→Case A - Using the Thread window
==Case A - Using the Thread window==
The following example of how to use Visual Studio's thread window was performed on Microsoft Visual Studio 2019 with Intel OneAPI Libraries and Intel Visual C++ Compiler.
<syntaxhighlight lang="cpp">
#include <iostream>
#include <omp.h>
using namespace std;
int main()
{
printf("num of default usable thread is %d \n\n", omp_get_max_threads());
// serial ver
printf("num of thread currently using is %d \n", omp_get_num_threads());
printf("working thread num is %d \n", omp_get_thread_num());
printf("\n");
#pragma omp parallel
{
#pragma omp single // set openMP ver
{
printf("num of thread currently using is %d \n", omp_get_num_threads());
}
printf("working thread num is %d \n", omp_get_thread_num());
}
printf("\n");
#pragma omp parallel num_threads(8)
{
#pragma omp single // set openMP with num of threads ver
{
printf("num of thread currently using is %d \n", omp_get_num_threads());
}
printf("working thread num is %d \n", omp_get_thread_num());
}
printf("\n");
return 0;
}
</syntaxhighlight>
