  3. Cyberinfrastructure (cont) • Software programs, services, instruments, data, information, knowledge, applicable to specific projects, disciplines, and communities. • Cyberinfrastructure layer of enabling hardware, algorithms, software, communications, institutions, and personnel. A platform that empowers researchers to innovate and eventually revolutionize what they do, how they do it, and who participates. • Base technologies: Computation, storage, and communication components that continue to advance in raw capacity at exponential rates. [Paraphrased from NSF Blue Ribbon Panel report, 2003] Challenge: Creating and operating advanced cyberinfrastructure andintegrating it in science and engineering applications. Paul Avery

  4. Cyberinfrastructure and Grids • Grid: Geographically distributed computing resources configured for coordinated use • Fabric: Physical resources & networks provide raw capability • Ownership: Resources controlled by owners and shared w/ others • Middleware: Software ties it all together: tools, services, etc. • Enhancing collaboration via transparent resource sharing US-CMS “Virtual Organization” Paul Avery
