I'm using Boost 1.46.0 with OpenMPI 1.5.3 under Gentoo x64. I have compiled OpenMPI with thread and mpithread option and Boost with MPI support. A little testprogram with:

#include namespace mpi = boost::mpi;

int main(int argc, char* argv[]) { mpi::environment loMPIenv(argc, argv); mpi::communicator loMPICom;

return 0; }

crashes alway if I run it with "mpiexec -np" (without mpiexec it runs).

I've tested your program with:

* OpenMPI 1.4.1 (from the Ubuntu 10.10 package `libopenmpi-dev` version 1.4.1-3ubuntu1), Boost 1.46.0 (compiled by myself) on Ubuntu 10.10 64-bit with the GCC 4.4.3 compiler;

* OpenMPI 1.4.3a1r23323, Boost 1.45.0 (both compiled by myself) on Rocks 5.2 64-bit with the GCC 4.1.2 compiler;

In either case, the program runs correctly, whatever the number I write after "mpirun -np".

I'd check whether there is any compilation mismatch between OMPI and Boost, check again threads support, etc.

I've tested it again. I recompiled my OpenMPI with thread, but not with "mpithread" support. The compile flags are now: cxx threads -elibc_FreeBSD -fortran -heterogeneous -ipv6 -mpi-threads - pbs -romio -vt (- disable the feature). The code works, so I think the "mpi-threads" option makes the problem Best regards Phil
