2 Virtual Organizations (VO)
Instances of Virtual Organizations (VOs) Virtual organizations offer a community of practice the opportunity to work together - sharing expertise, tools, information and facilities. People* People* People* Interfaces for interaction, workflow, visualization and collaboration for individuals & distributed teams Alternate Names for VOs: • Co-laboratory • Collaboratory • Grid (community) • Network • Portal • Gateway • Hub • Virtual Research Environment • Other? Mechanisms for flexible secure, coordinated resource/services sharing among dynamic collections of individuals, institutions, and resources (the Grid or service layer problem) Facilitate scientific workflows • Collaborate on experiments Share information & knowledge Remotely operate instruments Access wide range of computing resources Archive, e-publish, access, mine, analyze and visualize data Develop new computational models Deliver unique learning and workforce development activities Distributed, heterogeneous services for: Computation Data, information management Sensing, observation, activation in the world October 31, 2006 Office of CyberInfrastructure * People engaged in discovery and learning as individuals and in teams

4 Virtual Organizations: NSF Goals
To catalyze the development, implementation and evolution of functionally-complete national cyberinfrastructure … To promote and support the establishment of world-class VOs that are secure, efficient, reliable, accessible, usable, pervasive, persistent and interoperable … To support the development of common cyberinfrastructure resources, services, and tools … NSF’S CYBERINFRASTRUCTURE VISION FOR 21ST CENTURY DISCOVERY, October 31, 2006 Office of CyberInfrastructure

5 TeraGrid Science Gateways Community Interface to Grids
Type 1 — A gateway that is packaged as a web portal with users in front and TeraGrid services in back. Type 2 — Grid-bridging Gateways: often communities run their own Grids devoted to their areas of science. In these cases the Science gateway is a mechanism to extend the reach of the community Grid so it may use the resources of the TeraGrid. Type 3 — A gateway that involves application programs running on users' machines (i.e. workstations and desktops) and accesses services in TeraGrid (and elsewhere). The objectives of the TeraGrid Science Gateways initiative include working with many gateway projects and peer grid projects to define interaction protocols, mechanisms and policies such that gateways can be developed to operate with TeraGrid as well as other grid infrastructures and facilities. This collaborative approach involves international workshops and TeraGrid leadership in initiatives such as the “Grid Interoperation Now” (GIN) group, consisting of some 20 grid facilities from around the world pursuing interoperation in several specific areas during GIN uses the Global Grid Forum as an administrative home for the activities, see forge.ggf.org.

6 TeraGrid Science Gateway Partners
Open Science Grid (OSG) Special PRiority and Urgent Computing Environment (SPRUCE, UChicago) National Virtual Observatory (NVO, Caltech) Linked Environments for Atmospheric Discovery (LEAD, Indiana) Computational Chemistry Grid (GridChem, NCSA) Computational Science and Engineering Online (CSE-Online, Utah) GEON(GEOsciences Network) (GEON, SDSC) Network for Earthquake Engineering Simulation (NEES, SDSC) SCEC Earthworks Project (USC) Astrophysical Data Repository (Cornell) CCR ACDC Portal (Buffalo) • Network for Computational Nanotechnology and nanoHUB (Purdue) • GIScience Gateway (GISolve, Iowa) • Biology and Biomedicine Science Gateway (UNC RENCI) • Open Life Sciences Gateway (OLSG, UChicago) • The Telescience Project (UCSD) • Grid Analysis Environment (GAE, Caltech) • Neutron Science Instrument Gateway (ORNL) • TeraGrid Visualization Gateway (ANL) • BIRN (UCSD) • Gridblast Bioinformatics Gateway (NCSA) • Earth Systems Grid (NCAR) • SID Grid (UChicago) Science Gateway partners are projects who have agreed to work with TeraGrid to help define processes and mechanisms by which TeraGrid services and resources can be used in the “back end” of their portals, grids, or desktop applications. Each project listed here is unique in terms of its maturity or readiness, or use of TeraGrid. Many are in the early developmental stages, while some are fully operational. The TeraGrid Science Gateways program is coordinated by the Grid Infrastructure Group under leadership from Nancy Wilkins-Diehr at the San Diego Supercomputer Center. (
