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.
