Extreme Computing on the Distributed European Infrastructure for Supercomputing Applications - DEISA

Abstract

Scientists’ dream of accessing any supercomputer in the world, independently from time and space, is currently coming true, to perform even larger and more accurate computer simulations, at their finger tip. Today, high-speed networks transport data at the speed of light, middleware manages distributed computing resources in an intelligent manner, portal technology enable secure, seemless, and remote access to resources, applications, and data, and sophisticated numerical methods approximate the underlying mathematical equations in a highly accurate way. With the convergence of these core technologies into one complex service oriented architecture, we see the rise of large compute and data grids currently being built and deployed by e-Infrastructure initiatives such as DEISA, EGEE, NAREGI, and TERAGRID.

With the aid of one example, in this keynote presentation, we will elaborate on the Distributed European Infrastructure for Supercomputing Applications, DEISA, which recently entered its second phase. We will describe the system architecture, called the DEISA Common Production Environment (DCPE) and the DEISA Extreme Computing Initiative DECI attracting scientists all over Europe to use the networked supercomputing environment, and we will highlight a few impressive success stories from scientists who achieved breakthrough results so far which would not have been possible without such an infrastructure. Finally, we will summarize main lessons learned and provide some useful recommendations.
