China claims supercomputer crown, a threat?

China has claimed the top spot on the list of the world's supercomputers.
Tianhe supercomputer, Nvidia 
The Tianhe-1A supercomputer is about 50% faster than its closest rival.
 
The title has gone to China's Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.

To reach such high speeds the machine draws on more than 7,000 graphics processors and 14,000 Intel chips.

The claim to be the fastest machine on the planet has been ratified by the Top 500 Organisation which maintains a list of the most powerful machines.

High power
 
China's Tianhe-1A (Milky Way) has taken over the top spot from America's XT5 Jaguar at the Oak Ridge National Laboratory (ORNL) in Tennessee that can carry out only 1.75 petaflops per second. One petaflop is the equivalent of 1,000 trillion calculations per second.

The news about the machine broke just before the publication of the biennial Top 500 Supercomputer list which ranks the world's most powerful machines.

Prof Jack Dongarra from the University of Tennessee, one of the computer scientists who helps to compile the list, said China's claim was legitimate.

"This is all true," he told BBC News. "I was in China last week and talked with the designers, saw the system, and verified the results."

He added: "I would say it's 47% faster than the Oak Ridge National Laboratory's machine, 1.7 Pflops (ORNL system) to 2.5 Pflops (Chinese system)."

Tianhe-1A is unusual in that it unites thousands of Intel processors with thousands of graphics cards made by Nvidia.

The chips inside graphics cards are typically made up of small arithmetical units that can carry out simple sums very quickly. By contrast, Intel chips are typically used to carry out more complicated mathematical operations.

The machine houses its processors in more than 100 fridge-sized cabinets and together these weigh more than 155 tonnes.
Based in China's National Center for Supercomputing in the city of Tianjin, the computer has already started to do work for the local weather service and the National Offshore Oil Corporation.

Is China a supercomputer threat?

Jack Dongarra, a professor at University of Tennessee's department of electrical engineering. China's supercomputer is a 'wake-up call.'
 
With China expected to officially take the supercomputer performance crown next month, I asked an expert about the state of supercomputing in the U.S. and whether China poses a long-term threat to the United States' current preeminence in supercomputing.

Nvidia announced yesterday that its chips are powering the "Tianhe-1A" Chinese supercomputer that achieved 2.507 petaflops, beating a U.S.-based system that is currently ranked No. 1 on the June Top500 list of the fastest supercomputers in the world. The Chinese system is a unique hybrid design that uses approximately 7,000 Nvidia graphics chips along with 14,000 Intel Xeon CPUs. The graphics chips are what give the system the extra oomph to catapult it into the top supercomputer spot.

I spoke with Jack Dongarra, university distinguished professor at University of Tennessee's Department of Electrical Engineering and Computer Science and part of a group from the University of Tennessee, Oak Ridge National Laboratories, and Georgia Tech that recently purchased a hybrid system. It is important to note that Oak Ridge houses the supercomputer, dubbed "Jaguar," cited above that is currently ranked No. 1 in the world based on the Top500 June list: it is not a hybrid system.

Q: Does Oak Ridge have anything analogous to the Chinese hybrid system?
Dongarra: Oak Ridge has a small version of a machine that is hybrid in nature. So, this is an acquisition that just took place...out of a grant from the National Science Foundation. It involved Oak Ridge National Labs, University of Tennessee, and Georgia Tech. But it's much, much smaller than the Chinese system. The machine is in place and testing is being carried out at Oak Ridge. A node has two Intel Westmere chips and three Nvidia Fermi boards. There are 120 nodes in the system.

What makes the Chinese supercomputer so fast?
Dongarra: The Chinese designed their own interconnect. It's not commodity. It's based on chips, based on a router, based on a switch that they produce.

Is that in essence the secret sauce?
Dongarra: It's similar to Cray. Cray's contribution, besides the integration and software, is the interconnect network. They have a very fast interconnect that makes that machine perform very well. Though [the Chinese] project is based on U.S. processors, it uses a Chinese interconnect. That's the interesting part. They've put something together that is roughly twice the bandwidth of an InfiniBand interconnect [which is used widely in the U.S.]

Will the Chinese system in fact take the No. 1 spot on the Top500 list in November?
Dongarra: Yes. I saw the machine. I saw the output. It's the real thing.

Why doesn't Oak Ridge do what the Chinese are doing?
Dongarra: Oak Ridge doesn't have the ability or technology to develop an interconnect or a router. We don't make computers. We buy computers and use them. It's not within our scope or mission to be in the computer design business.

