我尝试在openmp中运行调度示例，但它的工作顺序。
omp_set_num_threads(4);
#pragma omp parallel for schedule(static, 3)
for (int i = 0; i < 20; i++)
{
printf("Thread %d is running number %dn", omp_get_thread_num(), i);
}
结果:
Thread 0 is running number 0
Thread 0 is running number 1
Thread 0 is running number 2
Thread 0 is running number 3
Thread 0 is running number 4
Thread 0 is running number 5
Thread 0 is running number 6
Thread 0 is running number 7
Thread 0 is running number 8
Thread 0 is running number 9
Thread 0 is running number 10
Thread 0 is running number 11
Thread 0 is running number 12
Thread 0 is running number 13
Thread 0 is running number 14
Thread 0 is running number 15
Thread 0 is running number 16
Thread 0 is running number 17
Thread 0 is running number 18
Thread 0 is running number 19
如何让代码并行工作?
我使用的是Microsoft Visual Studio 2017。
在Microsoft Visual Studio中，OpenMP支持是默认禁用的。您可以使用/openmp编译器选项启用它。
该选项可以在项目属性C/C++->Language→Open MP Support.
