Article: Computing Grid Helps Get to the Heart of Matter; A massive computing grid is helping physicists at CERN in Switzerland power the world's largest particle accelerator to answer the question: what other particles exist in the universe that we don't know about?

In November, when physicists at CERN in Switzerland begin their grand experiment using the world's largest particle accelerator-the Large Hadron Collider, or LHC-computer scientists there and across the globe will also put the world's largest scientific computing grid through its paces.

The success of the experiment-intended to answer such questions as what other particles exist in the universe that we don't know about-will rely in large part on a worldwide, high-speed network that will allow scientists to harness the power of 100,000 computers-mostly PCs-to process the tons of data generated by the experiment.

The universe consists of particles of matter, and scientists currently know ...