What's your advice?
Dongarra: You have to remember that you have to not only invest in the hardware. It's like a race car. In order to run the race car, you need a driver. You need to effectively use the machine. And we need to invest in various levels within the supercomputer ecology. The ecology is made up of the hardware, the operating system, the compiler, the applications, the numerical libraries, and so on. And you have to maintain an investment across that whole software stack in order to effectively use the hardware. And that's an aspect that sometimes we forget about. It's underfunded. We fund the hardware but we don't fund the other components. The ecosystem tends to get out of balance because the hardware tends to run far ahead of what we can develop in terms of software. We have machines that have a tremendous level of parallelism. We currently have a very crude way of doing programming.

Who would do that?
Dongarra: The research is performed under the auspices of the Department of Energy, the National Science Foundation, and the Department of Defense.

Is this a red flag for the U.S.?
Dongarra: Yes, this is a wake-up call. We need to realize that other countries are capable of doing this. We're losing an advantage.

Wall St reform architect Frank fights for survival



BOSTON (Reuters) - Representative Barney Frank, the outspoken, witty Democrat closely tied to the 2008 U.S. bank bailout, faces a tough re-election battle after 15 terms in office at a time when incumbency itself is a liability.

Challenging the Massachusetts liberal is Republican Sean Bielat, an Iraq war veteran, and opinion polls suggest Frank has an uncomfortably narrow lead over a political unknown.

In the run-up to Tuesday's congressional elections, Frank has faced a torrent of negative ads and mailings, much of it from groups outside the state who support candidates from the conservative Tea Party movement.

Last week, Frank borrowed $200,000 from his personal savings to prop up his campaign, saying he needed "to defend against outside attacks."

A recent opinion poll showed Frank with 49 percent of likely voters, Bielat at 37 percent and 12 percent undecided. Frank kept his seat in the House of Representatives with 68 percent of the vote in 2008 and ran unopposed in 2006.

Massachusetts has already been the scene of one of the year's biggest upsets, when Republican Scott Brown won a special election for the U.S. Senate seat held for almost five decades by a Democratic Party pillar, the late Edward Kennedy.

"If Barney Frank loses, it would be as significant as Scott Brown's win. You would really begin to see the depths of this anti-government sentiment," said Marc Landy, professor of political science at Boston College.

WALL STREET TIES THAT BIND

American voters are in a surly mood over the weak economy, unemployment near 10 percent and the state of the housing market as banks face scrutiny over how they handled the paperwork in home foreclosures across the country.

Frank, 70, has been chairman of the powerful House Financial Services Committee for almost four years.
He helped to broker the $700 billion fund to bail out banks at the height of the financial crisis and he promoted legislation to slow foreclosures and keep afloat Fannie Mae and Freddie Mac, the federally controlled companies that own or guarantee more than half of the $11 trillion in U.S. mortgages.

He was a chief architect of the 2010 Dodd-Frank Act, the Obama administration's plan for tighter regulation of the financial industry.

Bielat's campaign has tagged Frank as a "key player in America's financial collapse" who "has promoted much of what caused the worst economic downturn in decades."

Landy said some see Frank as the "personification of the cozy relationship between the government and irresponsible finance."

Frank's congressional district stretches from the affluent Boston suburbs of Brookline and Newton southward to the working-class towns of Fall River and New Bedford.

 The New Bedford Standard-Times newspaper has backed Frank over Bielat, 35, a political novice, former U.S. Marine and project manager at a company that designs and builds robots.

"Recoil from Barney Frank's gruff manner if you will, but his intellect and effectiveness make him invaluable," it said.

Even if Frank is re-elected, some wonder whether he might retire if Republicans gain control of the House, as most polls suggest, and he loses his committee chair
.
"Being in the minority is not as much fun," said Alan Wolfe, director of the Boisi Center for Religion and American Public Life at Boston College.

But Frank has unfinished business -- reform of Fannie Mae and Freddie Mac and defense of the Dodd-Frank Act against a Republican assault.

Some veteran lawmakers who lose powerful committee chairs might be tempted to call it a day, especially given the rancor in Washington, but Frank is probably not among them, said Thomas Whalen, a political historian at Boston University.

"He'll never quit," said Whalen. "He'll be taken out of the Capitol on a slab."

Survival-made-easyfor executives

By ANDREW LEE
andrewlee@thestar.com.my

How to Relax without Getting the Axe
Author: Stanley Bing
Publisher: Harper

FEW people working in large businesses seem content with their day-to-day jobs. The initial diligence that any newcomer displays is unsustainable as soon as he finds out that business is a hamster wheel, that he is the hamster running all day long, huffing and puffing to keep things turning.

