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.

this paper verifies the assurance required of highly reliable, low cost, highly functional and highperformance space on-board computers that use commercial parts, and proposes an architecture and technology that realize the necessary assurance. With such technology, the on-board computer attains not only fault tolerance but also high versatility, that allows it to be applied to any space vehicle and space application as well as enabling easy testing and verification. this is demonstrated through a functional verification test and radiation test using a breadboard model (BBM).

As the Internet is evolving away from providing simple connectivity towards providing more sophisticated services, it is difficult to provide efficient delivery of high-demand services to end-users due to the dynamic sharing of the network and connected servers. To address this problem, we propose the service grid architecturethat incorporates dynamic replication and deletion of services.
the issue of providing efficient media retrieval services has been an important problem in recent years. Among them, video-on-demand (VoD) is one of the most popular and challenging ones. An efficient solution to the ...
