Hi,
The code works for me under MinGW console with the pre-compiled
installer. Could you try "which mpicc" to ensure that the correct Open
MPI commands are in path?
For building Open MPI by your self with CMake, you have to configure it
in the GUI and then generate the sln files by pressing the generate
button. I don't recommend to use the other two means, they haven't been
tested for some while.

hi,
the following code:
int main(int argc, char **argv)
{
int procnum;
/* Initialize MPI */
MPI_Init(&argc, &argv);
/* Find out this processor number */
MPI_Comm_rank(MPI_COMM_WORLD, &procnum);
/* Find out the number of processors */
std::cout << "I'm process: " << procnum << std::endl;
MPI_Finalize();
return 0;
}
also goes with the same rank "0" error, I think if there's something
wrong with the auxiliary program "mpirun" ?
BTW, I tried all the 3 means on your
http://svn.open-mpi.org/svn/ompi/trunk/README.WINDOWS.txt guideline
but none worked to compile my own dll for
http://www.open-mpi.org/software/ompi/v1.4/downloads/openmpi-1.4.3.tar.bz2,
the first approach failed because I found no .sln file in the
distributed tarballs after configuring with cmake, the second mean I
can not use is the lacking of ompi-static.tgz file, the 3rd solution I
tried does not work neither, because I don't know what the ash.exe
shell interpreter you are actually pointing to, so I'd be much
appreciated if you can tell me the a working approach. Thanks very much.

Hi,
I've never tried this Boost.MPI with Open MPI on Windows. Does it
work without the Boost.MPI library? Did you run your test under MinGW?

Run time environment of mine is Windows 7, with the unstable
OpenMPI_v1.5.3-2_win32.exe
<http://www.open-mpi.org/software/ompi/v1.5/downloads/OpenMPI_v1.5.3-2_win32.exe>
release
for Windows, together with Microsoft Compute Cluster Pack.
Additionally I'm using Boost.MPI library v1.47 compiled by mingw,
I write those following codes:
int main(int argc, char **argv)
{
mpi::environment env(argc, argv); // Boost.MPI class
boost::mpi::communicator worldCom; // Boost.MPI class
std::cout << "rank():" << worldCom.rank() << std::endl;
worldCom.barrier();
return 0;
}
and successfully compiled and linked with your library as "a.exe"
by mingw, however, if I run it:
>mpirun -np 4 a.exe
the command will create 4 process with the same rank "0", I
wonder if it's the bug of your unstable release for windows?
BTW, can you publish the Visual studio project to the subversion?
Thanks very much.
