11. CNGrid GOS organization 自主开发的源代码约35万行2.0版安装包共有110 MB代码

12. Deployment of CNGrid GOS

13. Prospects of CNGrid • CNGrid will be connected to CNGI-a IPv6 network in China • Multi-protocol support • modification and upgrade of CNGrid GOS • Transparent to applications • CNGrid will become the basis of the network computing environment of China • Regular operation • It is very possible that CNGrid will be continually supported by 863 program

14. Interconnection of CNGrid and EU Grid Infrastructure • Some issues has to be addressed for effective cooperation • Precondition • Reasonable network bandwidth • Interoperability and inter-operation of European and Chinese Grid infrastructures • Harmonization of the security mechanism • Mutual interests in applications

15. Interoperability of CNGrid GOS and EU Grid software • How to achieve interoperability of different Grid software • Different software installation to the same infrastructure? • How is it viewed by the applications?

16. Resource management and monitoring • CNGrid has a resource monitoring system for management and scheduling • Exchange monitoring information between different systems or using the same monitoring tool? • How will the scheduling issue be handled?

17. Data access and Integration • File and database level sharing • OGSA-DAI? • Other data grid software? • Sharing data is crucial for research an other applications

18. User management • Building and managing VOs • Authentications • Authorizations

19. Security • Crucial for interconnection • Harmonization of security polices and CA mechanisms

20. Accounting • Setting up Grid business model • Cost issues to be addressed • Preparing for future Grid service business

21. User and development environment • Portal based • Integrated Grid programming and application development environment is required • Application development support • Service components • Workflow

22. Deployment of Applications • Deploy the current applications to other infrastructure • Jointly developing and deploying new applications

23. Testing and training environment • Setting up an environment for training and testing in parallel with operational infrastructure • Interoperability testing • Upgrading to Ipv6 • Developing and testing new applications • Providing training facility • Less disturbance to the operational infrastructure

24. User training • Tutorial on Grid software and tools • Training and tutorial on applications • Training technical support people

25. What we need to do for interconnection • Supporting Grid software interoperability study, deploy different software in the environment • Deploying current applications and developing an deploying new applications on extended infrastructure • Supporting harmonized security mechanism • Supporting testing and training

26. Thanks!