As soon as it dawns upon the newcomer that there is in fact no future (or a bleak one, at the very least), work becomes a chore, effort is kept to a bare minimum, and quality of the final product is compromised. The newcomer eventually rises to a certain position where he no longer has the opportunity to advance any further, thus becoming the bitter and disgruntled employee who is stuck in a situation where staying on and quitting equate to the same thing – hardship.

Yet, for every obligated rodent who keeps the wheel running, there is a sleek furball happily “working” in the corner office down the hall. These guys seem to contribute less, and are often more unreliable and irresponsible. However, they soon rise to the top on the back of hefty bonuses and “business meetings” to various countries. The rodent, it seems, eventually mutates into the fat cat.

These crafty people have mastered the concept of executive life, what Bing describes as “the middle ground between slavery and unemployment”.

In his book, he goes on to explain the executive life. Citing examples such as the provision of big bucks with bonuses (in spite of screwing up), US$150 lunches, the loss of touch with reality, as well as drinks with “friends” who would like to see you dead. According to Bing, the secret of happiness is to live such a life whether one deserves to or not. The fact is that nobody deserves to. Therefore, to quote Bing: “Why shouldn’t you not deserve to at the same high level as other guys who don’t deserve to?”

The book teaches us a phalanx of ploys, evasions, hoaxes and clever swindles grouped together under a simple name: Executricks. Along the way, Bing guides us through the core skills that no budding office ear picker can afford to do without - delegation (telling people what to do and having them do it), absence (operating from the digital vacuum), abuse of status (it can be done), decisiveness (even when confused) and engagement (but only when necessary).

Bing cites a few examples of respected figures who have mastered executricks. The greatest delegator in history, Ronald Reagan was widely chastised back in the day for sleeping during meetings and allowing his wife to act as the actual chief executive. Yet, he is remembered as one of the greatest American presidents, with nary a word implying that he snoozed through the majority of his second term.

Today, great potentates such as Putin, Jobs, Gates and Kim Jong Il are honoured more in the breach than in the observance most of the time. They have mastered the ability to be the perceived train drivers when they are, in effect, invisible. Can you imagine a Kremlin worker complaining about how lame his boss is for not having been in the Pedestrian Control Department for years? No – the reason being that Putin is totally there, even when he’s not.

It may seem this is the perfect book for those who intend to shirk responsibilities, however Bing makes it clear in one of the final chapters in the book that work is inevitable to the executive. Work is like crisis; there is usually one waiting to happen. The goal therefore is clear – to work with maximum power for the shortest amount of time possible.

But how is one to know what work is, and what isn’t? Thankfully, included in the book are several important definitions of work:

a) Professional expertise, accumulated by you over a period of time, is needed;
b) The need to “get things right the first time” is not imaginary;
c) You get paid for it, and if you don’t do it you don’t get paid at all; and
d) Somebody told you to do it.

The key when the alarm bells sound are to treat every piece of work as a battle. There’s a reason why business types love to read biography and history – it provides them with a useful metaphor! There are numerous conflicts that one could be dealing with during work, and as long as one manages to avoid getting bogged down in long-term unwinnable campaigns (Vietnam, Iraq, Afghanistan), one should be fine. Transform these into short, hard pitched battles, and one can give up work and get back to “work”.

A word of caution. This book is not for budding yuppies looking to rise to the top of their respective businesses or management consultancies. There are various self-help, motivational and Warren Buffett-type books available in the market for such cases (although fetching tea or coffee while staying attentive to the various needs and wants of your boss probably helps as much, if not more). Rather, this book is for the person who realises his or her standing within an organisation, and intends to derive the maximum utility from such a position.

Bing’s ethics might be questionable – but then again, so were Machiavelli’s in the medieval period. And nobody called Sun Tzu a saint either, yet both men are exalted on the same podium as a certain Ronald Reagan. The same fate awaits Putin, Gates, Kim Jong Il and whoever else is able to master the subtle yet effective skills of executricks. Now if you will excuse me, there is a sandwich I need to enjoy.

NEW YORK (CNNMoney.com) -- All hail the puny dollar?

The greenback slipped once again Monday morning, falling to a new 15-year low against the yen. The dollar also fell against the euro and pound.
paul_lamonica_morning_buzz2.jpg
The renewed dollar sell-off comes after global financial ministers pledged to avoid currency wars at the conclusion of the G-20 meeting in South Korea Saturday.

Accusations of currency manipulation have roiled financial markets, with U.S. officials expressing frustration about how artificially low they believe the Chinese yuan is when compared to the dollar.

