【摘要】 网格利用互联网将分散在不同地理位置的计算机整合成一台“虚拟超级计算机”,以便实现资源的全面共享和协同。如何实时准确地监控与发现网格中资源的状态和配置情况是网格的一个关键技术。目前的网格资源监控与发现系统难以适应全局网格的分布性、可缩放性、异构性等特点。P2P技术是开发分布式系统的一种有效方法,将P2P技术与网格技术相结合是一条解决网格资源监控与发现问题的有效途径。本文首先对网格及网格资源监控与发现系统的特点做了详细的介绍,分析了当前国内外在该领域的研究现状;然后在对P2P技术研究分析的基础上,提出了一种基于P2P技术的网格资源监控与发现系统模型。此模型能够充分适应网格环境的特点,既保证了网格监控与发现系统的准确性和高效性,又具有良好的可扩展性。文章最后给出了此模型的性能评价,并就存在的问题与下一步的工作进行了展望。更多还原

【Abstract】 Grid combines the computers located at different locations into a "visual super-computer" via Internet, and intends to realize the overall comprehensive sharing and collaboration of resources. It is a vital technique in grid that how to monitor and discovery these resources. Nowadays, GRMAD(Grid Resource Monitor And Discovery) system is difficult to fit totally to the distribution, scalability and heterogeneousnes of the grid. P2P technique is a fruitful method for developing distributed system, which can provide an ideal approach to solve problems in GRMAD. In this paper, the characteristic of grid and GRMAD system are introduced in detail; Then, analysis is given to research status at home and abroad; After doing lots of research of P2P network, a GRMAD system model based on P2P technique is put forward. The system model can adapt well to the grid environment, and it has the characteristics of veracity, efficiency and expansibility. At last, performance analysis on the model is given, and some existing questions and further research work are proposed.更多还原
