Are You Ready for Petascale Computing?

When the world’s most powerful supercomputer goes online in 2011, it won’t come pre-installed with user-friendly software applications. Not to worry! To solve that problem, The Great Lakes Consortium for Petascale Computation will spend the next three years ramping up for the world’s first sustained petascale computational system by developing new computing software, applications and technologies designed for open scientific research.

The Great Lakes Consortium is the result of collaboration among colleges, universities, national research laboratories and other educational institutions dedicated to the Blue Waters Project.

The Blue Waters Project, based at the University of Illinois at Urbana-Champaign’s National Center for Supercomputing Applications, will build a machine in conjunction with IBM capable of sustaining computations of one to two petaflops – computing parlance for 1 quadrillion calculations per second – on many practical scientific and engineering applications.

The consortium’s ultimate goal is for Blue Waters to be fully user-friendly for scientists across the country, so when it launches, it will include intense support for application development, system software development, interactions with business and industry and educational programs.

Iowa State University researchers Srinivas Aluru, Mark Gordon and James Oliver say they’re eager to help the scientific community step into what they call the second revolution in information technology.

Aluru, a Stanley Chair in Interdisciplinary Engineering and a professor of electrical and computer engineering, will direct ISU’s work with the consortium.

“The dramatic increase in computing capability makes this project a national asset,” he said. “A lot of money will be poured into this research. To justify public expenditure we want to be ready.”

The National Science Foundation is supporting the supercomputer project with a $208 million grant, said Aluru, whose research group has used supercomputing power to help with the recently concluded effort to sequence the corn genome. To do that, they developed software that uses thousands of processors to build genome assemblies in days instead of months.

And now Aluru is ready to make the leap to even more powerful computing. But before that can happen, researchers must work out the bugs and bottlenecks that petascale computational levels might present.

The issue is not just Blue Waters’ peak potential, but its sustained capacity while solving problems, he said.

“That efficiency depends on the code we write,” he said. “We need to find the way to get higher than 70 percent efficiency on solving several challenges.”

Mark Gordon, ISU’s Frances M. Craig Distinguished Professor of chemistry and the director of the applied mathematics program for the U.S. Department of Energy’s Ames Laboratory, said parallel computing in chemistry, for example, has used, at most, clusters of 32-128 computers for supercomputing challenges for the past 15 to 20 years. Researchers therefore haven’t had the hands-on opportunity to work through the potential bottlenecks for using up to 100,000 clusters.

“It’s a whole new ballgame with new bottlenecks,” he said. “When you move toward the petascale range, we might run up against physical limitations, such as the speed of light. And the communications and data sharing issues increase by orders of magnitude. We’ll need an efficient way of communication and comparing and collecting.”

One of the consortium’s strategies will be forming petascale application collaboration teams or PACTS, Aluru said.

“Each team will work on individual problem to figure out how to use the petascale computer and avoid mistakes,” Aluru said.

Aluru said the Nation Science Foundation-funded project will provide two “step-up machines” along the way.

James Oliver, the director of ISU’s CyberInnovation Institute, said the jump to petascale computing power calls for tools such as C6, ISU’s six-sided virtual reality room that displays computer-generated images at the world’s highest resolution. He said C6 would be an ideal place to build interfaces that can display and work with all the data produced by the supercomputer.

Aluru said the consortium held its inaugural meeting this week to begin to lay out the technical challenges it faces. Back at ISU, Gordon said he’s waiting for word from the National Science Foundation to grant his team early access to the Blue Waters team and hardware.

“We’re looking forward to trying out our ideas to see if they’re going to work.”

Electromagnetic Drive

The Chinese are building a radical, game-changing propulsion technology. It converts electrical energy into thrust via microwaves. It will revolutionize satellites and space probes. It could get us to Mars in less than two months!

There’s just one little thing:

To say that the “Emdrive” (short for “electromagnetic drive”) concept is controversial would be an understatement. According to Roger Shawyer, the British scientist who developed the concept, the drive converts electrical energy into thrust via microwaves, without violating any laws of physics. Many researchers believe otherwise. An article about the Emdrive in New Scientist magazine drew a massive volley of criticism. Scientists not only argued that Shawyer’s work was blatantly impossible, and that his reasoning was flawed. They also said the article should never have been published.

