A Client-Side Workflow Middleware in the Grid

Grid computing is becoming a mainstream technology for sharing large-scale resources, accomplishing collaborative tasks and integrating distributed systems. With the development of the Grid technology, the Grid will provide the fundamental infrastructure not only for e-Science but also for e-Business, e-Government and e-Life. The workflow management system in the Grid is important to support such Grid applications. This paper proposes a framework of client-side workflow middleware, puts the emphasis on the transaction management and service discovery in workflow. The transaction in the workflow includes atomic transaction and compensation transaction. The coordination of these transactions in workflow is introduced in detail.
