| Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 95 === As computation, storage, and communication technologies steadily improved, application developers and users are planning increasingly large runs that will operate on and generate petabytes of data. Although microprocessors are reaching impressive speeds, in the long run they are falling behind storage. Fortunately, improvements in wide-area networking make it possible to aggregate distributed resources in various collaborating institutions and to form what have come to be known as Computational Grids. Recently, Grid computing has been identified as a critical technology by industry for enterprise computing and business-to-business computing.
Web Services Based Computing Power Service (WS-CPS) is a distributed computing system built for small and middle-sized enterprise. It combines Web Services and Oracle BPEL Services for providing a visualized developing environment and workflow management. However, there are unsolved issues in WS-CPS. Therefore, in this article, we proposed a NaradaBrokering Based Computing Power Service (NB-CPS), which is not only suitable for executing computing works which are able to run in batch, but also be able to solve current issues in WS-CPS such as system resilience, fault tolerance, efficiency of job scheduling and the instability in congested network environment.
