“Want to read every single technical detail of the design and construction of the Large Hadron Collider and its six detectors? The whole shebang — seven reports totaling 1600 pages, 115 MB, with contributions from 8000 scientists and engineers — has been published electronically by the Journal of Instrumentation, free to read without a subscription.”

The end of the universe?

Friday, March 28th, 2008

“In what can only be considered a bizarre court case, a former nuclear safety officer and others are suing the U.S. Department of Energy, Fermilab, the National Science Foundation and CERN to stop the use of the LHC (Large Hadron Collider) until its safety is reassessed. The plaintiffs cite three possible ‘doomsday‘ scenarios which might occur if the LHC becomes operational: the creation of microscopic black holes which would grow and swallow matter, the creation of strangelets which, if they touch other matter, would convert that matter into strangelets or the creation of magnetic monopoles which could start a chain reaction and convert atoms to other forms of matter. CERN will hold a public open house meeting on April 6 with word having been spread to some researchers to be prepared to answer questions on microscopic black holes and strangelets if asked.”

A Detailed Profile of the Hadron Super Collider

Wednesday, May 16th, 2007

“The New York Times has up a lengthy profile of the Large Hadron Collider. The article covers the basics (size = 17 miles, cost = 8 billion, energy consumption = 14 trillon electron volts) and history but also provides interesting interviews of the scientists who work with the facility every day. The piece also goes into some detail on the expected experiments. ‘The physicists, wearing hardhats, kneepads and safety harnesses, are scrambling like Spiderman over this assembly, appropriately named Atlas, ducking under waterfalls of cables and tubes and crawling into hidden room-size cavities stuffed with electronics. They are getting ready to see the universe born again.’ There are photos, video and a nifty interactive graphic.

The World’s Fastest Image Processor

Thursday, February 9th, 2006

Roland Piquepaille writes “This image processor is not your typical digital camera. It took 6 years, 20 people, and $6 million to build the ‘Regional Calorimeter Trigger‘ (RCT) which will be a component of the Compact Muon Solenoid (CMS) experiment, one of the detectors on the Large Hadron Collider (LHC) in Geneva, Switzerland. The RCT will fill several racks of space in order to process 4 trillion bits of information per second while analyzing a billion proton collisions per second. The camera is currently being tested at the University of Wisconsin at Madison before being shipped to Geneva in June to participate in the first experiments in 2007.”

Harvesting and reusing idle compute cycles

Tuesday, July 5th, 2005

Excerpt from source: More on the University of Texas grid project’s mission to integrate numerous, diverse resources into a comprehensive campus cyber-infrastructure for research and education. In this article, the authors examine the idea of harvesting unused cycles from compute resources to provide this aggregate power for compute-intensive work. They will also place this concept in context by offering an overview of a popular commercial software package designed to help achieve this task: the United Devices Grid MP platform.

Several early grid computing projects were focused on the idea of harvesting unused cycles from compute resources and providing this aggregated computing power for work that comprised lots of tasks — from hundreds to millions — that could be executed individually.

Today, there are several commercial and open source grid computing software packages that support this form of distributed computing on the desktop or other nondedicated computing resources. In this article, we will take a look at a popular commercial software package designed to help execute this function: the United Devices Grid MP platform.

Grid MP has several interesting and unique features, including:

* Support for heterogeneous desktops/nodes
* Nonintrusive client execution
* Tolerance to failures of desktop resources

We will provide an overview of the Grid MP features designed for harvesting idle cycles from nondedicated resources, and we’ll describe the types of applications that can effectively use the type of “desktop grid” we’re discussing.