Hmmm… The linked article goes on to say that the scientist who developed the idea stands by his work. So we’ll see. Looks like a pretty big longshot, though.

Panspermia Challenged

Well, at least that’s how the headline reads.

This was a cool experiment: they fastened rocks covered with both fossilized and living bacteria to the heat shield of a Russian space probe which re-entered the atmosphere. The results? The living bacteria got totally fried, but soe of the fossils came through.

So the experiment lends credence to the idea that this rock, which has been identified as coming from Mars really could have fossilized bacteria on it:

marsrock.jpg

But it would appear that these results deal a harsh blow to the theory of panspermia, the idea that life was carried to earth in the form of microbes hitching a ride on meteors. I would tend to argue that the experiment confirms that re-entry is a violent and traumatic process, and suggests that if panspermia did occur, those microbes were embedded pretty deep in the meteor that brought them. It would have needed to be more than two centimeters deep, per the results of the experiment.

That sounds pretty deep, but I’m guessing that there is bacteria on this planet embedded a lot more deeply in rock than that. In fact, they should split those rocks open and see if there isn’t something else living insided, something that was never intended to be part of the experiment.

Now that would be evidence for life traveling through space.

A New Ghostbusters?

FFR listeners know of my fondness for the first Ghostbusters movie. To me, it is the Godfather of comedy. For years fans have wanted a decent sequel. Finally, it looks like there’s some chance that it might happen.

Skip to the 5 minute mark:

Chrysler is Betting Big on EV / PHEV

Interestingly, they aren’t going with traditional Prius-like hybrids – where a gas engine directly pushes the drivetrain. Rather, they are going full EV for sports cars and Volt-like range-extension for everything else (where the electric engine always pushes the drive train and a small gas engine charges the batteries when necessary).

Chrysler plans on bringing these vehicles to market in two years.

Get this kid to MIT…

…fast!

12-year-old William Yuan has invented a new, improved 3D solar cell.

william yuan.JPG

William invented a novel solar panel that enables light absorption from visible to ultraviolet light. He designed carbon nanotubes to overcome the barriers of electron movement, doubling the light-electricity conversion efficiency. William also developed a model for solar towers and a computer program to simulate and optimize the tower parameters. His optimized design provides 500 times more light absorption than commercially-available solar cells and nine times more than the cutting-edge, three dimensional solar cell.

You know, this kid might just have kicked us over the Solar Singularity finish line. Grid parity has already been achieved in Hawaii – where there is plenty of sun and electricity is otherwise produced via diesel. But this development could bring solar to the rest of us.

More on 3D solar cells here.

Anything into
Oil

The smell is a mélange of midsummer corpse with fried-liver overtones
and a distinct fecal note. It comes from the worst stuff in the world—turkey
slaughterhouse waste. Rotting heads, gnarled feet, slimy intestines, and lungs
swollen with putrid gases have been trucked here from a local Butterball packager
and dumped into an 80-foot-long hopper with a sickening glorp. In about 20
minutes, the awful mess disappears into the workings of the thermal conversion
process plant in Carthage, Missouri.

Two hours later a much cleaner truck—an oil carrier—pulls up to
the other end of the plant, and the driver attaches a hose to the truck’s
intake valve. One hundred fifty barrels of fuel oil, worth $12,600 wholesale,
gush into the truck, headed for an oil company that will blend it with heavier
fossil-fuel oils to upgrade the stock. Three tanker trucks arrive here on
peak production days, loading up with 500 barrels of oil made from 270 tons
of turkey guts and 20 tons of pig fat. Most of what cannot be converted into
fuel oil becomes high-grade fertilizer; the rest is water clean enough to
discharge into a municipal wastewater system.

For Brian Appel—and, maybe, for an energy-hungry world—it’s a dream
come true, better than turning straw into gold. The thermal conversion process
can take material more plentiful and troublesome than straw—slaughterhouse
waste, municipal sewage, old tires, mixed plastics, virtually all the wretched
detritus of modern life—and make it something the world needs much more
than gold: high-quality oil.

