Distributed Workflow Management in Open Grid Services Architecture

摘要

Vast resources in a grid can be managed flexibly and effectively by workflow management systems. Here a structure of the workflow management system in Open Grid Services Architecture is proposed. In the structure, main components of conventional workflow management systems are made into some high-level Grid Services and distributed in the grid. Then those services compose a distributed workflow management system, which can make full use of the workflow resources and ensure the process executed efficiently and reliably in the grid The interfaces required by those workflow services and some implementation details of the system are discussed too.
