Subject: Re: [OMPI users] Anyone with Visual Studio + MPI Experience

Hi,

well, I don't have a lot of experience with VS+MPI, but these are the
steps taht I followed to make my projects run:

1. Select your project from the Solution explorer, right-click and select
"Properties"

2. From the list on the left, select "Debugging"

3. Set "Debugger to launch" to "MPI Cluster Debugger"

4. Set "MPIRun Command" to the full path of your "mpiexec" (use quotes at
to enclose the path)

5. Use "MPIRun Arguments" to set the number of processes to start, like
"-n 4"

6. Set "MPIRUN Working Directory" if you need.

7. "Application Command" normaly is "$(TargetPath)"

8. "Application Arguments" if you need them.

9. "MPIShim Location", this is a triky one, for some reason some times VS
needs the full path for this VS tool. It is located at: "C:\Program
Files\Microsoft Visual Studio 9.0\Common7\IDE\Remote
Debugger\x64\mpishim.exe" or "C:\Program Files\Microsoft Visual Studio
9.0\Common7\IDE\Remote Debugger\x86\mpishim.exe" (use quotes at to enclose
the path).

I haven't played with the other options.

10. Close the dialog box.

11. Set some breakpoints in your program.

12. Ready to run.

These instructions only work to debug MPI processes on the localhost, and
I only have tested VS+MPI using MPICH2 for Windows.

To debug on several nodes you should install the Microsoft HPC SDK (I
haven't used it).

Good luck.

-Miguel

PS. I use Visual Studio 2008 professional. Also, I know that MPI debugging
is not available in VS Express editions.
