18.21 Gbps wins Supercomputing Bandwidth Competition
The award was presented at SC07, the world's largest international conference for high performance computing, networking, storage and analysis, being held this week in Reno, Nevada.
The Bandwidth Challenge competition invites teams of technologists from the nation's most elite supercomputing facilities to push the limits of modern computer networks.
The competition this year was based on the theme "serving as a model". Competitors were challenged to create methods for fully utilizing a high-speed network path to support end-to-end network applications running across a grid that included the conference's exhibit floor and the participant's home institutions using production networks.
Using the IU Data Capacitor, a system designed to store and manipulate massive data sets, the IU team achieved a peak transfer rate of 18.21 Gigabits/second out of a possible maximum of 20 Gigabits/second.
This performance was nearly twice the peak rate of the nearest competitor. The IU team achieved an overall sustained rate of 16.2 Gigabits/second (roughly equivalent to sending 170 CDs of data per minute) using a transatlantic network path that included the Internet2, GÉANT, and DFN research networks.
"This project simultaneously pushed the limits of networking and storage technology while demonstrating a reproducible model for remote data management. Best of all, we did this using a variety of research applications that we support every day at Indiana University," said Data Capacitor and Bandwidth Challenge project leader Stephen Simms.
