There are other compilers available as well - both Intel C/C++ Compiler (commercial license required) and GCC (freely available) support newer OpenMP versions and other compilers are available too.

See here for more information on how to use OpenMP in Visual Studio. Unfortunately its OpenMP support is a bit outdated - even the latest and greatest Visual Studio only supports OpenMP 2.0 (an outdated standard version from 2002). The standard compiler for Windows comes from Microsoft and it is the Microsoft Visual C/C++ compiler from Visual Studio. You just need a decent compiler that supports OpenMP and you need to know how to enable OpenMP support since it is usually disabled by default.

This entry was posted by admin on Jat 11:06 pm under OpenMP. Try adding this into the environment variables: “OMP_NUM_THREADS=4”, and see if your program now spawns with four threads. There is a field called “Environment”, which is where we can set environment variables.
In the left-hand column, select “Debugging”. To change this behavior, right-click on your project in the Solution Explorer window, and select properties. However, if you have a single-core computer, only one thread will be created for your program. By default, Visual studio should detect the total number of processors available in your computer, and start your program with said number of threads. Therefor, if you only see your program print this statement once, that means your program is only running on one thread. If you look at the source code, you can see that the program should print, “Running on multiple threads”, once for each thread. Troubleshooting: Changing the number of threads

Step 4: Try out your program and see if it runs on multiple threadsįor this step, you’ll want to download the source code here. Visual Studio will already know the location, so all you have to do is type “#include ” at the top of your source code. While you may not need it right away, it’s a good idea to go ahead and include omp.h in your source code. Click ok, and make sure your application still compiles and runs. Select C/C++ -> Language, and change “OpenMP Support” to ‘Yes’. Right-click on your project, and select properties. However, that means that it’s very complicated for the compiler to handle OpenMP.
OpenMP does a lot of things automatically for us programmers. On the next dialog, click application settings, then clear the checkbox next to “Precompiled Header”.
If you select Visual C++ -> Win32, you should see the Console Application as an option. For this tutorial, we will be creating a Win32 Console Application. The simplest way to test your first OpenMP program would be to create a new project.

For this tutorial, I will be using Visual Studio 2005 professional edition, however, this tutorial will apply to almost all recent versions of Visual Studio. There might be a way to work around this limitation by trying to download vcomp.lib or vcomp.dll, however, the legality of doing that is questionable. Therefore, you will need the professional version or higher if you want to use visual studio to develop OpenMP project. First things first, OpenMP is not available for the express or standard versions of Microsoft Visual Studio. Welcome to my tutorial on how to get started with writing OpenMP applications in Visual Studio.
