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.

Best regards,
Riccardo