But global traders are continuing to sell the dollar. And that's because, somewhat ironically, many investors feel that the U.S. may be doing some manipulation of its own -- intentional or not.

The Federal Reserve is widely expected to unveil a new round of asset purchases at its next policy meeting, a two-day session that wraps up on November 3.

This so-called practice of quantitative easing is generally viewed as bad for the dollar because the Fed would be essentially printing money in order to pay for the long-term bonds it plans to buy.

Michael Pento, senior economist with Euro Pacific Capital in Westport, Conn., said that more quantitative easing is troubling because it may discourage foreign investors from buying the dollar, which is something they did in droves during the height of the financial crisis of 2008.

At that time, the dollar was still viewed as a safe bet and its status as the world's reserve currency was not in doubt. Pento worries that this may not be true for much longer.

"The dollar is being destroyed on a daily basis," he said. "Another massive round of easing would put everyone on notice that if you are seeking to hide in our dollar you will be severely punished."

The fear is that if the dollar continues to fall, foreign creditors will eventually get tired of the weak dollar and sell their Treasuries. That would push long-term yields much higher and could help bring about inflation.

So far though, as the chart at the top of this column shows, long-term yields have been edging lower even as the dollar continues to fall.

Along those lines, not everyone is sweating the weak dollar. Alex Bellefleur, financial economist with Brockhouse Cooper, a brokerage firm in Montreal, said it's worth noting that the stock market has been rallying as the dollar has weakened.

"The U.S. dollar has been the laggard in international currencies. But that could help in terms of boosting exports and earnings for large companies," Bellefleur said. "We don't think this is something that's negative in the near-term."

The problem is that at some point though, the cons to the weak dollar will outweigh the pros.

Pento said that if the widely-watched U.S. dollar index, which measures the dollar against a basket of key currencies, falls below 70, that could jeopardize the dollar's standing around the world. That index is currently around 77.

But Bellefleur doesn't think that the dollar will slide that much more. He said that for the dollar to truly lose its reserve status, something has to replace it. And he doesn't believe that will happen anytime soon.

"There are still no alternatives to the dollar as the world's reserve currency. The euro used to be viewed as possibly being one but people have had second thoughts about that," he said.

Dean Popplewell, chief currency strategist for Oanda, a Toronto-based foreign exchange broker, said investors should not forget gold. He noted that weakness in the dollar has coincided with the record run in the yellow metal.

So while investors may not think the euro can replace the dollar, gold -- which risk-averse investors love because of its tangible nature -- may be another story.

"At the moment, gold is trading as if it's the reserve currency. People want commodities over the dollar," Popplewell said.

Popplewell added that as long as the Fed has an easy money policy in place, the weak dollar trend is likely to continue. He predicts that the euro, currently trading around $1.40, could climb as high as $1.46 before the year is out.

"There will come a time when the dollar stops depreciating. But right now everyone has the same bet. It's a one-way, lemming trade," he said. "There is no money to be made on betting on the dollar at this point."

Blood pressure checks performed by barbers improve hypertension control in African-American men


Neighborhood barbers, by conducting a monitoring, education and physician-referral program, can help their African-American customers better control high blood pressure problems that pose special health risks for them, a new study from the Cedars-Sinai Heart Institute shows.
 
The study -- the first to subject increasingly popular barbershop-based health programs to a scientific scrutiny with randomized, controlled testing -- demonstrates the haircutters' heart health efforts work well enough that they could save hundreds of lives annually, according to results to be published online today on the website at http://archinte.ama-assn.org/ and in the peer-reviewed medical journal's Feb. 28, 2011, print issue.

In the research -- led by Ronald G. Victor, MD, a hypertension expert and associate director of the Cedars-Sinai Heart Institute -- barbers for 10 months offered blood pressure checks during men's haircuts and promoted physician follow-up with personalized health education for customers with high blood pressure. This enhanced screening program markedly improved blood pressure levels among the barbershops' patrons. Although blood pressure levels also fell in a comparison group whose members received only educational brochures about , the improvement was greater in the barber-assisted group.

Uncontrolled hypertension is one of the most prevalent causes of premature disability and death among African-Americans. African-American men have the highest death rate from hypertension of any race, ethnic and gender group in the United States – three times higher than white men.

"What we learned from this trial is that the benefits of intensive blood pressure screening are enhanced when barbers are empowered to become healthcare extenders to help combat this epidemic of the silent killer in their community"," said Victor, the Burns and Allen Chair in Cardiology Research. "Barbers, whose historical predecessors were barber-surgeons, are a unique work force of potential community health advocates because of their loyal clientele."

