  1. Joint meeting: EchoGrid, Bridge, GridComp and ETSICROWN: A Service Grid Middleware Chunming Hu hucm@buaa.edu.cn Institute of Advanced Computing Technology School of Computer Science & Engineering Beihang University October 31, 2007, CNIC

  2. CROWN Overview • CROWN China Research and Development environment Over Wide-area Network • Jointly Funded by • National Natural Science Foundation of China • NSFC eScience Program • Ministry of Science and Technology of China • 863 Hi-Tech Program, OMII-China Project • 973 National Foundemental Research Program, iVCE Project • CROWN is • A Grid Middleware Suit • A set of tools to support the computer sharing • An infrastructure to provide security and trust to the resource sharing and collaborate scenario • A toolbox to support the application development • A testbed to verify the grid related technologies

  3. Key Components of CROWN • UI • CROWN Portal • CROWN Home: Rich Client Framework • Grid Infrastructure • CROWN NodeServer • CROWN RLDS • CROWN Scheduler • CROWN Domain Authentication/Authorization Service • CROWN Identity Mapping Service • CROWN Workflow Engine • Grid Developing Tools • CROWN Designer

  5. IDEs and PSEs • CROWN Portal • A JSP-based Web Portal to integrate the administration functionalities and application interactions • Plug-in structure to support the different applications • Integrated with MyProxy: Certificate Management • Rich Client Framework • For applications with more interactions • Better plug-in management mechanism: Eclipse RCP • IDE for developers • CROWN Designer: • Provide wizard to create new Grid services: wsdl generator, stub generator, archive creation • Link to a Grid testbed: monitoring, deploying, … • GUI-based Workflow modeling tool as a plug-in

  6. IDEs and PSEs CROWN Designer

  7. Programming Model • Depends on the application scenario • Workflow • GUI: plug-in for CROWN Designer, GUI-based modeling • XML Format: BPEL extension • Objects API: Process management • Master worker (slave): • based on meta-scheduler, especially customized scheduler • MPI-support: local scheduler (OpenPBS integration)

  8. Programming Model

  9. Data Management • In CROWN, we provide a simple, service-oriented solution to provide a virtual file space, and a file access interface • File Transfer • GridFTP, FTP, HTTP(s) • Virtual File System • Meta Data Service: linked with each other to create a tree • Local Data Service: just mount the available space to the tree • Replica Management: create data replications on demand • Database support • Using of OGSA-DAI

  10. Resource management and SLA • Meta scheduler: CROWN Scheduler • A BES implementation • Integration with a local scheduler (say, the batch system) • Using the OpenPBS as the intra-cluster job dessemination • Interact with OpenPBS to monitor the job execution • Hardware resource handled by middleware • Monitoring the system parameters: CPU usage, memory usage, queue length, available disk space… • Control: Soft-control on CPU capability allocation • SLA management: • Not integrated into the current CROWN version • Approach: Define different service level, and mapping different resource capability • Tracking of the resource usage • Security • Message Level Security: WS-Security specifications • Attribute Certificate based: Authentication/Authorization • Authentication support: User/password & X.509 & Kerberos • Automatic Trust Negotiation: to support the trust remote deployment of services

  11. Orthogonal Questions • Globus based or not? YES, but… • CROWN 2.5.3 is based on Java WS-Core • We do have a service container: XServces. Migration is possible. • Approach to SOA? YES • Main Language API: Java • Other implementation can be wrapped by a service interface • Portability across platform: Based on Java Portability • Interoperability with other Grid middleware • JSDL+ BES: Job submission demo on SC2006 and OGF 20 • With Globus, OMII, gLite, Unicore, … • CNGrid GoS (OMII-China) • Information model is not the same

  12. Applications • List of successfully executed applications • eScience: MDP, AREM, gViz, Remote Control of Microscopes AREM Remote execution scenario MDP Master and Slave model

  13. Distribution model • Conditional Open Source: a modified BSD license • Binary code are opened for download • Source code are opened for partners only • Computer Network and Information Center, CAS • Institute of Automation, CAS • Institute of Atmosphere Physics, CAS • White Rose Grid Team, Leeds University, UK • OMII, University of Southampton, UK • …… • No commercial support • Provide help desktop under the OMII-EUROPE project

  14. Future Plans • Performance optimization • Thread management for systems… • Interoperability • BES+JSDL: • Information model: GLUE? CIM? • Integration with Virtual Machine technology • Requirements of service isolation • System protection: Running services created by other people? • Is it possible to create the VM on demand, and kill the VM after the execution of task? (Just like Globus Virtual Workspace) • A key feature of CROWN 3.0

  15. Thank you!

  16. Security Architecture for CROWN Domain CA Node 1 Domain Authentication Service Node 2 Domain Authorization Service … Node n Domain 1.1 Region 1 Region 2 Region KDC Region CA Identity Mapping& Credential Converting Service Domain KDC Node 1 Domain Authentication Service Node 2 Domain Authorization Service … Node n Domain 2.1

  17. CROWN Home CROWN Home: provided GUI for NodeServer Eclipse RCP based GUI Desktop users Java Code Security in NodeServer CPU/Memory/Disk quota Visualized Security & Certificate Management

  18. Future Plans • CROWN 3.0: • CIVIC: CROWN Infrastructure for Virtual Computing, by • Offering the separated and isolated computing environment for end users • Realizing hardware and software consolidation and centralized management. • Providing a transparent view to upper layer applications, by hiding the dynamicity, distribution and heterogeneousness of underlying resources.
