SC|05 Bandwidth Challenge

By Les Cottrell

This year’s Bandwidth Challenge was held at the SuperComputing Conference (SC|05) that took place November 14-17 in Seattle. Scientists and their supercomputers demonstrated vast rivers of data traveling across the continents via our high performance networks.

The purpose of the challenge was to showcase high-impact data transfer among real applications. During SC|05 SLAC and Fermilab (in partnership with Caltech and others in Brazil, Japan, Korea, the United Kingdom and the U.S.) utilized more than twenty 10- gigabit-per-second light paths to transmit and display particle physics and astronomy data between the Labs and SC|05. The experiments include BABAR, CMS, CDF, D0 and SDSS.

In addition, the United Kingdom’s first dedicated optical network for research was put to the test by researchers from Manchester, London and Oxford with projects in astronomy, particle physics and molecular biology. The infrastructure, dubbed UKLight, is a high bandwidth optical network linked to similar networks around the world.

At last year’s Bandwidth Challenge SLAC partnered with Caltech, FermiLab, CERN, the University of Florida and groups from the United Kingdom, Brazil and Korea to defend its record. The team set a new world record for sustained bandwidth of 101 gigabit per-second—four times faster than our 23 Gbps record in 2003.
