New top supercomputers list

It's that time of year again. In June and in November the supercomputing world submits its scores to see who has outFLOPped whom.

The new list at shows that Roadrunner remains on top, but only because it's had some upgrades in the last 6 months. The good folks at top500 say Roadrunner (which is among the most energy efficient because of its Cell processors) narrowly fended off a newcomer, Oak Ridge National Lab's Jaguar, which became only the second machine to top a petaflop.

1 DOE/NNSA/LANL Roadrunner

2 Oak Ridge National Laboratory Jaguar XT-5

3 NASA/Ames Research Center/NAS Pleiades


5 Argonne National Laboratory Blue Gene/P

6 Texas Advanced Computing Center/Univ. of Texas Ranger

7 NERSC/LBNL Franklin

8 Oak Ridge National Laboratory Jaguar XT-4

9 NNSA/Sandia National Laboratories Red Storm

10 Shanghai Supercomputer Center Dawning 5000A

The geography of supercomputing has gotten pretty skewed of late in favor of the United States. The New York Times did a nice infographic showing the location of the top 50. Of the new top 10 only number 10, Shanghai-based Dawning 5000A, is outside the United States. From the entire list of 500, 290 are in the United States. My personal favorite this year, India's EKA, was ejected from the top 10 back in June.

Nanotech Medicine: Yes...Nanotech Enhanced Humans: No

It seems that one of the largest areas of research in nanotech is becoming surveys. See here, here, or here.

In keeping with this general research trend, North Carolina State University in cooperation with Arizona State University have released their findings on what the public sees as the correct directions for nanotech.

Apparently, nearly 90% of respondents support medical breakthroughs enabled by nanotechnology, while only 30% are in favor of human enhancement brought about by nanotechnology. At least thatâ''s how the results are parsed here.

I am not sure if the researchers are again indulging in that fun parlor game of demonstrating how ill-informed US respondents are on the subject of nanotechnology, or what. But apparently the division between medical breakthroughs and human enhancement doesnâ''t really exist except in the prejudices of the respondents.

The example given that nearly 90% of people supported would be a â''video-to-brain link that would amount to artificial eyesight for the blindâ''. On the other hand, the example for which only 30% of respondents supported was â''implants that could improve performance of soldiers on the battlefield.â''

Just to clarify, both examples concern human enhancement. Except one is for military use and the other one is for the blind.

I guess if someone called me up and asked if I were pro or con on the subject of euthanasia for cuddly little puppy dogs, or rabid, baby killing pit bulls, my response would say less about my position on euthanasia and more about how I preferred puppies to rabid dogs.

Shuttle and Space Station Crews Work on Expansion Scheme

The International Space Station (ISS) is expanding again.

The shuttle Endeavour has arrived at the space station with a payload that will increase the floor space of the orbiting platform to make it possible for it to house six space travelers in the future. The main task of the current shuttle mission, STS-126, is to attach the Italian-made Leonardo Multi-Purpose Logistics Module (MPLM) filled with "goodies" to the tip of the ISS. NASA said in an online statement today that the Leonardo cargo container has been successfully attached to the nadir port of the Harmony Node, the "utility hub" of the ISS.

NASA has packed the Leonardo MPLM with systems to be installed in the Harmony Node and Destiny Lab, including: two water recovery systems racks for recycling urine into potable water, a second toilet system, new galley components, two new food warmers, a food refrigerator, an experiment freezer, a combustion science experiment rack, two separate sleeping quarters and a resistance exercise device.

"We're here to work," Endeavour Commander Mike Fincke reported to mission contol. "This is the can-do crew."

Fincke called the cargo in the Leonardo MPLM "the goodies ... things needed for an extreme home makeover."

Bad News Bearish

â''2001â'' is shaping up to be the new cliche, as business reporters compare the current state of tech stocks to the post-Bubble panic. Every day seems to bring a new headline about some tech stock plunging to previously-unseen depths.

â''Things have gotten worse every week of October and even worse in November,â'' Charter Equity Research analyst John Dryden told the New York Times.

