网格模拟环境中统计分析技术研究

在对现有的典型网格模拟系统的统计分析功能进行分析比较的基础上,提出了一种包括数据的获取、统计和分析的方法,并且在网格模拟系统JFreeSim中加以实现.该方法针对网格模拟器中性能分析问题,在稳态模拟条件下,根据统计分析实体对其他各个实体的监控信息,制定统计量,并依据制定的评价指标和算法对统计量进行了分析比较,给出了比较结果.该方法通过给出可能存在的性能瓶颈,为分析各种不同的场景下网格系统及算法的性能和可扩展性提供了有效手段.

Research on statistical and analyzing technology in grid simulation environment

The emergence of the grid simulator has provided researchers with a great amount of convenience.In this paper,we first analyze and compare the statistics and analyze part of several typical grid simulators,and then propose our own way of doing data statistics and analyzing that includes data collecting,doing statistics and analyzing,and describe how it works in JFreeSim.In JFreeSim,based on the monitoring information of each entity,we first propose several metrics,then analyze these metrics in accord with certain evaluation algorithm,and finally demonstrate the result to the user.The idea is to provide researchers with an efficient means to analyze the performance and scalability of the simulated grid system and algorithm under various scenarios by offering the possible performance bottleneck.
