SC2002 BANDWIDTH CHALLENGE WINNERS SET NEW NETWORK PERFORMANCE MARKS
Prizes for most daring networking awards sponsored by Qwest Communications
November 27, 2002--The High-Performance Bandwidth Challenge awards announced last week at SC2002 established new records for network performance, with one winning application demonstrating a five-fold increase over the previous top-mark set last year. The High-Performance Bandwidth Challenge, held at the annual SC Conference, is a competition for leading-edge network applications developed by teams of researchers from around the world.
For the third consecutive year, a team led by Lawrence Berkeley National Laboratory captured the competition for the "Highest Performing Application" with a wide area distributed simulation using Cactus, Globus and Visapult software demonstrating a peak data transfer rate of of 16.8 gigabits per second, nearly 25,000 times faster than a typical home broadband connection. The winning team included the Albert Einstein Institute, Argonne National Laboratory, ESnet, Force10 Networks,Masaryk University, the National Center for Supercomputing Applications (NCSA), the National Energy Research Scientific Computing Center (NERSC), Poznan Supercomputing and Networking Centers, Sandia National Laboratories, and the University of Amsterdam.
The Data Reservoir application, demonstrated by Fujitsu Laboratories and University of Tokyo, won the award for the "Most Efficient Use of Available Bandwidth," with a peak of 585 megabits per second.
With a peak transfer rate of 2.4 gigabits per second, the award for the "Best Use of Emerging Network Infrastructure" went to Project DataSpace, which was demonstrated by a team from CANARIE, the National Center for Data Mining at the University of Illinois at Chicago, Northwestern University, SARA (Stichting Academisch Rekencentrum) and StarLight.
Ten outstanding entries third edition of the High-Performance Bandwidth Challenge was again sponsored by Qwest Communications and attracted Additional network monitoring and measurement support was provided by CalNGI, Internet2, the National Partnership for Advanced Computational Infrastructure, the San Diego Supercomputer Center, Spirent Communications, and the University of Florida.
The competition took place live on the SC2002 show floor in Baltimore using SCinet, the state-of-art, on-site network designed and built especially for the annual SC conference. SCinet featured more than 40 gigabits per second (Gbps) of external network capacity, itself a new record and more than 50,000 times the speed of a typical home broadband connection.

Lambda Join Demonstration Wins Award at Supercomputing 02 Conference
November 21, 2002
Baltimore, Maryland. Project DataSpace, in a collaborative project with researchers from Chicago, Ottawa and Amsterdam, has won the SuperComputing '02 High Performance Bandwidth Challenge Award for Innovative, High Speed, Data Correlation--Best Use of Emerging Infrastructure. The group includes researchers from the National Center for Data Mining at the University of Illinois at Chicago (UIC), CANARIE, and SARA, who have been working together over the past year to produce real-time merging of data over lambda networks. At SC02, they presented the first demonstration of the technology, with impressive results.
For the past two decades, database researchers have optimized the ability of databases to join two tables in a database by a common key, such as an employee or product ID. Database joins are one of the key technologies that make data processing practical.
As more and more data is distributed over the internet, the ability to join data located in two different global locations is becoming critical. There are two fundamental problems: finding efficient protocols to move data over long distances and finding efficient algorithms to merge two data streams.
At the Supercomputing '02, significant progress was made on both fronts.
A stream of data was moved over SURFnet connecting a cluster of computers at SARA Computing and Networking Services in Amsterdam and a cluster of computers at StarLight in Chicago at over 2.8 Gb/s. At the same time a stream of data was moved over Canada's CA*net4 network connecting a computer cluster at CANARIE in Ottawa and a UIC computer cluster at StarLight in Chicago at over 2 Gb/s. Both streams used a new protocol called SABUL designed for high performance data transport developed by the National Center for Data Mining/Laboratory for Advanced Computing at the University of Illinois at Chicago.
At the same conference, using computer clusters at the StarLight facility in Chicago, two streams of data were merged at over 500 Mb/s per node in the three node cluster. These so called "lambda joins" are an important component for distributed data mining applications. The algorithm for joining two lambda streams was developed by scientists at the National Center for Data Mining at the University of Illinois at Chicago.
"Lambda data joins are an excellent early example of how CA*net4's lightpath provisioning facility can be used to help build new and innovative distributed services,' according to Bill St. Arnaud, Senior Director for Advanced Networks at CANARIE.
To many network engineers, lambda and lightpath are used interchangeably to describe a low layer end-to-end dedicated communications channel of effective guaranteed bandwidth. Using protocols such as SABUL, it is now possible to use lambdas to move large data sets over long distances as fast as the data can be pulled from disk. Using lambda joins, it is now possible to merge two such streams and look for patterns.
"With lambda joins, it is now practtical to look for correlation in data even if the data is scattered around the world," said Robert Grossman, Director of the National Center for Data Mining at the University of Illinois at Chicago and President of the Two Cultures Group.
This demonstration was awarded one of the three Quest Bandwidth Challenges Awards presented at this year's Supercomputing 02 Conference.