â''People donâ''t have any money left to buy cool gadgets,â'' another research analyst said in the same article.

So here it is, your bad news roundup (after the jump). Iâ''ve tried to include good news where possible.

Bad NewsGood Newsthe Numbers
IntelSales could fall as much as 19 percent in the fourth quarter.It's Intel. They'll be all right.Expected fourth-quarter revenue of $8.7 billion to $9.3 billion, down from the earlier projection of $10.1 billion to $10.9 billion.
AMDPlans to lay off 500 people, or around three percent of its work force.AMD bought itself a little bit of breathing room with its Shanghai quad-core Opteron processors.AMD reported a net loss of $67 million, or 11 cents a share, in the third quarter, compared with a loss of $396 million, or 71 cents a share, in the year-ago quarter.
Cadence On October 16, its chief executive and four other senior executives took offâ''"an unusually sweeping shake-up."Not much.Cadence shares plunged about 15%, or 80 cents a share, to $4.80 on the Nasdaq. A month later, they're hovering around $3.91. Cadence's projection of a third-quarter loss is due to industry-wide issues that include weaker demand for the software to make chips.
SunPlans to lay off 5,000 or 6,000 workers, more than 15 percent of its global workforce, over the next year.Not much.Stock price has plummeted, closing at $4.08 on Thursday, down from a 52-week high of $21.55. And last month, Sun reported a $1.67 billion loss in its most recent quarterâ''mostly due to a $1.45 billion charge to write down the value of past acquisitions.
Plans to cut 1,800 jobs, close to 12 percent of its workforce.Not much.45 percent drop in fourth-quarter profit to $231 million, down from $422 million last year. Sales tumbled 14 percent, to $2.04 billion from $2.37 billion last year.
Nvidia74 per cent drop in profit for its third quarter of 2008. Being sued by Rambus (but then again, who isn't?); losing market share to ATi due to poor VGA card pricing and lower than expected performance; the famous notebook video card recallâ'¿

Even this was better than what Wall Street was expecting.Net profit of $61.7 million, or 11 cents a share, in the three-month period. Last year it made $235.7 million, or 38 cents a share, in the comparable period.
HPIn September, the company said it will lay off 24,600 people over the next three years, or nearly 8 percent of its workers.The memistor? HP was down more than 7% on Wednesday, bringing it to HP's stock down more than 40 percent this year.
Dell chief technology officer Kevin Kettler plans to step down soon; in August, the company said it had cut 8,500 jobs. Countless variations on "Dude, youâ''re not getting a Dell."Dell shares fell as much as 15 percent on Wednesday; for 2008, Dell shares are off more than 60 percent.

Nuclear arms control talks start: there's a role for reliability engineering

The United States and Russia are scheduled to hold talks in Geneva starting today and lasting until 21 November to craft a new nuclear weapons treaty. The Strategic Arms Reduction Treaty (Start) was signed in Moscow in 1991 and expires in December 2009. There's much haggling over what should replace it, with complications coming from a U.S.-European missile shield. It would do for both sides to consider the real risks of nuclear war involved.

Earlier this year, Martin Hellman, the co-inventor of public key cryptography, tried just that. He applied reliability engineering methods to figure the rate of failure for nuclear deterrence. Though it's not the only possible trigger of a nuclear confrontation, Hellman focused on a "Cuban Missile Type Crisis" as the cause. See our story last April for Hellman's fascinatng equation for armageddon, but I've pasted the rather disturbing results here:

The result is a range from 2 chances in 10 000 per year to 5 chances in 1000 per year for just this one type of trigger mechanism. The values are valid only for the Cold War years, writes Hellman. But that doesnâ''t make them irrelevant at a time when relations between the United States and Russia are deteriorating; India and an unstable Pakistan have acquired atomic weaponry; and military planners from Washington, Tokyo, and Seoul worry about whether a nuclear-armed China would go to war to reclaim Taiwan.

