for (int i = 0; i < n; i++) { // 循环体代码 } ``` 2. 使用`omp for`指令的`collapse`子句:`collapse`子句允许将多个嵌套循环合并为单个并行循环。通过指定`collapse(n)`,将会并行执行`n`个循环。例如: ```c++ #pragma omp parallel for collapse(2) for (int i = 0; i < n; i++)...
#pragma omp parallel forfor(int y=0; y<25;++y){#pragma omp for // ERROR, nesting like this is not allowed. for(int x=0; x<80;++x) { tick(x,y); }}123456789 1. 在OpenMP 3.0中,可以利用collapse指令来解决循环嵌套问题,如: #pragma omp parallel for collapse(2)for(int y=0; y<...
