一个基于OGSA规范的网格计算过程表示模型

Presentation Model of Grid Computing Process Based on OGSA

提出一个基于网格服务树的网格计算过程的表示模型。对网格服务、网格计算过程、网格服务树、网格给出了形式化的定义,描述了一个网格计算过程表示模型,并给出了实现的机制和算法,最后给出利用 Web service 技术的模拟试验的方法。分析和实验结果表明,该模型有效地表示了基于 WAN 或 Internet 的网格计算过程,符合 OGSA 规范。该模型适合网格系统的构建、监测以及基于 Web service 机制的 Internet 的 QoS 管理等应用领域。

A presentation model of the grid computing process based on grid service tree was discussed in this paper. A set of formal definitions,such as the grid service, the grid computing process, the grid service tree and the grid ,was given. The formal presentation model about the grid computing process was provided. The implementing parallel algorithms of this model were studied. The analysis and experiment result show that this model effectively presents the grid computing process on WAN or Internet, and it is according with OGS/L This model can be fit for monitoring and building the grid system and managing QoS of Internet based on Web service.
