Workflow optimisation for e-science applications

Grid computing is converging on a service-oriented architecture in which applications are composed from geographically dispersed, interacting Web services, and expressed in a workflow description language. The discovery of resources is of key importance to the effective and flexible use of such an architecture. This paper describes work to date in the Workflow Optimisation Services for e-Science Applications (WOSE) project which is investigating techniques for discovering services and optimising the execution of service composite workflows
