peak Performance = 1.206 petaflops
--- Sustained Performance = 0.563 petaflops


2) USA -- CRAY JAGUAR XT5 --- Installation Date: (2009_NOV) --- Power Usage = 7.14 Mega Watts
--- Peak Performance = 2.331 petaflops
--- Sustained Performance = 1.759 petaflops


3) CHINA -- DAWNING NEBULAE --- Installation Date: (2010_MAY) --- Power Usage = unspecified
--- Peak Performance = 2.9843 petaflops
--- Sustained Performance = 1.271 petaflops


4) USA -- IBM ROADRUNNER --- Installation Date: (2008_JUN) --- Power Usage = unspecified
--- Peak Performance = 1.3757 petaflops
--- Sustained Performance = 1.042 petaflops


--------------------------------------------------------------------------------

Do take note on the (Installation Date) and (Model Number) ?
What do the above imply?


Within 5 months, China Engineers and Scientists have increase the (Peak Performance) by 157%
Within 5 months, China Engineers and Scientists have increase the (Sustained Performance) by 197%.


It means China Engineers and Scientists are improving extremely fast on the raw (Peak Performance) of the
Supercomputer, while at the same time China Engineers and Scientists are improving even faster on the
efficiency (Sustained Performance) of the machine.

If there is TIANHE 1_A, then TIANHE 1_B, and TIANHE 1_C are close around the corner.
:cheer: :colgate:


The well informed Earth citizens know that China as a country is progressing at super breakneck speed as
compare to the (Republican induced) slow super gridlock pace of USA.

By the time , the next CRAY or IBM supercomputer rolls around, the TIANHE_1B may have
already churning data at the speed of (Peak Performance = 10+ petaflops),
--- and TIANHE_2 (Peak Performance = 30+ petaflops) is waiting on the wing.

--------------------------------------------------------------------------------

BTW, we all know that Americanese USA had already imposed total embargo on selling all top notch HiTech products
to China for a long long time, because the Americanese USA who has been treating China as the Big Time Enemy,
want to keep China weak militarily forever.


NOTE: At the same time, we all know that Americanese USA are hypocritically accusing China of NOT importing enough from USA.

:gossip:
Given the above situation, --- do I hear that -- some Americanese around USA are quietly whispering that maybe
China stole the secret of building Supercomputer from someone in Americanese DOE (Department of Enegy)
who conveniently has access to this Supercomputer Secrets??

:eek2:
someone in Americanese DOE = Head Honcho Secretary of Energy = who else but (Steven Chu, who has China blood running on his vein)


:jk:
JOKE: I surely hope, the FBI and Homeland Security are working harder than ever to hunt down the China Trojan Spies
(Scientists & Engineers) all around USA that may had stolen the secrets and gave the knowledge to China.

:carrot: :pepper: :rofl:

Is China building much better Supercomputer than USA -- just a one-off stunt?


Is this just a one-off stunt?

It seems unlikely. Unlike Japan, which created a stir (and helped stir U.S. development) by
creating a supercomputer that briefly held the world's top spot in 2002,

China seems devoted to making ever-faster machines.



The developments in Tianjin are "part of a multi-year strategy by
China to develop a range of machines to create a dominant position in both military and commercial applications."




So should the U.S. be worried?

Jack Dongarra, who helps oversee the supercomputer in Tennessee, says we should. "This is a wake-up call,"
China definitely welcome the Supercomputer race with the Americanese USA.
In this Supercomputer field, USA has a chance to compete with China.

:badnews:
Unlike the HST (Hi Speed Train) field, where USA has absolutely ZERO chance to compete in terms of Brainpower and Money.


Printing money (USD) like a madman, will not solve the USA economic impotency.
US Fed Bernanke believes Printing US Dollar = Free Viagra for US economy.

:horse:
Then again maybe Americanese Trojan Horse traitors in China (those who support Liu Xiaobo)
will deliver the the economic Viagra for USA by exchanging their RMB savings into USD.
