Research on Scheduling Algorithm for Workflow-Based Grid Resource

In the research area of grid computing and workflow technology, workflow products based on Web-service technology can work as grid services in grid architecture. A new algorithm of scheduling grid resource with workflow engine is discussed in this paper. The QoS, executing time of process, cost and workload of grid resources are the key factors in grid resources scheduling. Dynamic feed back mechanism and executing time estimation are applied in this algorithm, which can keep the grid resources in a good balance and advance the whole performance of the grid application with workflow service.
