transfer data at world record pace
:: developing grid concept

Physicists recently set a world record for high-speed disk-to-disk transfer of research data. The rates achieved were equivalent to transferring all the data from a full-length DVD movie from one part of the world to another in less than 60 seconds, or a full compact disk in less than eight seconds. Within three hours, physicists successfully moved one terabyte of research data--equivalent to roughly 1,500 CDs from TRIUMF, the particle physics lab in Vancouver, to CERN, the international particle physics lab in Geneva.

"We are now coming to grips with the practical problems of establishing a world-wide computational grid to process the unprecedented amounts of data that will be generated by the ATLAS experiment when it begins to operate in 2007," said James Pinfold, who speaks for ATLAS Canada, the Canadian contingent of an international collaboration of 2,000 physicists. The ATLAS experiment will employ the world's highest-energy collider (the LHC) to explore the fundamental nature of matter and the basic forces which shape our universe. "The only way to deal with such unprecedented amounts of data is to utilize a new class of computing infrastructure--the GRID. The GRID is the World Wide Web of the 21st century," said Pinfold. The GRID will eventually link together computers, supercomputers and storage centers across the globe to create a world computer that makes it possible for the increasingly large and international modern scientific collaborations to share resources on a mammoth scale. This allows globally distributed groups to work together in ways that were previously impossible. The GRID "world computer" must have lightning fast and reliable communication of information between its nodes. >from *University of Alberta physicist helps transfer data at world record pace*, November 13, 2002
