I'm searching for a detailed procedure to install MPI (such OpenMPI) under Win32 (WinXP in my case) with Boost,

Something like this? http://www.boost.org/doc/libs/1_46_1/doc/html/mpi/getting_started.html

Maybe together with some more general information from this page? http://www.boost.org/doc/libs/1_46_1/more/getting_started/windows.html

...

and some sample code to use the parallel graph algorithm.

All sample code provided by Boost developers can be found in $BOOST_ROOT/libs/library-name/example, i.e. in this case $BOOST_ROOT/libs/mpi/example (where $BOOST_ROOT is the path to the Boost root directory). If this directory doesn't contain any examples of a parallel graph algorithm, and if a Google search for "MPI graph algorithm" does not yield the kind of result you need, I'm afraid no such sample code exists.

Thanks Arpan,

I've tried to find this implementation, but I'm not be able to... where can I find it?

Thanks! I'm not able to recompile Open MPI on Win32, so I've downloaded and installed the Windows installer that I've found in http://www.open-mpi.org/software/ompi/v1.5; then I've configured the user-config.jam adding the line:

using mpi ;

So I've tried to build the boost with this command:

bjam debug release -a --toolset=msvc-10.0 stage

but it can't able to find the MPI install. The compiler message is:

MPI auto-detection failed: unknown wrapper compiler C:/Programmi/OpenMPI_v1.5.2-win32/bin/mpic++.exe Please report this error to the Boost mailing list: http://www.boost.org You will need to manually configure MPI support.

So I've tried to modify the user-config.jam in:

using mpi : C:/Programmi/OpenMPI_v1.5.2-win32/bin/mpic++.exe ;

But the error is the same.

The Boost.MPI getting started page also metions these steps:

If your MPI implementation does not have a wrapper compiler, or the MPI auto-detection code does not work with your MPI's wrapper compiler, you can pass MPI-related options explicitly via the second parameter to the mpi module:

...

using mpi : : <find-shared-library>lammpio <find-shared-library>lammpi++ <find-shared-library>mpi <find-shared-library>lam <find-shared-library>dl ;

To see the results of MPI auto-detection, pass --debug-configuration on the bjam command line.

Did you try those? -Julian

Yes, I've tried the follow 2 config (separately):

1) using mpi : : <find-shared-library>mpic++ ;

2) using mpi : : <find-shared-library>lammpio <find-shared-library>lammpi++ <find-shared-library>mpi <find-shared-library>lam <find-shared-library>dl ;

But they both fail, it seems not be able to find some Open MPI includes.

2) is taken directly from the example on the Boost.MPI website, right? But that's just an example, for the case when you're using LAM/MPI. It won't work in your case because you're using Open MPI. It will probably look more like this: using mpi : : <find-shared-library>openmpio <find-shared-library>openmpi++ <find-shared-library>mpi ; You'll have to consult the Open MPI documentation to find out what exactly to fill out there.

Is there a place where I must specify the Open MPI include path?

I'm not very familiar with MPI compiler wrappers (or with MPI in general, so if anyone more informed can help please do so), but if your MPI headers are not in your CPPPATH then yes, you should probably specify the Open MPI include path in your Jamfile. Like this: project : requirements <include>C:/wherever/you/put/openMPI ; You can find the entire Boost.Build documentation here: http://www.boost.org/boost-build2/doc/html/index.html HTH, Julian
