OpenMP并行计算例子,主要包括简单例子、并行循环、常用函数、分段并行、嵌套并行、求π以及同步这些例子。所有例子都已经过测试。-OpenMP parallel computing examples, including a simple example, a parallel loop, commonly used functions, segmented parallel nested parallelism, find π and the synchronization of these

嵌套并行，OpenMP 采用 fork-join（分叉-合并）并行执行模式。线程遇到并行构造时，就会创建由其自身及其他一些额外（可能为零个）线程组成的线程组。遇到并行构造的线程成为新组中的主线程。-Nested parallelism, OpenMP using fork-join (fork- Merge) parallel execution mode. When a thread encounters a parallel construct, it creates its own and
