The vision of Computational Grids promises an exciting future for highperformancecomputing (HPC). In this project we make a small but practical step toward the grand vision of pervasive HPC by using some of the prevailing Internet technologies to enable access of HPC anytime and anywhere. Specifically, this project focuses on HPC that could be accessed by using World Wide Web. We have conducted experiments based on engineering/scientific applications. Examples include simulations of Automated Guided Vehicles thereafter AGVs for short) in container port operations, N-body and molecular simulations. We initially build system based on an ad-hoc approach, whose merits and demerits are identified Then, we employ jini technology to reconstruct the system architecture and present a more efficient and robust model. performance studies are also presented. The objectives are to explore and address relevant issues, evaluate various approaches, demonstrate a workable version and conduct experiments with actual Web-enabled applications. The result is that now we are able to partially realize the dream of using the HPCs anytime and anywhere through devices such as a wireless/mobile computer as long as they are armed with a common Web browser.

We use the term ubiquitous supercomputing to refer to systems that integrate low and mid range computing systems, advanced networks, and remote high end computers with the goal of enhancing the computational power accessible from local environments. Such systems promise to enable new applications in areas as diverse as smart instruments and collaborative environments. However, they also demand tools for transporting code between computers and for establishing flexible, dynamic communication structures. We propose that these requirements be satisfied by enhancing the java programming language with global pointer and remote service request mechanisms from a communication library called Nexus. java supports transportable code; Nexus provides communication support. We explain how this Nexusjava library is implemented and illustrate its use with examples.
