The paper presents a hierarchical model for integrating structured HPC legacy software modules into a grid-adaptive scientific library service able to deliver quality computing-service on a performance contract basis. The service proactively administers both computing resources and configurable library software modules on behalf of client applications, and seamlessly supports their re-configuration according to grid-aware strategies of active managers of client applications. The library administrator logic mimics functionalities of components containers of service-oriented architectures. The authors discuss the coordination of library-serviced components into grid-aware applications composed according to the programming model being developed by the Italian Grid.it Project. Sample architecture for the library service, based in Grid.it component technology, is sketched

Abstract
The paper presents a hierarchical model for integrating structured HPC legacy software modules into a grid-adaptive scientific library service able to deliver quality computing-service on a performance contract basis. The service proactively administers both computing resources and configurable library software modules on behalf of client applications, and seamlessly supports their re-configuration according to grid-aware strategies of active managers of client applications. The library administrator logic mimics functionalities of components containers of service-oriented architectures. The authors discuss the coordination of library-serviced components into grid-aware applications composed according to the programming model being developed by the Italian Grid.it Project. Sample architecture for the library service, based in Grid.it component technology, is sketchedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
