Trustworthy Distributed Computing: CROWN Project Prof. Jinpeng Huai, Beihang University crown@ http:// Agenda Research Programs CROWN Project Research Programs CROWN: China Research and Development Environment Over Wide-area Network 2004 – 2006, National Science Foundation of China (NSFC) Goal: Providing Grid-enabled research environment for scientists Resource Sharing Collaborating Trustworthy Distributed Computing Grid Infrastructure Research Construction CROWN Outline Research Programs CROWN Project CROWN Project CROWN resource organization CROWN middleware CROWN Security Pilot applications International collaboration 1.CROWN Resource Organization 2.CROWN Middleware Architecture 2.CROWN Middleware CROWN Node Server WSRF-compliant grid service container Base services: resource monitoring and service deployment Key features Hot/Remote/Secure service deployment Dynamic resource information collecting Overlay for Grid Computing ROST: Remote Hot Service Deployment with Trustworthiness in CROWN the remote hot deployment by dynamically updating the runtime environment configuration and therefore avoiding restarting the runtime system. In addition, we add trust negotiation for remote service deployment, which greatly increases flexibility and security of CROWN. 2.CROWN Middleware CROWN RLDS Resource Locating and Description Service GIMS: Grid Information Model Service Resource Information publish finding Dynamic topology management Advanced GIQL Query Overlay for Grid Computing Efficient Information Service Management Using Service Club in CROWN existing information service architectures suffers from poor scalability, long search response time, and huge traffic overhead. Handle resource discovery and management process In S-Club, an overlay based on existing GIS mesh network of CROWN is built, so that GISs are organized as service clubs. Each club serves for a certain type of service while each GIS may join one or more clubs. Performance of S
