A Distributed Workflow Management Approach in CGSP

Workflow management technologies play a very important role in constructing grid application environment by automating service composition and execution. With the fast spread of grid technology, workflow management system should be flexible to meet increasing requirements of service composition. This paper introduces a distributed workflow management approach DWM4CGSP named distributed workflow management for CGSP, which can improve capability of workflow execution by dynamically assimilating new workflow engines and balancing workload among these engines. Moreover dynamic load balancing is applied in DWM4CGSP in order to make workload on each engine at reasonable level. Finally an implementation demonstrates that DWM4CGSP works well in CGSP and can be further extended to other similar grids
