Parallel processing 如何在OpenMP中的单线程块内声明共享工作区域？

我正在尝试使用OpenMP为具有以下方案的函数编写并行代码：

1. Begin of data-dependent loop
    2. Some computation
    3. If the result of 2 equals 0 then
        3.1. Begin of data-independent loop
        3.2. Some computation
        3.3. End of data-independent loop
    4. Some computation by a single thread
    5. Begin of data-independent loop
        6. Some computation
    7. End of data-independent loop
8. End of data-dependent loop    

问题是-我想用以下内容将这些区域括起来：

#pragma omp parallel
1. Begin of data-dependent loop
    #pragma omp master
    2. Some computation by a single thread
    3. If the result of 2 equals 0 then
        #pragma omp for
        3.1. Begin of data-independent loop
        3.2. Some computation
        3.3. End of data-independent loop
    4. Some computation by a single thread
    #pragma omp for
    5. Begin of data-independent loop
        6. Some computation
    7. End of data-independent loop
8. End of data-dependent loop

但是，编译器不允许将

pragma omp for

嵌套在

pragma omp master

中。除了将它们更改为

pragma omp parallel for

并放弃主循环外的fork之外，还有什么解决方案吗

如果不够清楚，请告诉我

提前感谢

是的，只需像这样并行化内部循环

for(int i=0; i<n; i++) {
   cut = foo(i);
   if(!cut) {
       #pragma omp parallel for
       for(int j=0; j<m; j++) {
           //
       }
   }
   foo2();
   #pragma omp parallel for
   for(int j=0; j<k; j++) {
       //
   }
}

for（int i=0；i将主控变量仅限于2。没有真正的代码，很难更精确。
