People can get all kinds of information from Internet through Web browsers. This trend has a great impact on our computing environments. Computations need not be confined to local machines any longer. They may be stretched across multiple machines over the Internet. Therefore, how to model cooperative computing and take advantage of the computing power spread across the Internet has become a very important problem. 　　In this thesis, we propose a Web-enable cluster computing system. The system allows cluster-based computation resources to be shared by users all over the world through WWW. The Web-enable cluster computing system contains five components: a server Web interface, a Java PVM platform, an AOV-aware execution facility, a matrix package and a load balancer. The server Web interface with users to load their Java programs, sets up the desired execution environment, compiles the source code and distributes the executable image to other computers in the cluster. The Java PVM platform supports low-level communication between java processes and presents to the user Java programs a virtual distributed-memory multiprocessor on top of the cluster. Our cluster environment provides supports to facilitate the programming of systems representable in activity-on-vertex networks, It makes communication between processes in the AOV network easy. A matrix package is provided to improve the performance of matrix operations by taking advantage of cluster computing. Finally, the load balancer balances the load in the cluster by dispatching tasks to lightly-loaded computers. 　　A possible use of such a Web-enabled cluster computing environment is in organizations such as supercomputer centers in which users submit their jobs through the Internet and run their programs over the various computers, often concurrently, in the center. In this way, computing resources may be shared more efficiently. In addition, through Internet and Web-based browsers, the computing resources may be accessed more easily from remote even without user login first. 　　In this thesis, we will introduce the concept and discuss the issues involved in developing a Web-enabled cluster computing environment, and describe the implementation of such an environment. Its usage and performance will also be presented.
