摘　　要：目前,随着大规模并行计算的高速发展,并行程序性能分析与建模的地位日益重要,而并行程序性能数据的采集是进行性能分析的基础。硬件计数器的使用使人们能够更加便利地在程序执行过程中采集性能数据。文章讨论了OpenMP并行程序的性能数据采集技术,并介绍一种利用PAPI进行数据采集的实现方法。Nowadays, performance analysis and profiling for parallel programs are quite critical with the development of large scale parallel computing, and performance data collecting is the basis of this job. Using of hardware performance counters facilitates the collecting of performance data during execution of a program. This paper focuses on performance data collecting of OpenMP parallel programs, and presents an outline of the implementation making use of PAPI.
