  1. Enabling Discoveries in the Earth Sciences Through the Geosciences Network (GEON) Dogan Seber San Diego Supercomputer Center University of California, San Diego

  2. Outline • Introduction and History of GEON • System Architecture • GEON Portal and the Resource Access Mechanisms • Use Case Scenarios • HPC Application Development within GEON

  3. GEON • NSF Large ITR project – collaborative effort • GEON is creating an IT infrastructure to “enable” interdisciplinary geoscience research for the entire community • Project started in October 1, 2002 (after three years of preparation) and will continue until September 30, 2007

  4. GEON’s Vision • Enable new discoveries in the geosciences by utilizing an easy-to-use “integration environment” built using state-of-the-art information technology resources. The end product is a system that : Enables new interdisciplinary research and encourages resource sharing Stores and seamlessly integrates distributed data sets, software, and toolsAllows users to make searches to discover data and information not only by name, but also by concepts. Provides high-end computational resources Provides a customizable analysis and research environment (workflow) Is a rich resource for teachers and learners

GEON: Geosciences Network Metadata Services Others GEON Catalog GEON Portal Web/Grid Services Interfaces Registration GEONsearch GEONworkbench workflow, visualization, HPC MyGEON Data Integration Services Computational & Modeling Services Data Registration Services Mapping Services Ontology Enabled Integration ArcIMS WMS WFS Modeling, Analysis Tools Logging Services Indexing Services Other Core Services Data Services Usage Stats Collection & Analysis Spatial Temporal Conceptual GridFTP OGSA-DAI CSF SRB OpenDAP DB2, Postgres mySQL Physical Grid RedHat Linux, ROCKS, OGSI, Internet, I2

  6. GEON Cyberinfrastructure Principles • An equal partnership • IT works in close conjunction with science • CI: Support the “day to day” conduct of science (e-science), in addition to “hero” computations • The “two-tier” approach • Use best practices, including use of commercial tools and open standards, where applicable… • …while developing advanced technology, and doing CS research • Create shared “science infrastructure” • Integrated online databases, with advanced search and query engines • Online models, robust tools and applications • Leverage from and work with other intersecting projects • Much commonality in the technologies, regardless of science disciplines, e.g. BIRN, SEEK, and many others
