ARLINGTON - While there will be no collisions in the Large Hadron Collider near CERN in Switzerland until next year, on Friday computer centers worldwide celebrated the launch of the Worldwide LHC Computing Grid. The University of Texas at Arlington is a participant in this worldwide grid for LHC computing and physics professor Kaushik De is coordinator for the ATLAS grid in the United States.
Once LHC collisions begin, it is estimated that they will produce 15 petabytes (15 million gigabytes) of data annually. CERN alone cannot handle this data volume, so a worldwide distributed computing system has been created over the past decade to distribute the data almost in real time, and manage the use of the data by 7,000 scientists worldwide. The requirements for LHC computing have been driving many aspects of network, grid and distributed computing development for years, so the fact that this grid is up and running is a major achievement.
