摘要
描述了CC-NUMA模拟环境——AMY的研究与实现。它采用多项优化技术,能在X86 PC机上的Linux操作系统环境下运行,能够较精确地统计并行程序的时间开销和CC-NUMA并行系统的各项参数,它特别适合于分析并行程序在CC-NUMA系统下的执行行为和开销,能够有效指导并行程序的优化和对CC-NUMA并行系统进行深入研究。最后将AMY模拟环境与CC-NUMA系统以及其它的模拟环境进行比较分析,对它的精确性、灵活性和有效性进行了检验。
According to the characteristics of CC-NUMA systems, this paper presents the research and implementation of CC-NUMA simulating environment-AMY. AMY adopts many optimization technologies and executes on Linux operating system in X86 PC. It can state the time overhead of parallel programs and many statistic parameters accurately. It is suitable to analyze the executing behaviors and overhead of parallel programs in CC-NUMA systems in order to direct optimization of parallel programs and to study CC-NUMA systems. Through experimentation on AMY, this paper is compared with CC-NUMA parallel systems and other simulators so as to verify its accuracy, agility and validity.
