| Abstract: | 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. |