The Good News:

An idea that addresses both our energy problems and our waste-disposal problems
at the same time has got to be a good one.

My expectation is that we won’t be terribly reliant on oil for energy a couple
or three decades from now; however, a process such as this might still prove
valuable even in a world where we don’t need oil to power our vehicles. For
one thing, aircraft will probably be slower to adopt alternative fueling strategies
than cars and trucks (which doesn’t mean that alternatives aren’t being
discussed
.)

In any case, I like a scenario that relies on human beings continuing to produce
waste. Sounds like a safe bet, doesn’t it?

Large
Hadron Collider "Actually Worked"

The world’s largest atom smasher’s first experiment went off today without
a hitch, paving the way toward the recreation of post-big bang conditions.

The Large Hadron Collider fired a beam of protons inside a circular, 17-mile
(27-kilometer) long tunnel underneath villages and cow pastures at the French-Swiss
border.

Inside the control room, physicists and engineers cautiously shot the beam
down part of the tunnel, stopping it before it went all the way around.

"Oh, we made it through!" one person cried as the beam made it
through a further section of the tunnel.

One hour after starting up, on the first attempt to send the beam circling
all the way around the tunnel, it completed the trip successfully—bringing
raucous applause.

The Good News

This is a banner day for science. The Large Hadron Collider will bring us to
new levels of understanding of the intricate workings of the universe.

Plus…

Hey, did you notice? The world didn’t end! We get so used to the world
not ending that sometimes we take it for granted. But in honor of our not being
sucked into a giant black hole or blasted back in time to when our entire universe
was nothing but diffuse particles, the Times
Online
has compiled a list of 30 other time the world didn’t end.

If you like that sort of list, keep this in mind: those thirty days are just
a tiny, tiny subset of the total number of days in which the world has not ended.
In fact, we are (and I hope I don’t jinx it or anything by pointing this out)
batting a perfect 1000 on that score.

Meanwhile, Stephen Hawking says that the
LHC is vital to our survival

Humans
Have Astonishing Memories, Study Finds

If human memory were truly digital, it would have just received an upgrade
from something like the capacity of a floppy disk to that of a flash drive.
A new study found the brain can remember a lot more than previously believed.

In a recent experiment, people who viewed pictures of thousands of objects
over five hours were able to remember astonishing details afterward about
most of the objects.

Though previous studies have never measured such astounding feats of memory,
it may be simply because no one really tried.

In the experiment, 14 people ranging from age 18 to 40 viewed nearly 3,000
images, one at a time, for three seconds each. Afterwards, they were shown
pairs of images and asked to select the exact image they had seen earlier.

The test pairs fell into three categories: two completely different objects,
an object and a different example of the same type of object (such as two
different remote controls), and an object along with a slightly altered version
of the same object (such as a cup full and another cup half-full).

Stunningly, participants on average chose the correct image 92 percent, 88
percent and 87 percent of the time, in each of the three pairing categories
respectively. Though 14 subjects may not sound like a huge sample, the fact
that they each recalled the objects with very similar rates of success suggests
the results are not a fluke.

The good news…

What intrigues me most about this story is that it was a test that had simply
never been tried before. We still have a lot to learn about what human beings
truly are capable of doing, and we may well be surprised — again and again
— to learn that we can do more than we thought we could.

Lost cat returned home after nine years

LONDON (Reuters) – A couple have been reunited with their missing cat after
nine years, the RSPCA said Wednesday.

Dixie, a 15-year-old ginger cat, disappeared in 1999 and her owners thought
she had been killed by a car.

She was found less than half a mile from her home in Birmingham after a concerned
resident rang the animal charity to report a thin and disheveled cat who had
been in the area for a couple of months.

RSPCA Animal Collection Officer Alan Pittaway checked her microchip and confirmed
it was Dixie. She was returned to her owners, Alan and Gilly Delaney, within
half an hour.

The Good News:

Dixie has to get a lot of credit in this story for managing to stay alive as
long as she did and for presumably finding her way back to the old ‘hood. True,
she might have been there all along, but it seems likely in that case that she
would have found her own way home at some point over those nine years.

