SuperComputing 2009
Moving Towards Terabit/Sec Transfers


 Press Release

The SuperComputing Conference 2009 was held in Portland, Oregon(USA) this year. An international team of physicists, computer scientists, and network engineers led by the California Institute of Technology (Caltech) and partners from the University of Michigan, Fermilab, Brookhaven National Laboratory, CERN, San Diego (UCSD), Florida (UF and FIU), Brazil (Rio de Janeiro State University, UERJ, and State Universities of São Paulo, USP), Korea (Kyungpook National University, KISTI), Estonia (NICPB) and the National University of Science and Technology in Pakistan (NUST), joined forces to capture the Bandwidth Challenge award for massive data transfers during the SuperComputing 2009 (SC09) conference.

New Records

The focus of the exhibit was the HEP team's record-breaking demonstration of storage-to-storage data transfer over wide area networks from two racks of servers and a network switch-router on the exhibit floor. The high-energy physics team's demonstration "Moving Towards Terabit/sec Transfers of Scientific Datasets: The LHC Challenge" achieved a bi-directional peak throughput of 119 gigabits per second (Gbps) and a data flow of more than 110 Gbps that could be sustained indefinitely among clusters of servers on the show floor and at Caltech, Michigan, San Diego, Florida, Fermilab, Brookhaven, CERN, Brazil, Korea, and Estonia.
Following the Bandwidth Challenge the team continued its tests and demonstrated a world-record data transfer between the Northern and Southern hemispheres, sustaining 8.26 Gbps on each of two 10 Gbps links linking São Paulo and Miami.
