Global computer circle ready for Big Hammer probe
By Frank Jordan, Associated Press
GENEVA While scientists fire up the greatest physics experiment in history this week they will deal with a task that makes getting a needle in a haystack look simple.
Inside a 17mile canal deep beneath the FrenchSwiss border they hope to identify evidence of extra dimensions, invisible "dark matter" and an incredibly elusive particle called the Higgs boson.
Success in this $10 billion effort would revolutionize each of our understanding of the universe,www.atmaskin.se/parajumpers.html.
SCIENCE FAIR: Banish those black opening fears: LHC is no security risk

But even the enormous computing power in the European Organization regarding Nuclear Research are unable to sift through all the data that will pour in when its particlesmashing try things out begins on Friday.
So the Genevabased lab, recognized by its aged French acronym CERN, devised a way of sharing the duty among dozens of leading computing centers around the globe.
The result is the "LHC Power grid," a global network of 60,1000 computers that will assess what happens when protons are hurled at each other within CERN's Large Hadron Collider.
"This is the next step following your Web," says David Colling, a researcher at Britain's Imperial Higher education, which is contributing to your Grid. "Except that in contrast to the Web, you're discussing computing power rather than files."
That computing power should be used if scientists will be to find what they are seeking among the mountains of knowledge produced when several giant detectors 10 times more accurate than just about any previous instruments start off measuring activity on the subatomic level.
"You can think about each experiment being a giant digital camera using around 150 trillion pixels taking shots 600 million occasions a second," describes CERN's Ian Bird, who leads the Grid venture.
Sophisticated filters discard all but the most exciting data, still making some 15 petabytes to be analyzed each year. That's enough to load two million DVDs.
The information are sent via highspeed lines to 14 top research institutions in Europe, America and Asia, as well as from there to a larger network of some 150 research services around the world where they can be scrutinized by thousands of researchers.
"The LHC experiment would not be possible without this infrastructure, that's why particle physicists get really driven the particular Grid," states Colling.
Building a new computer center at CERN could have been impractical and costly, so scientists proposed a distributed network that produces use of each country's own research services, ensures they all have equal access and gives them a chance to share in the particular glory of any breakthrough discovery.
Already the experience of participating on such a significant computing project features proved invaluable, says Ruth Pordes,Parajumpers jakker, executive director of the Open Science Power grid at Fermilab in Chi town.
"We are doing things that are at the boundaries of scientific disciplines," says Pordes. "But the technologies, the methods as well as the results will be picked up by industry.Inches
Scientists expect grid computing to become extensively used in future for research ranging from brand new drugs to more potent nuclear power. At some point, consumers will start discovering it used in daily life to regulated targeted traffic, predict the weather as well as boost a flagging economic climate.
"In credit risk, the amount of money you can lend out there is directly relative to how many computations you can do to evaluate your risk,Inch notes Imperial's David Colling.
Consequently even if the LHC experiment won't yield answers to the particular cosmic questions posed by physicists in CERN, historians may some day see it as a important step in the development of networked processing.
It wouldn't be the first-time that has happened in CERN. In 1990 a little daughter British researcher right now there created a computerbased system pertaining to sharing information together with colleagues around the world.
