MPI with MinGW and Eclipse

Question

My question is devided in two parts :

1. What is the best combination to execute MPI program in C language, when i searched for the necessary tools i found who work with Visual Studio and MS-MPI , and who work with Eclipse PTP or Code::Blocks and MPICH2 MPIOpen so i didn't know what to choose and what are tools that are compatible which other?

2. So ive installed OpenMPI,Eclipse PTP (Kepler) and MinGW-w64 to compile some C programs using MPI on windows 7 64Bits. i set all paths such as mpicc.exe i tried to test the Hello world program which is include with eclipse as example, i got this error:

   13:03:48 **** Incremental Build of configuration Debug for project A **** Info: Internal Builder is used for build

   mpicc "-IC:\Program" Files "(x86)\OpenMPI_v1.6.2-x64\include" -O0 -g3 -Wall -c -fmessage-length=0 -o "src\A.o" "..\src\A.c"

The Open MPI wrapper compiler was unable to find the specified compiler cl.exe in your PATH.

Note that this compiler was either specified at configure time or in

one of several possible environment variables.

13:03:48 Build Finished (took 115ms)

So i searched for cl.exe in my computer but i didn't found it, when i looked for some solution i found that the majority who solved this cl.exe problem are using visual studio, which is not my case so am little bit confused i dont want to switch to Visual Studio, so any solution with the tools that am using ?

Answer 1

OpenMPI does not appear to officially support MinGW as a backend: https://www.open-mpi.org/software/ompi/v1.6/ms-windows.php

The installers were configured with CMake 2.8.1 and compiled under Visual Studio 2010, and they support for C/C++ compilers of Visual Studio 2005, 2008 and 2010.

https://www.math.ucla.edu/~wotaoyin/windows_coding.html and other sources found on a search describe workflows using MS-MPI with MinGW. It may be a viable alternative. VSCode and MPI in WSL describes yet another non-paid but proprietary approach using VSCode with the WSL plugin.