Hellman's careful to say that he's not necessarily advocating complete disarmament. After all there is probably risk to not having a nuclear deterrent, too. Instead, like a true academic, he just wants somebody, such as the National Academy of Engineering, to do a far more nuanced analysis than his own; so that policy makers and the public have a real understanding of what the risks of nuclear strategies really are. Check out his website devoted to the cause here.

Round-Up of Coverage on Royal Commissionâ¿¿s Nanomaterials Report

Both the mainstream press and nanotechnology-related blogs have been furiously covering the recent report from the UKâ''s Royal Commission on Environmental Pollution on the potential risks of new nanomaterials.

In my previous post, I alluded to some of these. But it might be worth providing a brief round-up of both the news coverage and editorial comment.


Richard Jonesâ'' Soft Machines Blog covers it here.

Andrew Maynardâ''s 2020 Science Blog covers it here.

Cientificaâ''s TNTLog covers it here.

For the mainstream press, I have limited the list somewhat just to reflect the differing tones given to the story:


Financial Times

The Daily Mail

The coverage of this story still seems to be centered around the UK press. We'll keep an eye on the story to see how international it becomes.

Researchers Use Hubble to Detect New Giant Planet

Chalk up another breakthrough for the Hubble Space Telescope.

The orbiting science platform has detected a gaseous exoplanet three times the mass of Jupiter 25 light-years away near a star in the constellation Piscis Australis. Astronomers trained the Hubble's Advanced Camera for Surveys on the star Fomalhaut in 2004 to capture visible-light images of protoplanetary debris approximately 21.5 billion miles across and having a sharp inner edge, according to a statement from NASA today.

A NASA team led by Paul Kalas, of the University of California at Berkeley, proposed in 2005 that the debris ring was being affected by a large planet near it. Newer data sent from Hubble in 2006 has been under study by the Kalas team for the last two years and has now been released, published in an article in the journal Science. Their research concludes that an exoplanet, dubbed Fomalhaut b, about 119 astronomical units from the star is responsible for the gravitational influence around it.

The above image (courtesy NASA) is an artist's rendering of a planet orbiting the star Fomalhaut.

"Fomalhaut is the gift that keeps on giving," said team member Mark Clampin of NASA's Goddard Space Flight Center, in Greenbelt, Md. "Following the unexpected discovery of its dust ring, we have now found an exoplanet at a location suggested by analysis of the dust ring's shape. The lesson for exoplanet hunters is 'follow the dust'."

NASA said future observations by Hubble's (newly revived) cameras will attempt to see the planet in infrared light and will look for evidence of water vapor clouds in the atmosphere of Fomalhaut b.

(Micro)Power to the People Featured at 2008 Tech Awards

Last night San Joseâ''s Tech Museum of Innovation presented its annual Tech Awards, honoring technology benefiting humanity. The 25 finalists, drawn from 650 nominations from 68 countries, had developed devices and programs to address issues in healthcare, the environment, and education, as well as more general needs of developing nations. Some innovations use relatively simple technology to turn local waste or weeds into building materials or fuel; some rely on advanced technology, like flexible solar cells made from nanomaterials or three-dimensional computer displays.

Before the three winners were announced, I had a chance to chat with some of the honoreesâ''the Tech Museum calls them laureatesâ''about their projects. Many involved power and energy in one form or another, either saving energy, like NComputing, a company that enables large groups of users to simultaneously use one computer, with dramatic power savings. Or generating energy from novel fuels, like VWP, a German company designing tractor engines optimized for running on pure plant oil, and the Cheetah Conservation Fund, which has developed a process for converting an invasive plant that had been destroying the cheetahsâ'' savannah habitats into a clean-burning fuel log.

IMG_2493.JPGWhat struck me most, however, was the way that many of these entrepreneurs are redefining the problem of power generation and distribution in the developing world. Hari Sharan [photo, left], chair of D.E.S.I Power, based in Bangalore, India, told me, â''The centralized system of power distribution has failed the villages.â'' The problem, he explained, is that bringing power from a central generating facility out to small villages just doesnâ''t make economic sense, because there are no customers in the village.

