摘要
首先给出基于用户实例分析的网格可靠性分析模型,通过分析应用遥感图像处理典型实例来分析图像处理网格的可靠性;然后实现了基于错误注入的图像网格组件可靠性评测环境,按照组件吞吐率来评价网格中间件组件的错误容忍能力;最后根据模拟仿真环境的试验数据构建组件依赖图,在组件依赖图的基础上分析了ChinaGrid图像处理网格各组件对于图像处理应用的可靠性的影响,并给出了图像网格开发和部署建议.另外根据错误注入的方式评测了图像处理网格核心组件即网格容器的可靠性.
A model to analyze grid reliability was proposed after user＇s practice was studied, the grid reliability in image processing was analyzed. Based on fault injection, a grid component reliability evaluation environment was implemented, which tested the component reliability by comparing the component throughput between with non-fault workload and with fault load. Based on the reliability analysis model, the reliability relationships between the image processing application and every key component of the image grid middleware were analyzed. With the reliability evaluation environment, the reliability of the container of the image grid was evaluated over a cluster. Based on the analysis and evaluation, the suggestion for software development and software deployment was proposed.
