The Challenges of Capability Computing and the Teragrid

Attacking a leading-edge problem often requires many facets of capability computing, including different computational architectures, storage, visualization, data handling. The necessary resources are often not co- located. The National Science Foundation is developing the Teragrid as a prototype of how these components can effectively interoperate to facilitate solving important problems. I will briefly describe scientific drivers for this project, its implementation, some early successes and continuing challenges.
