This paper describes the design and implementation of CampusWare, a lightweight grid middleware for the compute-intensive applications in campus environment. Though there are many grid middlewares available, they are unnecessarily complex for use in the campus environment where the main applications are compute-intensive, and the main requirements are the convenience and efficiency in clusters management and job submissions. To deal with the problem, CampusWare proposes a ldquofast jobrdquo concept and provides a two-layer middleware architecture as well as a three-layer user account hierarchy. Compared with the existing grid middlewares, its deployment, configuration and usage are all simplified, which makes it easy-to-use, efficient and portable.
