The DataGrid Project
[link to eu-datagrid.web.cern.ch
"The Grid Physics Network, or GriPhoN, joins LIGO and the Sloan Digital Sky Survey with the Large Hadron Collider at CERN, the European accelerator laboratory. They form a computational and communications grid that ties together resources from the United States and Europe.
We expect that advances in developing petascale virtual data grids made in this project can be extended to other components of our nascent cyberinfrastructure.
Finally, we will see here how a networked system might bring data from all wavelengths and from ground and space-based telescopes to an international community of astronomers through a National Virtual Observatory.
Here we are watching the network at work - the integration of data from different wavelengths and from different telescopes, both in space and on the ground.
The virtual observatory will ultimately change the way science is done. For example, it will bring together the "separate wavelength cultures" and it will bring science to desktops around the globe.
These examples demonstrate that the demand for resources to archive, manipulate, and extract knowledge from databases is expanding at an accelerating rate."Computing: Getting us on the Path to Wisdom

"The LHC is being constructed at the CERN laboratory in Switzerland. The facility will consist of a superconducting particle accelerator providing two counter-rotating beams of protons, each with energies up to 7 TeV (7x1012 electron volts). ATLAS and CMS are being constructed to characterize the reaction products produced in the very high energy proton-proton collisions which will occur at intersection regions where the two beams collide. The LHC will enable a search for the Higgs particle, the discovery of which will be an important step in understanding the origin of mass of the known elementary particles, and will test the very successful Standard Model, which provides the existing framework for what is known about elementary particles and their interactions. The LHC will also enable a search for a new set of particles, predicted by a powerful theoretical framework known as supersymmetry, which will provide clues as to how the four known forces evolved from different aspects of the same "unified" force in the early universe.
The two LHC detectors will provide partially redundant and partially complementary information aimed at maximizing the chance of discovery. Both detectors will operate at extremely high data rates, which will push the state-of-the-art technology of electronic triggers, data acquisition, and data analysis. LHC experimenters in the U.S. are leading efforts to develop innovative "data grid" technologies that will allow them to analyze data from their own workstations as if they were at the LHC. Development of U.S. computational resources to fully exploit the opportunities that the LHC will present is currently being carried out with support provided through the Physics Subactivity within the Mathematics and Physical Sciences Activity."