But the real hero of this story has got to be the microchip. Turned over to
the RSPCA, what are the chances that an un-chipped Dixie would have ever traversed
that final half mile?

Anyway, if you want even more pet-related good news, check out this headline:

Where
Sweat Equals Electricity

It sounds like something you’d only see on the Discovery Channel: people
pedaling ferociously to create enough energy to power the television, stereo
and lights.

Launched last week, his "human-powered" gym is one of few fitness
centers in the world that runs on power generated by people working out, Boesel
said.

As members pedal on stationary bicycles, a small motor connected to the stations
charges batteries that power the gym’s television and stereo system.

Boesel said he doesn’t yet have a way to quantify the output but knows that
at the moment it’s relatively small. However, this is just the beginning,
he said.

"Our goal is to someday create 100 percent of the electricity we use
in the gym," Boesel said. "The short-term goal is to get all of
the electricity we can out of the machines."

The good news:

What a great business model — requiring your gym patrons to pay you for the
privilege of generating the electricity you need to run your gym. Of course,
it sounds like Boesel has a long way to go before this activity is really "running"
his gym. He needs to get some elliptical and stair-climbing machines into the
mix.

Also, this raises an interesting hypothetical: what kind of physical condition
would we all be in if we were required to generate, through our own activity,
say 5% (or even 1%) of the total electricity we use?

Nerve
Surgery Leaves Woman With Feeling in an Arm That Isn’t There

Claudia Mitchell may look like your average 20-something college student.
She is anything but.

As a result of an experimental surgery, Mitchell has become the first real
"Bionic Woman": part human, part computer.

The "targeted reinnervation" surgery was developed by Dr. Todd
Kuiken of the Rehabilitation Institute of Chicago. It was a radical idea:
a robotic arm controlled not by a patient’s stump or shoulder, but by a patient’s
thoughts.

Mitchell, a U.S. Marine, was ready to try anything to have a second functioning
arm. She volunteered for the surgery.

During the six-hour procedure in 2006, doctors took the severed and dormant
nerves in Mitchell’s shoulder, nerves that are used to control the movement
of her arm, and put them under the muscle in her chest.

They wanted the nerves to reawaken and work her chest muscle. The doctors
eventually used the electrical nerve signals from that chest muscle to power
a new bionic arm.

The good news:

The linked article goes on to tell how Mitchell is learning to operate her
arm via her rewired nerves. She can now perform everyday tasks such as folding
clothes and chopping vegetables. And, in a development that only deepens the
mystery of how the human nervous system works — but promises to help us understand
it better one day — sensation has returned to Mitchell’s "hand."
That is, she can feel temperature, pressure, and other sensations in a hand
that is no longer there, or — if you prefer — in a mechanical hand that can’t
possibly experience such feelings.

We’ve all heard of the amputees who feel a twitch or an ache in a long-absent
limb. Maybe we should no longer view the ability to experience such sensations
as some kind of sensory mistake, but rather as evidence of the robustness of
the human nervous system. Of course, there is plenty of evidence of that robustness
to be found in this young woman’s ability to move her robotic arm via thought
— essentially the same way she moves her biological arm. This story offers
tremendous hope not only to amputees but to victims of paralysis who hope one
day to experience the basic sensation of touch.

In a related development, scientists are developing a working bionic
eye
which they say will be ready in five years or so. We may not yet understand
the human body, but our ability to replicate its functionality is growing

Daydream achiever

ON A SUNDAY morning in 1974, Arthur Fry sat in the front pews of a Presbyterian
church in north St. Paul, Minn. An engineer at 3M, Fry was also a singer in
the church choir. He had gotten into the habit of inserting little scraps
of paper into his choir book, so that he could quickly find the right hymns
during the service. The problem, however, was that the papers would often
fall out, causing Fry to lose his place.

But then, while listening to the Sunday sermon, Fry started to daydream. Instead
of focusing on the pastor’s words, he began to mull over his bookmark problem.
"It was during the sermon," Fry remembers, "that I first thought,
‘What I really need is a little bookmark that will stick to the paper but
will not tear the paper when I remove it.’ " That errant thought – the
byproduct of a wandering mind – would later become the yellow Post-it note,
one of the most successful office products of all time.

