I am a computer science student and this season we have a course in MPI programming in C language. I don't have enough hard disk space to install visual studio on my computer and I have installed codeblocks, and MinGW as compiler, and I also installed Microsoft MPI to run mpi .exe code. Now I think that I need to install Open mpi to compile my code to exe and run it using MSMPI. Please correct me if I'm wrong until now :)
In OpenMPI download page we just have binary codes, and I don't know how to install binary code in windows...
Thanks all

To use MPI with Windows, you will need to install the free download of Microsoft MPI. Go to the installation page and download MSMpiSetup.exe . Once downloaded, run the executable and follow the instructions.
./configure --prefix=/usr/local With the -- prefix option given, OpenMPI binaries are installed in the directory /usr/local/bin and shared libraries in /usr/local/lib. If you want a different installation location, replace /usr/local with your desired directory.
With OpenMPI, the easiest thing to do is to run ompi_info ; the first few lines will give you the information you want. In your own code, if you don't mind something OpenMPI specific, you can look at use OMPI_MAJOR_VERSION , OMPI_MINOR_VERSION , and OMPI_RELEASE_VERSION in mpi. h.
Microsoft MPI (MS-MPI) is a Microsoft implementation of the Message Passing Interface standard for developing and running parallel applications on the Windows platform. MS-MPI offers several benefits: Ease of porting existing code that uses MPICH.
If you plan to build your code with Open MPI and then run it with Microsoft MPI, then just drop that idea !
MPI is standard in a sense that a code can be built with any MPI implementation. There is no guarantee a binary can be ran with any MPI implementation.
Open MPI is not supported under windows, but you can use cygwin and install the openmpi packages. Linux subsystem for Ubuntu is an option i never tried but that might work too.
