iGrid 2002, the 3rd biennial International Grid applications-driven testbed event, challenges scientists and technologists to utilize multi-gigabit experimental optical networks, with special emphasis on e-Science, LambdaGrid and Virtual Laboratory applications. The result is an impressive, coordinated effort by 28 teams representing 16 countries,... showcasing how extreme networks, combined with application advancements and middleware innovations, can advance scientific research. As computational scientists strive to better understand very complex systems - whether biological, environmental, atmospheric, geological or physics, from the micro to the macro level, in both time and space - they will require petascale computing, exabyte storage and terabit networks. A petaflop is one-hundred-times faster than today's largest parallel computers, which process ten-trillion floating-point operations per second (10 teraflops). An exabyte is a billion gigabytes of storage, and terabit networks will eventually transmit data at one trillion bits per second - some 20 million times faster than a dialup 56K Internet connection. Recent, major technological and cost breakthroughs in networking technology have made it possible to send scores of lambdas on a pair of customer-owned or leased optical fiber, making the terabit network of the future conceivable. (Here, lambda refers to a fully dedicated wavelength of light, each capable of bandwidth speeds from 1-10 gigabits/second.) Research is moving from locally-connected, processor-centric environments to distributed-computing environments that rely on optical connections, where the networks are faster than the resources they connect. Researchers are moving from grid-intensive computing to LambdaGrid-intensive computing, in which computational resources are connected by multiple lambdas. As a conference, iGrid 2002 demonstrates application demands for increased bandwidth. As a testbed, iGrid 2002 enables the world's research community to work together briefly and intensely to ...Read More
