Grid-based Information Architecture for iSERVO at WPGM Beijing Convention Center

This presentation discusses the grid-based information architecture for iSERVO at the Western Pacific Geophysics Meeting (WPGM) held at Beijing Convention Center on July 26, 2006. It explores the role of information technology and grids in earthquake and tsunami prediction, numerical simulations, engineering design, economic analysis, sensor networks, high-performance computing, and more.

  1. Grid-based Information Architecture for iSERVO International Solid Earth ResearchVirtual Organization Western Pacific Geophysics Meeting (WPGM) Beijing Convention Center July 26 2006 Geoffrey Fox Computer Science, Informatics, Physics Pervasive Technology Laboratories Indiana University Bloomington IN 47401 http://grids.ucs.indiana.edu/ptliupages/presentations/ gcf@indiana.eduhttp://www.infomall.org

  2. APEC Cooperation for Earthquake Simulation • ACES is a seven year-long collaboration among scientists interested in earthquake and tsunami predication • iSERVO is Infrastructure to supportwork of ACES • SERVOGrid is (completed) US Grid that is a prototype of iSERVO • http://www.quakes.uq.edu.au/ACES/ • Chartered under APEC – the Asia Pacific Economic Cooperation of 21 economies

  4. Role of Information Technology and Grids in ACES Numerical simulations of physical, biological and social systems Engineering design Economic analysis and planning Sensor networks and sensor webs High performance computing Data mining and pattern analysis Distance collaboration Distance learning Public outreach and education Emergency response communication and planning Geographic Information Systems Resource allocation and management

  5. Grids and Cyberinfrastructure • Grids are the technology based on Web services that implement Cyberinfrastructure i.e. support eScience or science as a team sport • Internet scale managed services that link computers data repositories sensors instruments and people • There is a portal and services in SERVOGrid for • Applications such as GeoFEST, RDAHMM, Pattern Informatics, Virtual California (VC), Simplex, mesh generating programs ….. • Job management and monitoring web services for running the above codes. • File management web services for moving files between various machines. • Geographical Information System services • Quaketables earthquake specific database • Sensors as well as databases • Context (dynamic metadata) and UDDI system long term metadata services • Services support streaming real-time data

  7. SERVOGrid has a portal The Portal is built from portlets – providing user interface fragments for each service that are composed into the full interface – uses OGCE technology as does planetary science VLAB portal with University of Minnesota

  9. Linking Grids and Services • Linkage of Services and Grids requires that messages sent by one Grid/Service can be understood by another • Inside SERVOGrid all messages use • Web service system standards we like (UDDI, WS-Context, WSDL, SOAP) and • GML as extended by WFS so that data sources and simulations all use same syntax • All other Web service based Grids use their favorite Web service system standards but these differ from Grid to Grid • Further there is no agreement on application specific standards – not all Earth Science Grids use OGC standards • OGC standards include some capabilities overlapping general Web Services • Use of WSDL and SOAP is agreed although there are versioning issues • So there is essentially there is no service level interoperability between Grids but rather interoperation is at diverse levels with shared technology • SQL for databases, PBS for Job scheduling, Condor for job management, GT4 or Unicore for Grids

  10. Grids in Babylon • Presumptuous Tower of Babel (from the web) • In the Bible, a city (now thought to be Babylon) in Shinar where God confounded a presumptuous attempt to build a tower into heaven by confusing the language of its builders into many mutually incomprehensible languages. • For Grids, everybody likes to do their own thing and Grids are complex multi-level entities where no obvious points of interoperation • so one does not need divine intervention to create multiple Grid specifications • But data in China, Tsunami sensors in Indian ocean and simulations in USA etc. will not be linked for better warning and forecasting unless the national efforts can interoperate • Two interoperation strategies: • Make all Grids use the same specifications (divine harmony) • Build translation services (filters!) using say OGF standards as a common target language (more practical) • Don’t need computers (jobs) to be interoperable (although this would be good) as each country does its own computing • Rather need data and some metadata on each Grid to be accessible from all Grids

  11. Interoperability Summary • Need to define common infrastructure and domain specific standards • Build Interoperable Infrastructure gatewayed to existing legacy applications and Grids • Generic Middleware • Grid software including workflow • Portals/Problem Solving environments incl. visualization • We need to ensure that we can make security, job submission, portal, data access (sharing) mechanisms in different economies interoperate • Geographic Information Systems GIS • Use services as defined by Open Geospatial Consortium (Web Map and Feature Services) http://www.crisisgrid.net/ • Earthquake/Tsunami Science Specific • Satellites, sensors (GPS, Seismic) • Fault, Tsunami … Characteristics stored in databases need GML extensions - Schema for QuakeTables developed by SERVOGrid can be used Internationally

National Earthquake Grids of Relevance • APAC –GT2 GT4 gLite • ACcESS – Some link to SERVOGrid • China National Grid – GOS GT3 GT4 • ChinaGrid – CGSP built on GT4 • CNGI – China’s Next Generation Internet has significant earthquake data component • Naregi – Uses GT4 and Unicore with much enhancements • Japanese Earthquake Simulation Grid – unclear • K*Grid Korea Enhanced SRB, GT2 to GT4 • TIGER Taiwan Integrated Grid for Education and Research unclear technology and unclear earthquake relevance • SERVOGrid – Uses WS-I+ simple Web Services • TeraGrid – Uses GT4 but not a clear model except for core job submittal
