GRID Computing^∗ — •Rüdiger Berlich — Lehrstuhl für Experimentalphysik 1, Ruhr-Universität Bochum, 44780 Bochum

The availability of high-performance network connections and the need to process and store huge amounts of data has led to a natural progression in the way the existing computer infrastructure is perceived and used. The requirements of the LHC experiments have led to a new paradigm in distributed computing, called No-dqthe GRIDNo-dq. The huge amounts of data produced by the upcoming LHC experiments cannot be processed entirely at CERN anymore. Instead, processing and storage capacities from participating institutions around the world are seemlessly bundled together, effectively creating a No-dqvirtual supercomputerNo-dq. Today, GRID computing is an important research topic beyond the boundaries of particle physics. Within Germany, GRID research is funded by the BMBF, European-wide projects like the European Data Grid are realised with the help of the European Union. The talk highlights the current developments in parallel and distributed computation with special emphasis on GRID computing. It gives examples from particle physics (BaBar) and explains the mission of the newly founded competence centre for GRID computing at the Forschungszentrum Karlsruhe, which will play an important role in the BaBar computing model.
