A service-oriented WSRF-based architecture for metascheduling on computational Grids

This paper describes a Grid service developed over the Globus Toolkit 4, which provides multi-user resource brokering on computational Grids. Both the architecture and implementation details are covered, emphasising the usage of the WSRF specifications and GSI-based security to create a generic, secure and interoperable metascheduler. In addition, we also describe the development of a graphical client-side application that provides an ubiquitous access to the metascheduler service. This work is currently being employed in production for the execution of a biomedical application that simulates the electrical activity of cardiac tissues.