So D.E.S.I, while it does build power generating facilities, using biomass gasification, does not expect to survive by simply offering power for sale. Instead, it expects that around each generation station a host of small businesses will emerge, selling what power creates.

â''Light,â'' for example, says Sharan. â''A local entrepreneur could collect portable lights from 50 households, bring them in for recharging, and then deliver them back.â''

D.E.S.I has five units running in villages so far, and is on track to have 100 built within the next three to four years.

IMG_2495.JPGSunlabob, based in Laos, another Tech Awards Laureate, is also bringing power to the people. Like D.E.S.I., it relies on what, in the computer world, would be called a â''Sneakernet,â'' that is, power is moved by being walked from place to place, instead of sent over a wired network. Sunlabobâ''s solar-powered charging stations charge individual battery-operated lamps; a local entrepreneur then rents these lamps to households, charging for the amount of hours of light used. Sunlabob CEO Andy Schroeter [photo, right] says at about 30 cents for 10 hours of light, the cost is much lower than kerosene, which is what many households in the developing world use for light today. Sunlabob has some 2500 stations installed in Laos, and is expanding in Cambodia, Tanzania, and Afghanistan.

IMG_2488.JPGIn the Sierra Madre area of Mexico, light is also an essential and hard-to-obtain resource, says Frano Violich. The Huichol people rely on the handicrafts they make, mostly textile art and beadwork, for income. A good light can give them a few valuable extra hours a day to work. It can also improve educational opportunities; children typically travel long distances for school, by the time they get home it is usually too dark to study, Violich says. The Portable Light Project, started by Violich and Sheila Kennedy, is providing kits containing flexible solar panels, cell phone batteries, and LEDs that local craftspeople can integrate into the traditional woven bags [photo, left] both men and women carry constantly (for Huichol clothing does not have pockets). They also provide patterns so craftspeople can create reflective housings to magnify the light from the LED.

The winners of $50,000 cash prizes, one in each of five categories (environment, economic development, education, equality, and health), were the Cheetah Conservation Fund, D.E.S.I. Power, the Digital Study Hall, Build Change, and Star Syringe. The awards are sponsored by Applied Materials, Intel, Accenture, Microsoft, Santa Clara University, The Swanson Foundation, and the Fogarty Institute for Innovation.

Obama's Open Source CTO


Yesterday, the Obama people created a new site called, a feedback forum that opens the floor to suggestions: What should be the CTO's top priorities?

I hope Spectrum readers are well-represented here.

I'm already excited about the Obama administration just for the way he's doing business as president-elect. He could do worse than trying to harness the wisdom of crowds. Regardless of who you voted for, you'll agree that a White House CTO will be a heck of a lot more useful than a Drug Czar.

Hysteria versus Reason in Assessing Nanotechnology Risk

The UK approach to examining and assessing the risk of nanomaterials seems to come from two polar opposites: overheated hysteria and chilly rationality.

In one corner, you have the British tabloid press ratcheting up the fear factor with Armageddon-like headlines like the one highlighted over at TNTLog that reads: â''Tiny but toxic: Nanoparticles with asbestos-like properties found in everyday goodsâ''.

In the other, you have venerable institutions like the Royal Society and Royal Academy of Engineering trying to bring reasoned and researched recommendations to the powers that be.

Unfortunately, the UK is not alone in this approach as it represents more or less how the rest of the world seems to be addressing the matter. First, there is quiet, reasoned research that suggests government look at the associated risks of nanomaterials and how they might be ameliorated. Then the government ignores the recommendations since it canâ''t be bothered by anything that isnâ''t shouted at them by a mob. Finally, sooner or later, the mob begins shouting.

This little scenario is being played out right now in the UK, and it should serve as a lesson to us all. If governments ignore the scientists in shaping their regulations and guidelines, they will likely end up being forced to heed the screaming mob. The result will be far inferior regulations that will likely be unable to balance the need for public safety with needed innovation.
