An international team of physicists, computer scientists and network engineers has won the Supercomputing Bandwidth Challenge 2004 with a sustained data transfer of 101 Gbit/s between Pittsburgh and Los Angeles. This is equivalent to downloading three DVD-quality movies per second and more than four times faster than the previous record of 23.2 Gbit/s, which was set by the same team.

The Challenge allowed the scientists and engineers to preview the globally distributed Grid system that is being developed for the next generation of experiments at CERN's future Large Hadron Collider (LHC). To exploit fully the potential for discoveries, many petabytes of data will have to be processed, distributed and analysed. A hybrid network integrating both the traditional switching and routing of packets, and dynamically constructed optical paths to support the largest data flows, is central to the near-term future vision that the scientific community has adopted to meet the challenges of data-intensive science in many fields.

The team is led by the California Institute of Technology and includes Fermilab and CERN.
