  1. 同济大学 TONGJI UNIVERSITY 传统排序算法的并行实现

  2. 并行计算

  3. openmp OpenMP（Open Multi-Processing）是由OpenMP Architecture Review Board牵头提出的，并已被广泛接受的，用于共享内存并行系统的多线程程序设计的一套指导性注释（Compiler Directive）。OpenMP支持的编程语言包括C语言、C++和Fortran；而支持OpenMP的编译器包括Sun Studio和Intel Compiler，以及开放源码的GCC和Open64编译器。OpenMP提供了对并行算法的高层的抽象描述，程序员通过在源代码中加入专用的pragma来指明自己的意图，由此编译器可以自动将程序进行并行化，并在必要之处加入同步互斥以及通信。

  4. openmp • #pragma omp parallel for • #pragma omp parallel if • #pragma omp parallel sections • #pragma omp parallel single • #pragma omp parallel master

  5. 传统的排序算法 冒泡排序 快速排序 归并排序

  6. 并行冒泡排序 奇偶排序

  7. 并行快速/归并排序

  8. 测试结果

  9. 同济大学 TONGJI UNIVERSITY 谢谢
