| 摘 要： | 受到功耗和温度的限制，传统的单核处理器性能难以提升，多核计算成为新的处理器模式。然而现有的多线程程序设计是以单核处理器为基础发展而来，无法高效利用多个处理核心来提升性能。以OpenMP为基础，对程序进行多线程优化，以实现多核处理器上多线程的并行，并通过经典的N皇后问题案例进行验证。

| Abstract: | The traditional single-core processors are difficuh to be enhanced for their performance with the limitation by power dissipation and temperature. Multi-core computing has been the new mode of processor design. Designs the current multi-thread programs for single-core processors and they cannot take full advantages of the multiple processor cores to improve the performance. Proposes a novel approach to optimize the programs with multi-thread based on OpenMP. This approach can support the parallel running of multiple threads on multiple processor cores and it is verified through the typical N Queens Problem. |
