摘　　要：网格技术的发展对网格系统的效率和服务质量提出了更高要求 在综合研究目前网格作业调度环境的基础上 ,提出一种容错计算网格作业调度的随机Petri网模型 ,并给出了网格作业分派策略和计算站点内的作业选择策略 ,以及容错计算网格的性能评价指标 仿真实验对容错计算网格的性能进行有效的分析 。With the development of grid technology, higher requirements are imposed on the efficiency and quality of the grid system. In this paper, the existing grid-scheduling environment is analyzed and a novel grid-scheduling model is put forward based on fault tolerance of stochastic Petri net. Grid job dispatch policy, job selection policy in computational site and performance metrics in computational grid are also discussed. The performance of computational grid based on fault tolerance is analyzed by software emulation. The numerical results show the effect on different type of jobs.
