  2. SERVOGrid Grid Requirements • Seamless Access to Data repositories and large scale computers • Integration of multiple data sources including sensors, databases, file systems with analysis system • Including filtered OGSA-DAI • Rich meta-data generation and access with SERVOGrid specific Schema extending industry standards • Portals with component model for user interfaces and web control of all capabilities • Collaboration to support world-wide work • Basic Grid tools: workflow and notification

  3. What should SERVOGrid do ? • Make use of Grid technologies and architecture from around the world • Coordinate with broad community through Global Grid Forum and OMII • Decide on domain specific standards SERVOGridML • Agree on particular approach within choices in international suite (use GT3 or not?, use portlets or not?, choose meta-data technology) and define SERVOGrid community practice • Develop software system infrastructure and applications specific to solid earth science • Worry about network interconnection between earthquake scientists and sensors

  6. Discussion I • People • Compute Nodes • ACcESS SGI Altix • RIST Intel/Myrianet • University of Tokyo • VPAC Alpha/Quadrics • Indiana IBM SP • NASA Ames probably • Issues • Data formats/translation service for input and output data • Need list of software, databases • Security • Visualization

  7. Discussion II • Grid Software Components • Core Infrastructure – Apache Axis • Metadata Catalog/Registry e.g. Globus MDS but maybe can be done as now in Gateway (as implement for NASA JPL project) • Databases – Xindice MySQL plus OGSA-DAI • Workflow – Gateway • Job Submission – Gateway • Portlets for User Interface – Apache Jetspeed

  8. Discussion III • Process • email, shared internal web pages, external -- iSERVO • Desktop AV, Conferencing • Activities • Identify responsible people • Debug collaboration infrastructure • Tutorial from Marlon on current US Project • July 2003 • Analyze test cases for hardware, software, data • Policy on machines/data access -- implications
