OpenMP 同步共享变量读写单一文件 I/O OpenMP 提共下列同步结构 : – atomic – critical section – barrier – flush – ordered – single – master 这两个结构实质上不属于同步结构 , 是并行区结构和任务分割结构中的内容 . 2006 年 4 月共享存储编程 80/108
critical section 同时至多有一个线程进入临界区 . #pragma omp critical [(name)] new-line structured-block C$OMP PARALLEL DO PRIVATE(B) C$OMP& SHARED(RES) DO 100 I=1,NITERS B = DOIT(I) C$OMP CRITICAL CALL CONSUME (B, RES) C$OMP END CRITICAL 100 CONTINUE 2006 年 4 月共享存储编程 81/108
