4. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 4 Components of GOS  System software (VegaGOS)  global naming management,  VO management,  user management,  resource management,  application runtime management  CA certificate management system  Integration and testing environment  Three business version of sub-systems  high performance computing gateway,  data grid  grid workflow  Monitoring system.

5. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 5 CNGrid GOS Architecture Grid Portal, Gsh+CLI, GSML Workshop and Grid Apps OS (Linux/Unix/Windows) PC Server (Grid Server) J2SE( 1.4.2_07, 1.5.0_07 ) Tomcat( 5.0.28 ) + Axis( 1.2 rc2 ) Axis Handlers for Message Level Security Core, System and App Level Services

6. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 6 CA The CA system provides full functionalities on web portal certificate application, generation, distribution, revocation, status query and management. Three layers ： the Web server, the Function server and the DB server Independent CA system dedicated to CNGrid

7. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 7 Resources management  Resources in VegaGOS are in various forms, and are accessed in different ways.  Resource controller mechanism (RController) is used to import and manage various heterogeneous resources in a unified way.  Provides many functions for resources like create, destroy, access control, access, read and write properties, etc.

8. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 8 Data Management A virtual file system manager that solves the stage in, stage out and data sharing problems in Grid. composed of storage services, mapping services, management portal, and GUI management tool (GUI Man) and command line management tool (CMD Man) for clients.

9. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 9 Future of CNGrid  CNGrid will get support in the next years, but the future is not really clear  Super computing power would be the first priority to be invested.  Moving to Cloud ‘totally’?

10. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 10 Interoperation with gLite  GOS was based on GLOBUS and written in Java  Interoperation between GOS and gLite is the big issue  Previous work was devoted during the EUChinaGrid etc.

11. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 11 Interoperability  Application level:  A test system was developed at IHEP  BESIII jobs can be submitted to gLite (at IHEP) and GOS (at Hong Kong University)  Have to interact with applications  Service level:  GOS Adapter based on JSAGA can be a solution, since we do not need to touch the details of GOS  BUAA and IHEP should be involved

12. Feb. 27, 2012, CHAIN workshop, Taipei G. Chen 12 To Do  Produce a JSAGA adapter for GOS, based on the SAGA standard  This may minimize the touch to GOS codes  The JSAGA adapter can be developed during the EPIKH/CHAIN school in the coming April  BUAA and IHEP will work on the adapter  Deployment and challenge test in the rest of the year.  IHEP will contribute the application deployment
