Download slides (pdf 5.96 MB) In this talk we present the status of the Community Services project. The project goal is to promote the deployment of stable services on the Grid, enhancing end-user productivity and improved resource utilization. One of the challenges we are addressing is adapting to the dynamic behavior of the environment along several dimensions: resource availability may be fluctuating, user service demand may be unpredictable, and user service interest may be changing. All of these problems suggest that adaptivity must be employed at various levels in the system. We are developing a robust system architecture, middleware, and testbed to demonstrate the utility of our approach. Some novel features include: (1) an architecture that supports dynamic and remote service installation in the Grid, (2) the classification of adaptive services into utility-based resource providers and application-level services, (3) reusable middleware that provides a "mixture of experts" in support of resource management, and (4) a stochastic leasing model for hosting services on resources.
