OpenMP Test on Visual Studio
To use OpenMP on Visual Studio IDE, we should set in tools->options like..
Below code is to calculate pi using loop logic.
There are 5 case code.
0 case is for testing, openMP running well or not.
1 case is no treading, else 2~4 case is some different OpenMP threading case.
I am also not friendly with openMP, so I will refer this code when not remember well.
And I will add more useful technical code..
<gist>
</gist>
The result image tells us, OpenMP is certainly faster than no threading.
