RESEARCH AND IMPLEMENTATION OF A SIMULATING ENVIRONMENT FOR CC-NUMA PARALLEL SYSTEM

摘要

CC-NUMA parallel system gradually becomes one of the mainstream technologies in super-computing areas at present. 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, and it has high executing speed and costs less memory. 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 real CC-NUMA parallel systems and other simulators so as to verify its accuracy, agility and effectiveness.
