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.
In 2008, High Energy Physicists Created Record for Network Data Transfer
110 Gbps Sustained Rates Among
Storage Systems Over Wide Area Networks, and 200 Gbps Metro Data
Rates on Next Generation Optical Links, Set New Standards for
Networks and Computing Clusters
