openMPI 1.6.4 Experimental Windows Build

So I was browsing the openMPI website the other day on the quest to download the latest version so that I could start off with some of my video tutorials. I was slightly (actually more than slightly) disappointed to see that they are dropping support for Windows entirely since they no longer have anyone to maintain a Windows build. If I had the time I would offer it.

Anyway – I thought I would take a crack at building a windows version of 1.6.4. It required a bit of tweaking – the odd change in the code – but long story short: I got it working. I have made it available for download.

Just a quick reminder: It is an unofficial build. I have not gotten around to figuring out how to run the openMPI tests against it yet. I have tested to see if basic openMPI programs work and there seems to be no problems there. There is also no CCP support in this build.

Depending on how much time I have – I shall release a 64 bit version soon as well.


    • I did use CMake to generate the Visual Studio project files. From that point onwards you should be able to build it in Visual Studio – but as mentioned in the my post, they are no longer maintaining the Windows build, which is why I had to change the code for Windows compatibility myself. My downloads page has the built binaries for you.

  1. Do you still have the change you made to compile a 32 bit version,
    I am thinking about be a maintainer of this build. So I would like to
    pickup on your work. No need to recreate the wheel. Hopefully!
