A Grid-Enabled Adaptive Problem Solving Environment

As complexity of computational applications and their environments has been increased due to the heterogeneity of resources; complexity, continuous changes of the applications as well as the resources states, and the large number of resources involved, the importance of problem solving environments has been more emphasized. As a PSE for metacomputing environment, Adaptive Distributed Computing Environment (ADViCE) has been developed before the emergence of Grid computing services. Current runtime systems for computing mainly focus on executing applications with static resource configuration and do not adequately change the configuration of application execution environments dynamically to optimize the application performance. In this paper, we present an architectural overview of ADViCE and discuss how it is evolving to incorporate Grid computing services to extend its range of services and decrease the cost of development, deployment, execution and maintenance for an application. We provide that ADViCE optimize the application execution at runtime adaptively optimize based on application requirements in both non-Grid and Grid environment with optimal execution options. We have implemented the ADViCE prototype and currently evaluating the prototype and its adaptive services for a larger set of Grid applications.
