Notification Deadline 18 July 2003

Continuing the tradition started at SC2000, SCinet and Qwest Communications are sponsoring the Fourth Annual High Performance Bandwidth Challenge. For the Bandwidth Challenge, applicants from science and engineering research communities across the globe will use the unique SCinet infrastructure to demonstrate emerging techniques or applications, many of which consume enormous amounts of network resources.

At SC2002 in Baltimore, MD, Lawrence Berkeley National Laboratory captured the competition for the "Highest Performing Application" with a wide area distributed simulation using Cactus, Globus and Visapult software that demonstrated a peak data transfer rate of 16.8 gigabits per second, nearly 300,000 times faster than a Internet user with a typical 56K connection.

For SC2003, to be held in Phoenix, AZ November 15-20, 2003, applicants are challenged to significantly stress the SCinet network infrastructure while delivering innovative application value across the multiple research networks that connect to SCinet. For 2003, SCinet anticipates delivery of as many as four OC-192c wide area network interconnects to the Phoenix Convention Center. To support Bandwidth Challenge contestants, SCinet facilitates access to the networks, provides technical support to applicants, and makes arrangements for equipment and floor and rack space to applicants with demonstrable needs.

Potential Contestants Must Submit Notification of Intent to Participate by July 18, 2003.

Upon receipt of this notification of intent, SCinet will contact contestants with instructions on the content and format of the formal proposal. Full proposals must be received by August 8 to be included in the Conference Final Program.

The judging criteria for 2003 have been expanded to include:

1. Measurement of sustained TCP utilization

2. Quality of IPv6 implementation

3. Innovative features of non-stock TCP implementations

4. Applicability to the real world

5. Efficiency and effectiveness of multi-continent implementations

6. Improvement over previously demonstrated method

7. Quality of first time demonstrations

Qwest Communications is sponsoring the award of one or more monetary prizes for the applications that make the most effective and/or courageous use of SCinet resources. The primary measure of performance will be the verifiable network throughput as measured from the contestant's equipment through the SCinet switches and routers to external connections.