Since the 1980s, African-American-owned barbershops and hair salons have hosted screening programs for medical conditions that disproportionately affect African-Americans. Victor's study concludes that if hypertension intervention programs were put in place in the estimated 18,000 African-American barbershops in the U.S., it would result in the first year in about 800 fewer heart attacks, 550 fewer strokes and 900 fewer deaths.

Seventeen African-American-owned barbershops in Dallas and approximately 1,300 male patrons with confirmed hypertension participated in this study, which ran from March, 2006, to December, 2008, when Victor was professor of medicine at the University of Texas Southwestern Medical Center in Dallas.

All African-American men patronizing the participating shops were offered baseline blood pressure screenings for hypertension. The shops then were assigned randomly to the intervention or comparison group.

Barbers at the nine shops in the intervention group were trained to measure blood pressure properly and they offered free checks with every cut. If a customer's reading was high, the barber encouraged him to see his doctor, and, if he did not, the barber called the study's nursing staff to arrange a physician visit. The customer, in turn, got a free haircut if he returned to the shop with a doctor-signed referral card.

In the eight shops in the comparison group, customers received a blood pressure check at the study's outset, and then were offered standard educational pamphlets about hypertension.

At the study's conclusion, 20 percent more hypertensive patrons in the intervention group had their blood pressure controlled with medication compared to 10 percent in the control group.

"We need further exploration to make this kind of program scalable and sustainable," said Victor, who is launching a new study with African-American barbershops in Southern California. "If this kind of program could be applied to large numbers of African-American men, that would be an enormous asset in preventing heart attacks, strokes, kidney failure and other serious complications of hypertension,"

MPs Giving a Dressing Down to Teresa!

Teresa stands by her blouse

By LEE YUK PENG
yukpeng@thestar.com.my

PETALING JAYA: Seputeh MP Teresa Kok stood up to accusations that her long-sleeved blouse was “too revealing” for Parliament, saying she saw nothing wrong with her choice of outfit on Thursday.

The MP from DAP, who wore the blouse made of sheer material and a dress, was criticised during question time by Datuk Dr Marcus Mojigoh (BN–Putatan) who complained that her outfit was revealing (menjolok mata) and improper.

“It was long-sleeved and not entirely transparent. I see nothing wrong with the blouse. I will continue to wear it in future,’’ said Kok yesterday.

Dress issue: Kok showing the outfit she wore to Parliament on Thursday.
 
Kok, who was attacked 10 years ago in another episode involving her outfit, said the complaint was nonsense.

“I think Putatan (Dr Marcus) was seeking attention on TV since the first 30 minutes of question time is on live telecast,’’ she added.

Dr Marcus, citing Standing Orders, stood up to point out to Speaker Tan Sri Pandikar Amin Mulia that Kok’s outfit was revealing and inappropriate.

Pandikar Amin, however, defused the situation, saying he was not drawn to Kok’s clothes.

When contacted, Dr Marcus argued that Kok should be wearing formal attire like her male counterparts.

“I stood to remind her that she was not in proper parliamentarian attire. One must be serious in Parliament and not main-main (fool around). She wore a fancy dress as if she was taking part in a fashion show. Parliament is not the place for her to show how nice her dresses are,” he said.

Standing Order 41(f) states that a woman should either be wearing national attire, sarong or long-sleeved blouse with knee-length skirt, ceremonial dress or any attire permitted by the Chair in the Dewan Rakyat.

Giving MPs a dressing down must be done in private

I WAS bemused and at the same time irked by the news report in which Seputeh MP Teresa Kok (pic) was accused by Datuk Dr Marcus Mojigoh (BN-Putatan) of wearing a blouse that was “too revealing” for Parliament – and of all times, during Question Time.

Question Time in Parliament is an important session for MPs to discuss issues of national importance, not for trivial matters as an MP’s outfit.

Should it be true that any MP, regardless of whatever political party he or she belong to, has violated the dress code of Parliament, then he or she should be told in private by the Chair or Parliament officer in charge of protocol.

It is very unseemly for a person to criticise in public another person’s mode of dressing. In this case, more so because we are talking about national leaders who should know how to behave.

As a woman leader, Kok has it twice as hard as she is a minority in a very male-dominated field. It is difficult to retain your feminity when you are working with men.

If she were to dress a bit too feminine, she would be accused of “taking part in a fashion show”. And, if she were to dress more formally, she would be accused of trying too hard to be “one of the guys”.

As such, Marcus should have been more gracious when he found that her attire “menjolok mata” and behaved in a gentlemanly manner by going through the proper channels to advise her instead of shaming her in public, on national television no less.

Elected representatives should be more focused on doing their jobs.