Many scientists argue that daydreaming is a crucial tool for creativity, a
thought process that allows the brain to make new associations and connections.
Instead of focusing on our immediate surroundings – such as the message of
a church sermon – the daydreaming mind is free to engage in abstract thought
and imaginative ramblings. As a result, we’re able to imagine things that
don’t actually exist, like sticky yellow bookmarks.

The good news:

On the most recent FastForward
Radio
, we talked about a meme that we think is well worth spreading: the
notion that creativity
is as important as literacy
in dealing with our multi-faceted, rapidly changing
world. Daydreams, it would seem, are one of the best tools we have to develop
creativity. The research shows that there are two kinds of daydreams, the ones
that you fall into without realizing it and the ones you enter more or less
as a conscious choice. It’s this latter kind that promotes creativity.

So let’s start building a better future, people. Let’s get going
on some intentional, deliberate daydreaming.

Long-life gene that triples chance of living to 100 found

Men who have two copies of a "long life gene" triple their odds
of living nearly a century, according to a study published today.

The advantage is all down to having two "letters" of the six billion
letter human genetic code that are the same and the scientists who report
the find believe that this kind of understanding could have important implications
for living longer and lowering the risk for age-related disease and disability.

The gene linked with better health and a longer life is called FOXO3A and
although similar genes have been shown to prolong life span in other species,
this is the first time that FOXO has been linked directly to longevity in
humans.

The Good News:

The genetic "cure" for aging has a lot of promise for later generations
of humanity. Once we get comfortable with sequencing heart disease, diabetes,
and breast cancer out of our offspring’s genetic code, nothing will be more
natural than wanting to protect them from the suffering that aging brings about.

We’re still a step or two away from gene therapies that could help people who
are already born avoid aging. But this is certainly an encouraging step in that
direction.

Massive floating generators, or ‘eco-rigs’, to provide power and food to Japan

Battered by soaring energy costs and aghast at dwindling fish stocks, Japanese
scientists think they have found the answer: filling the seas with giant “eco-rigs”
as powerful as nuclear power stations.

The project, which could result in village-sized platforms peppering the
Japanese coastline within a decade, reflects a growing panic in the country
over how it will meet its future resource needs.

The floating eco-rig generators which measure 1.2 miles by 0.5 miles (2km
by 800m) are intended to harness the energy of the Sun and wind. They are
each expected to produce about 300 megawatt hours of power.

The Good News:

These rigs will not just supply much-needed power to the Japanese mainland,
they will be nurseries for coral and plankton, and may ultimately help to
rebuild Japanese fisheries. Plus, I think there’s a fair chance that these
rigs — once implemented — would become interesting communities. Bigger than
a ship, smaller than an island. Tourism might ultimately become a side business.
I know I wouldn’t mind spending some time on one.

Better All The Time was compiled by Phil Bowermaster. Live to see it!

This seems like a big deal…

Computers figuring out what words mean

It’s probably more accurate to say that computers are being taught what words mean.

The first use of this technology will be to improve web searches. Since the computer understands the meaning behind words, it will be more successful finding what you really want than it is currently by just matching words.

We have taught the computer virtually all the meanings of words and phrases in the English language,” Cognition chief executive Scott Jarus told AFP.

“This is clearly a building block for Web 3.0, or what is known as the Semantic Web. It has taken 30 years; it is a labor of love,” Jarus said.

The semantic map is reportedly the world’s largest, and gives computers a vocabulary more than 10 times as extensive as that of a typical US college graduate.

The coming third generation of life online is predicted to feature intuitive artificial intelligence applications that work swiftly across broadband Internet connections.

When applied to Internet searches, semantic technology delivers results oriented to what people seem to be seeking instead of simply matching words used to online content.

For example, a semantic online search for “melancholy songs with birds” would know to link sadness in lyrics with various species of birds.

Cognition says it has also “semantically enabled” globally popular online encyclopedia Wikipedia.

Phil asked “AI or IA?” This seems to be evidence that we are close to AI.
