SEOUL, South Korea - Leaders of 20 major economies on Friday refused to endorse a US push to get China to let its currency rise, keeping alive a dispute that has raised the specter of a global trade war.
At the end of their two-day summit, the leaders of the Group of 20 rich and developing economies -- including US President Barack Obama and Chinese President Hu Jintao -- issued a statement that only said they agreed to refrain from "competitive devaluation" of currencies.

Such a statement is of little consequence since countries usually only devalue their currencies in extreme situations like a severe financial crisis. Using a slightly different wording favored by the US -- "competitive undervaluation" -- would have shown the G20 taking a stronger stance on China's currency policy.

The crux of the dispute is Washington's allegations that Beijing is artificially keeping its currency, the yuan, weak to gain a trade advantage. But the US position has been undermined by its own recent policy of printing money to boost a sluggish economy, which is weakening the dollar. 


Many countries are irate over the Federal Reserve's plans to pump $600 billion into the sluggish American economy. They see that move as a reckless and selfish scheme to flood markets with dollars, driving down the value of the US currency and giving American exporters an advantage.
Some critics warn that US interest rates kept too low for too long could inflate new bubbles in the prices of commodities, stocks and other assets. Developing countries like Thailand and Indonesia fear that falling yields on US government bonds will send money flooding their way in search of higher returns. Such emerging markets could be left vulnerable to a crash if investors later decide to pull out and move their money elsewhere.
Still, the leaders vowed to fight protectionism.
"Recognizing the importance of free trade and investment for global recovery, we are committed to keeping markets open and liberalizing trade and investment," the joint statement said.
The G20 leaders also said they will pursue policies to reduce the gaps between nations running large trade surpluses and those running deficits.
The G20 Seoul Summit has confirmed the 6-percent shift of quota shares to emerging economies in the International Monetary Fund, according to the joint communique.

"Today, we welcomed the ambitious achievements by the Finance Ministers and Central Bank Governors at the Gyeongju Meeting and subsequent decision by the IMF, on a comprehensive package of IMF quota and governance reforms," said the communique.

The reform are an important step toward a more legitimate, credible and effective IMF, by ensuring that quotas and Executive Board composition are more reflective of new global economic realities, it said.
The IMF reform, it said, would continue the dynamic process aimed at enhancing the voice and representing of emerging market and developing countries, including the poorest, through a review of the quota formula by January 2013.

And the next general review of quotas would be completed by January 2014, it said.

China sees positive results at G20 Seoul summit

SEOUL - The Group of 20 (G20) summit that ended Friday has achieved positive results with concerted efforts from all participating nations, Chinese delegation spokesman Ma Zhaoxu said.

Ma said that the world economy is gradually recovering, but uncertainties still remain, and that the Seoul summit witnessed the framework of G20 shifting its focus from emergency response to long-term economic governance. 
Firstly, all member countries vowed to strengthen the role of the G20, and properly deal with the new risks and new challenges in the international financial sector so as to jointly boost the positive, sustainable and balanced growth of the global economy, Ma said.
Secondly, G20 leaders agreed to further promote reform of international financial institutions, and confirmed the 6-percent shift of quota shares to emerging economies in the International Monetary Fund, he said.
Thirdly, G20 leaders for the first time listed the issue of development as a major topic, and the summit endorsed the Multi-year Action Plan on Development over the medium term, Ma said.
And fourthly, based on the achievements made in previous summits, G20 leaders pledged continuous efforts to intensify financial regulation and combat trade-protectionism, and put forward a series of new measures and steps which will be conducive to the long-term healthy and steady development of the world economy, he said.

Jaguar's supercomputing reign coming to an end?

A timeline of supercomputing speed.

The Jaguar supercomputer, housed at the Oak Ridge National Laboratory at the University of Tennessee, has been the fastest supercomputer on the planet for almost a year. But is it about to lose that title and place atop the podium?

Every six months, the Top500 project releases the rankings of the most powerful supercomputers. The current pace of technology development means the list does tend to reorder every half a year or so. But Jaguar has been poised at the top of the food chain for almost a year. Though the Top500 list doesn't get released until next week, it's been widely assumed that Jaguar will be taken down by a supercomputer built by China's National University of Defense Technology, located at the National Supercomputing Center in Tianjin.

Jaguar narrowly avoided being overtaken in June, the last time the rankings were released. The Nebulae supercomputer, located at the National Supercomputing Center in Shenzhen, came in second, achieving 1.271 petaflops/s (1.271 quadrillion floating point operations per second) running something called the Linpack benchmark.

But it appears that Jaguar's lead has been overcome this time. There have been reports about it over the last few weeks, and President Barack Obama even mentioned it during a speech last week:

"And we just learned that China now has the fastest supercomputer on Earth--that used to be us. They're making investments because they know those investments will pay off over the long term," he said.

