Fermilab Achieves Record in Grid Computing for Science|
Feynman Computing Center (Click on image for larger version.) (Photo: Peter Ginter)|
Today, in a milestone for scientific computing, researchers at Fermilab announced that the laboratory had sustained a continuous data flow averaging 50 megabytes per second (MB/s) for 25 days from CERN in Geneva, Switzerland to the tape storage facility at Fermilab. Fermilab and six other major global computing centers sustained a continuous data flow averaging 600 MB/s from CERN to tape and disk storage at locations around the world. The total amount of data transmitted in 10 days-500 terabytes-would take about 250 years to download using a typical 512 kilobit per second household broadband connection.
The achievements represented a successful exercise designed to test the global grid computing infrastructure that will be used by thousands of scientists worldwide working on experiments at the Large Hadron Collider, currently being built at CERN to study the fundamental properties of subatomic particles and forces.
"This service challenge is a key step on the way to managing the torrents of data anticipated from the LHC," said Jamie Shiers, coordinator of the service challenges at CERN. "When the LHC starts operating in 2007, it will be the most data-intensive physics instrument on the planet, producing more than 1500 MB/s of data continuously for over a decade."

SLAC restarts accelerator
By Will Oremus
The B-mesons are back in business.
The Stanford Linear Accelerator Centerís B-Factory experiment
which produces B-mesons to probe the mystery of how matter won out
over anti-matter in the moments following the Big Bang
is up and running again, five months after it was shut down due to safety

"Dark Energy" Dispute Heats Up
By Charles Seife
Is dark energy an illusion? Perhaps, says Edward Kolb, a physicist at the Fermi National Accelerator Laboratory in Batavia, Illinois. In mid-March, Kolb and three Italian collaborators posted a provocative paper arguing that dark energy--the mysterious antigravity force that makes the universe expand ever faster--is actually a byproduct of enormous ripples in the fabric of spacetime. Kolb's paper created ripples of its own, and now two theorists from Princeton University argue that Kolb's team made an accounting error that invalidates the result.
Let's Try Again: Plant A Tree for Earth Day Today|
Tree planting at one of the past Earth Days at Fermilab.|
Roads and Grounds will hold Fermilab's Earth Day tree-planting activities for employees and their families today (Monday, April 25). The event was rained out on Friday.
Please bring a shovel, and wear boots and gloves (and this year, bring your own lunch, too). The area to be planted this year is directly west of Warehouse II. Planting begins at 11:30 a.m., and make sure you read today's Safety Tip on protecting your hands. If there are any questions about the weather this morning, call Roads and Grounds at x3303.
And remember: Earth Day tree-planting and DASTOW are separate events for 2005, taking place on different dates. This year, DASTOW will take place on June 23, and more information about the day's schedule will be coming soon.
Given the amount of work we do with our hands every day, it's no
surprise they get hurt so often. Injuries can range from minor cuts
to amputations. A recent study found that metal items, such as nails,
metal stock, and burrs accounted for 38% of the injuries.
Hand tools with blades and powered machinery accounted for another 24%
and 12%, respectively.
A popular and effec-|
tive way to protect
your hands from many
hazards is with leather
Hand injuries can also occur from falls or material handling. In the
past quarter Fermilab had 22 work-related injuries, seven of which affected
the hand. The most severe of these resulted from a material handling incident
in which a worker moved a heavy egg-shaped glass table top by rolling it
on its edge. As it began to fall, he attempted to catch the top with his
left hand. The top struck his hand lacerating and fracturing the third
and fourth fingers. To save time, the worker chose to move the table
alone, in spite of a standing requirement to use two or more people.
To avoid hand injuries you should review the process before you begin
work. How could your hands get hurt? Make sure that machine guards
are in place. Use lock & tag procedures before un-jamming equipment.
If you need to put your hands where you can't see them, check for
hidden hazards with an inspection mirror. Consider wearing the
most protective gloves that are compatible with the process.
However, don't forget to balance glove use against the increased
added risk of entanglement (e.g., rotating tools).
Have a great day and let's work safely all week!
