Project: CMS Grid
Description: The Compact Muon Solenoid (CMS, http://cmsinfo.cern.ch/) is a major experiment for the Large Hadron Collider (LHC) at CERN. The CMS detector is one of the largest international scientific collaborations in history. As of February 2003 there are 2300 people working for CMS, 1940 of which are scientists and engineers. These people come from 159 institutes in 36 countries, spanning Europe, Asia, the Americas and Australasia. Expected to come online in 2005, the detector will probe fundamental forces in our universe and search for the yet-undetected Higgs Boson. Computational and data challenges are substantial even during the current CMS design phase leading to LHC start-up in 2007. CMS will have 15,000,000 individual detector channels, all controlled by powerful computers that will synchronize the detector with the LHC accelerator to record significant collisions. Most often, protons will just graze each other rather than collide head-on, so events producing new particles will be extremely rare. Grid-enabled computing will help filter out inconsequential events, helping physicists to focus on the Higgs Boson that may appear in just one of every 1013 (10,000,000,000,000) collisions. CMS will accumulate data at a rate of about 100MB per second and petabytes per year. At 800 million collisions per second, it might appear only once per day, placing a high premium on the power and efficiency computational resources.