The supercomputers are ranked on many factors, but the the Top500 list is ordered based on the results of the Linpack benchmark. Even if it places the Tianjin supercomputer above Jaguar, it doesn't necessarily mean the U.S. is getting bumped from its perch atop supercomputing, argue two scientists who work at Oak Ridge.


"What you find historically with these supercomputers is they become the normal machines 5 or 10 years later that everybody uses."
--Jeremy Smith, Center for Molecular Biophysics
"China might have the largest number of cores in one computer, so theoretically they have the most powerful computer. But they maybe don't have the most powerful scientific codes yet that use that computer," said Jeremy Smith, director of the Center for Molecular Biophysics at the University of Tennessee, in an interview. "So from that perspective, they may not be at the same level as Oak Ridge."

Jaguar is comprised of more than 250,000 AMD Opteron cores, running extremely sophisticated computer programs that try to answer complex questions like why ribosomes (components of cells that create amino acids) are dependent on magnesium, how to simulate making more environmentally-friendly ethanol out of plant material, and how to predict climate change. Jaguar's specialty is getting all those cores running together extremely efficiently, which is a separate and perhaps harder task than just building a really powerful computer.

Smith says that the projects at Oak Ridge National Laboratory run extremely efficiently on Jaguar, and the scientific value of the computing is therefore very high.

While China's supercomputer is based on GPUs (graphics processing unit) (in this case, built by Nvidia), and it's faster technically because the CPU (central processing unit) uses the GPU to accelerate its speed. But if you don't get the software to run on it properly, it's actually harder to use, Roland Schultz, graduate student at the University of Tennessee's Center for Molecular Biophysics, said.

What Schultz says he is much more interested in is the Gordon Bell Prize, which is awarded by the Association for Computing Machinery to the most innovative scientific application of supercomputing. Teams from Oak Ridge have won most recently in 2008 and 2009 for research into high-temperature superconductivity, or sending electricity over long distances in high temperatures with no loss of transmission.

But do we make too much of who's faster? Smith put it in perspective.

"What you find historically with these supercomputers is they become the normal machines 5 or 10 years later that everybody uses," said Smith. "The Jaguar machines that we're so amazed at right now, it could be every university or company has one" eventually.

We'll know exactly how things have shaken out next week when the Top500 List is released. But even if Jaguar does get hunted down by a Chinese supercomputer, it's not as if the folks at Oak Ridge are sitting still. The Department of Energy, which owns Oak Ridge's supercomputer, is already looking at moving from the current peta-scale computing (a quadrillion floating point operations per second) to exa-scale computing (a quintillion floating point operations per second), a speed one thousand times faster than Jaguar is currently capable of processing at.

"To get there in the next 5 to 10 years, to get to 10 million cores in one room, is a major technical challenge," noted Smith. "It's going to be fundamentally different than before. It's a hardware problem, and getting the software working is a major challenge indeed."

The article mentioned 250,000 cores of AMD Opteron. I am curious to know if those processors are the 4 cores or the new Barcelona 12 cores on 32 NANO. If they are the older 4 or 6 cores, they can be swaped out for the new 12 cores, because they use the same ZIFF socket. Just wondering....

Durr, who has the most cores and flops is meaningless now. Last I checked, Folding@home trumps the crap out of anything in China, and google's servers totally destroy any supercomputer, although they are not being used for that purpose. I understand the use of a single computer, but for many projects, it's just not needed.

This a good article that is very informative, however, the statement about ribsomes appears incorrect: ribosomes synthesize proteins from amino acids. Amino acids are not made by ribosomes.

When I first read this (on slashdot.org) I was concerned myself. However, I was directed to an interesting link about a supercomputer (US built) that will be ready in 2012: http://bits.blogs.nytimes.com/2009/02/03/ibms-sequoia-supercomputer-to-shatter-speed-records/ http://en.wikipedia.org/wiki/IBM_Sequoia I am sure you guys can find more articles if you are interested;nevertheless, I think we can rest easy if we are worried about speed records.

'Superb' Apple 1 on the block for £100k-£150K

1976 Jobs garage tech can be yours
Forgotten Tech An original Apple 1 made by Steve Jobs and Steve Wozniak in Jobs parent's garage goes on the auction block in London this month.

The Apple 1 was designed by Jobs and Steve Wozniak in 1976. Just 200 were made, according to the website Old Computers, and up to 50 are thought to survive.

At the time they cost £666.66, but Lot 65 is expected to fetch £100,000- £150,000, according to Christies, which says it is in superb condition.

Lot 65 has its original packaging, with the garage's return address on the typed label. Also included are the original manuals, a letter from Steve Jobs and an invoice dated 12/7/76.

Apple 1 - It could be yours

According to Christies, the Apple 1 was the first pre-assembled PC - no soldering required. As you can see from the picture above there was no casing, monitor, power supply, or keyboard. But in principle, it worked out of the box.

We have lifted the picture of an Apple 1 with lovely wooden casing from Wikimedia, so you can see what it looked like in anger.
