Hi Farago,
I'm afraid that currently Open MPI doesn't have such feature to make
Linux and Windows work together. But the idea is still interesting. :-)
By the way, there are many configure options for windows build are still
experimental, and they may not work or work improperly.
Thanks,
Shiqing

He, this is getting annoying, but I have another question:
I am trying to get windows and linux hosts to work together. Is this
even possible with openmpi? I tried mpich2 first but there were
several problems and on google I found some hints that openmpi will do
the job. However I don't see any cross-platform run-time systems.
Obviously rsh/ssh doesn't work on Windows and neither does MS CCP on
linux.
The FAQ does state heterogeneous execution environments but I get the
feeling Windows <> Linux is not what is meant there.

Is the windows build actually working? I have the static library
version working correctly, however shared libraries give linker errors
when compiling an MPI application. It seems libmpi_cxx.lib doesn't
export any functions, only constant data members (checked through
dependency walker of libmpi_cxx.dll and dumpbin of libmpi_cxx.lib)
Eg in a very simple MPI application I get unresolved external symbols
about MPI::Datatype::Free, MPI::Win::Free, MPI::Comm::Comm and
ompi_mpi_cxx_op_intercept. I am linking to libmpi.lib and
libmpi_cxx.lib, both of which have been built with the CMake solution
where the only changes were the enabling of heterogeneous support, the
one in osc_rdma_data_move.c and setting Link Library Dependencies to
yes as per my previous mail.

Information: Windows XP SP3 x86, MSVC 2008 Professional, openmpi 1.4.1
There is a compile error if I enable heterogeneous support, see error
message below. The relevant line is:
payload= (void*)malloc(buflen);
ompi/mca/osc/rdma/osc_rdma_data_move.c(1059): error C2440: '=': cannot
convert from 'void *' to 'void **'
gcc doesn't complain, I've changed void* to void** which seems to
"fix" the problem
Also when generating the MSVC2008 project files through CMake (2.8.0)
there are linker errors for all the project files. libopen-pal.lib and
libopen-rte.lib aren't linked in with the other projects. I couldn't
fnd anything in CMake to fix this, so I manually edited each project
file to change LinkLibraryDependencies to TRUE which for some reason
is set to FALSE by CMake. The relevant option in Visual Studio is in
Configuration Properties > Linker > General > Link Library
Dependencies. I am not familiar with CMake so unfortunately I can't
offer a proper solution.
