Towards On-Demand Ubiquitous Metascheduling on Computational Grids

Grid computing technologies are mature enough to be successfully applied to computationally intensive scientific applications. However, the current process of applying grid computing to them is still hard and difficult for the least experienced users. In this paper we describe the adaptations made to the GMarte metascheduling framework in order to provide an ubiquitous access to its functionality as an efficient resource broker for the execution of tasks on computational grids. A metascheduling component accessible by only means of a Java-enabled Web browser has been developed, requiring almost zero configuration by the client. This approach has enabled to produce a generic multi-platform metascheduler which can be automatically deployed in the clients interested in resource brokering on computational grids based on the Globus Toolkit
