The following is excerpted from the Project Summary of that proposal: As a comprehensive computational, data management, and networking environment of unprecedented scale and capability, the TeraGrid will be the enabling cyberinfrastructure for 21st century U.S. science and engineering. Operating as a single distributed resource that is co-allocated and scheduled, the TeraGrid will support both traditional scientific computing and emerging disciplinary scientific groups. A unified TeraGrid Operations Center will coordinate system management, user support, and access. … By engaging vendors, application researchers, computing experts, and government collaborators in a partnership that leverages the explosive growth of Grid technology, open source software, and high-performance commodity hardware, we can deploy a cyberinfrastructure far more powerful and flexible than any single supercomputing system, catalyzing scientific discovery across broad disciplines. This vision was the basis for the TeraGrid. Its fundamental message has not significantly changed, but our understanding of what it fully means and what it implies has changed over the life of the project. As envisioned, the TeraGrid’s impact to science and engineering has been profound. An astounding amount of work has been enabled by the TeraGrid’s systems and integrated services, at all levels. This can be seen in the annual Science Highlight booklet produced by TeraGrid. These examples have come from a variety of fields, including astrophysics, material science, climate, biomolecular science, medicine, geophysics, energy, fluid dynamics, weather, particle physics, imaging physics, literature and text studies, electronic structures, economics, machine learning, bioinformatics, epidemiology, network analysis, and ecology. A number of these were not anticipated a decade or more ago when the original TeraGrid proposal was written. These highlights are but a subset of the nearly 9,000 peer-reviewed publications supported by TeraGrid. Scientists and engineers have been successful because TeraGrid made user success one of its highest priorities. The infrastructure and supporting services catalyzed and supported an increasing number of collaborative science, computer science, and computational science teams allowing complex questions to be addressed in multiple domains. The TeraGrid encouraged not only U.S., but also global collaborations, which led to new science and new capabilities. Non- U.S. scientists have been able to make use of TeraGrid resources as part of collaborations with U.S. scientists. This has facilitated the work of the U.S. partners, and helped TeraGrid by bringing in leading-edge users who had demands that foreshadowed future user needs. The TeraGrid not only provided a single-system information and support interface for using all the National Science Foundation’s (NSF) Office of Cyberinfrastructure (OCI) funded supercomputers, it also pioneered various successful mechanisms for engaging broader communities. The Science Gateways program has had tremendous impact on the way researchers and educators alike go about their business. Simplified interfaces to domain-specific tools hid many of the complicated details of running on HPC resources, lowering the bar of entry and enabling a wider community of users. The Campus Champions program enrolled volunteer faculty and IT staff members from universities across the country

  • The Neutron Science Teragrid Gateway, a Teragrid Science Gateway to Support the Spallation Neutron Source
    The Neutron Science TeraGrid Gateway, a TeraGrid Science Gateway to Support the Spallation Neutron Source John W. Cobb*, Al Geist*, James A. Kohl*, Stephen D. Miller‡, Peter F. Peterson‡, Gregory G. Pike*, Michael A. Reuter‡, Tom Swain†, Sudharshan S. Vazhkudai∗ , Nithya N. Vijayakumar $ SUMMARY The National Science Foundation’s (NSF’s) Extensible Terascale Facility (ETF), or TeraGrid [1] is entering its operational phase. An ETF science gateway effort is the Neutron Science TeraGrid Gateway (NSTG.) The Oak Ridge National Laboratory (ORNL) resource provider effort (ORNL-RP) during construction and now in operations is bridging a large scale experimental community and the TeraGrid as a large-scale national cyberinfrastructure. Of particular emphasis is collaboration with the Spallation Neutron Source (SNS) at ORNL. The U.S. Department of Energy’s (USDOE’s) SNS [2] at ORNL will be commissioned in spring of 2006 as the world’s brightest source of neutrons. Neutron science users can run experiments; generate datasets; perform data reduction, analysis, visualize results; collaborate with remotes users; and archive long term data in repositories with curation services. The ORNL-RP and the SNS data analysis group have spent 18 months developing and exploring user requirements, including the creation of prototypical services such as facility portal, data, and application execution services. We describe results from these efforts and discuss implications for science gateway creation. Finally, we show incorporation into implementation planning for the NSTG and SNS architectures. The plan is for a primarily portal-based user interaction supported by a service oriented architecture for functional implementation. KEY WORDS: Portal, Neutron Scattering, TeraGrid, Science Gateway, Service Architecture, Grid 1.

  • 1.2 OVERVIEW Campuses & Institutes
    1.2 OVERVIEW Campuses & Institutes Carnegie Mellon has been a multifaceted institution throughout its exis- tence. The original Carnegie Technical Schools, founded in 1900, com- prised four colleges spanning the arts, sciences and vocations. As it later evolved into the Carnegie Institute of Technology, it became a national leader in fields as disparate as engineering and drama. In 1967, it merged with the Mellon Institute for Industrial Re- search, resulting in the modern Carnegie Mellon Univer- sity. Today, the school has branch campuses in California and the Middle East and degree programs in six countries across the world. Carnegie Mellon’s main campus comprises 103 acres in Pittsburgh’s vibrant Oakland neighborhood, where many of the city’s major cultural and scientific institutions are located. Close to 11,000 students and 1,200 full-time faculty conduct their studies here, and Pittsburgh’s long history as an American hub of industrial engineering, finance and arts-oriented philanthropy provides an appropriate backdrop MAIN CAMPUS for the university’s current innovative pursuits. The campus contains more than 50 academic, Pittsburgh, Pennsylvania research and administrative buildings and three libraries. Resource sharing between Carnegie Founded 1900 by Andrew Carnegie; Mellon and other local universities provides students with almost unlimited information resources. seven graduate & undergraduate What’s more, the campus is committed to environmental practices, building new LEED-certified schools spanning the sciences and dorms and buying electricity from a regional wind farm. fine arts www.cmu.edu CARNEGIE MELLON SILICON VALLEY Silicon Valley, California, Founded 2003 Master’s degrees in software engineering and software management http://sv.cmu.edu Carnegie Mellon West graduated its first class in August 2003, with 17 students receiving master’s degrees in information technology with specializations in software engineering, e-business technology and the learning sciences.

TeraGrid is a nationwide, National Science Foundation, or NSF,-funded research infrastructure that incorporates high-performance computing resources at nine sites across the country. The award will fund initiatives for Louisiana researchers to develop broader use of LONI resources as well as underwrite the operations costs associated with joining TeraGrid. As a member of TeraGrid, LONI will contribute one half of its centerpiece supercomputer, Queen Bee’s, computational cycles to the TeraGrid community. LONI researchers will in turn be able to utilize the TeraGrid’s national resources. "It is exciting to see Louisiana's investment in supercomputing technology continue to deliver significant dividends," said Governor Kathleen Babineaux Blanco. "This grant, making possible our participation in the TeraGrid, is further confirmation that Louisiana's technological infrastructure can compete with the best the world has to offer." Charlie McMahon, LONI executive director, served as principal investigator for the NSF grant.
