I am trying to install Open MPI for Windows 8.1 and when I searched for it I got instructions for installing it on Windows XP & 7, but not for Windows 8.1.

A question like this was asked in stackoverflow a year ago: Installing MPI for Windows, but the question was not clear so it did not got any answers.

I also installed MS-MPI, but when I want to compile a simple cC++ file, Visual Studio 2013 doesn't recognize #include < mpi.h >.

Can anyone help me?

  • Installing on Windows 8.1 should be not much different than installing on Windows 7. For MS MPI, you should add the path to the library header files and the path to the import library in the project settings. – Hristo Iliev May 06 '15 at 12:23
  • how should i add this path? where to add it, what exactly i should add? – Shahriar.M May 06 '15 at 13:07
  • You might be able to find an MS-MPI user who can help you here, but I haven't seen any so far. You might have better luck on the MS-MPI forums: https://social.microsoft.com/Forums/en-US/home?forum=windowshpcmpi. On a related note, I'm pretty sure the Open MPI doesn't support Windows and hasn't for a long time. – Wesley Bland May 06 '15 at 14:40
  • Thank you for editing, If the Open MPI doesnt support Windows then what is MS-MPI for? – Shahriar.M May 06 '15 at 19:44
  • MS-MPI and intel mpi provide supported windows-based implementations of MPI. – Rob Latham May 06 '15 at 20:40
  • Each is a different implementation of the MPI Standard. They don't depend on each other and most of the time having multiple installations will conflict and cause problems if you're not careful. – Wesley Bland May 06 '15 at 22:15
  • Open MPI 1.6 was the last Open MPI branch supported on Windows. Their Windows maintainer left some time ago and thereafter the newer versions are only supported on Unix-like systems. – Hristo Iliev May 07 '15 at 07:16
  • You should do something like this: First you have to install Microsoft Visual Studio 2012 , Then you should download : https://www.microsoft.com/en-us/download/details.aspx?id=36044 . and install it , Then download : https://www.microsoft.com/en-us/download/details.aspx?id=44990 . and install if after Hpc Client. Then you should add a system variable with name : "anything" , and path: "Bin folder of directory that yo installed Hpc like 'C:\Program Files\Microsoft HPC Pack 2012\Bin ' ". – Shahriar.M May 08 '15 at 18:38
