  1. OGSA Based MetaService Architecture Zhihui Du Associate Professor Department of Computer Science and Technology Tsinghua University, Beijing 100084, P.R. China Phone: 86-10-62782530 Email: duzh@tsinghua.edu.cn

  2. Grid Service Grid Service Grid Service Grid Service Grid Resources Computer Storage Device ... OGSA(Open Grid Services Architecture) Overview • Open standard of Grid Computing • Service Oriented Model/Architecture • Question: How to manage so many grid resources or grid services? • Answer: MetaServices

  3. Grid Service Grid Service Grid Service Grid Service Raw Grid Resources Computer Storage Device ... MetaServices Concept • MetaService: the Grid Service which is used to manage other grid services(resources), MetaService Resource Service Grid Applications High Level Grid Middleware MetaService MetaService MetaService Managed Grid Resources

  4. Monitoring Optimizing Adjusting Grid Services M A O O A O M O M A O A High level MetaService Low level MetaService Low level MetaService MetaServices Architecture • MetaServices Building Blocks: Monitoring/Optimizing/Adjusting • MetaServices Directed Graph {Mi,Oj,Ak}->{Mi’,Oj’,Ak’} • Layered MetaServices

  5. Grid Service Consumers MetaServices Grid Service Providers How MetaServices work? • User transparent • grid services consumer:any grid entity using the other grid services (resources) • grid service provider:any grid entity providing service to other grid services • Providing better services(better performance/easier to use or maintain) to service consumers

  6. IBM:Management of ResourcesAutonomic Computing • Self-optimizing • Self-configuring(adjusting) • Self-healing(adjusting) • Self-protecting(adjusting)

  7. Prototype: PC Monitoring Services • Based on GT3 • Register to http://166.111.68.187:8080/csipgrid/index.jsp • Download a client side • Install it
