| Abstract: | The emergence of the parallel program has greatly increased the application execution efficiency, multi-coreprogram design needs to consider the performance of the program. This article focuses on OpenMP multi-core multi-hread program in the programming model in parallelization overhead, load balancing, thread synchronization overhead aspects effect the performance of the program. |
