You don't need to check anything alse in the red window, OpenMPI doesn't
know it's in a virtual machine. If you're running Windows in a virtual
cluster, are you running as 32-bit or 64-bit?

Wow thanks a lot guys. I'll try it tomorrow morning. I'll admit that
this time when i saw that there are some header files "not found" i
didn't even bother going through the all process as I did previously.
Could have had it installed by today. Well i'll give it a try tomorrow
and come back to you with a confirmation of whether it works or not.
For the "virtual cluster", should I select check any of the checkboxes
in the red window?
Either way, thanks a lot guys, you've been of great help to me. I
really want to do my project well, as not many almost-18 year olds get
to work with clusters and I'd like to take full advantage of the
experience

Alex,
That red window is what you should see after the first Configure
step in CMake. You need to do the next few steps in CMake and
Visual Studio to get a Windows OpenMPI build done. That's how
CMake works. It's complicated because CMake has to be able to
build on multiple OSes so what you do on each OS is different.
Here's what to do:
As part of your original CMake setup, it will have asked you where
to put the CMake binaries. That's in "Where to build the
binaries" line in the main CMake window, at the top. Note that
these binaries aren't the OpenMPI binaries, they're the Visual
Studio project files that Visual Studio uses to build the OpenMPI
binaries.
See the CMAKE_BUILD_TYPE line? It says Debug. Change Debug to
Release if you want a Release build (you probably do). Press the
Configure button again and let it run. That should be all clean.
Now press the Generate button. That will build the Visual Studio
project files for you. They'll go to the "Where to build the
binaries" directory. From here you're done with CMake.
Next you have two options. You can build from a command line, or
from within Visual Studio itself. For command-line instructions,
read this:
https://www.open-mpi.org/community/lists/users/2010/02/12013.php
Note that you need to execute the devenv commands in that post
from within a Visual Studio command prompt: Start, All Programs,
Visual Studio 2008, Visual Studio Tools, Visual Studio 2008 Win64
x64 Command Prompt. I'm assuming you want a 64-bit build. You
need to be in that "Where to build the binaries" directory as well.
To use Visual Studio directly, start Visual Studio, and open the
OpenMPI.sln project file that's in your "Where to build the
binaries" directory. In the Solution Explorer you'll see a list
of sub-projects. Right-click the top heading: Solution 'Open MPI'
and select Configuration Manager. You should get a window that
says at the top Active Solution Configuration, with Release below
it. If it says Debug, just change that to Release and it will
flip all the sub-projects over as well. Note on the the list of
projects the INSTALL project will not be checked. Check that now
and close the window. Now right-click Solution 'Open MPI' again
and hit Build Solution. It takes a while to compile everything.
If you get errors about error code -31 and mt.exe at the end of
the build, that's your virus scanner locking the new exe/dll files
and the install project complains. Keep right-clicking and Build
Solution until it goes through. The final Open MPI include files
and binaries are in the C:\Users\Alex's\Downloads......\installed
directory.

PS OpenMPI 1.4.2 doesn't have Fortran support on Windows. You
need the dev 1.5 series for that and a Fortran compiler.

Hey,
I installed a 90 day trial of Visual Studio 2008, and I am
pretty sure I am getting the exact same thing. The log and the
picture are attached just as last time. Any new ideas?
Regards,
Alex
