You are right, that was what I was missing. Thank you. Anyway, no I can 
compile it and run it, but the program always exits at the line Graph 
g(4) with exit code 0x1. It quits in the inizialization of
mpi_process_group::impl::impl(std::size_t num_headers, std::size_t 
buffer_sz, communicator_type parent_comm)
  : comm(parent_comm, boost::mpi::comm_duplicate),
    oob_reply_comm(parent_comm, boost::mpi::comm_duplicate),
    allocated_tags(boost::mpi::environment::max_tag())

exactly in libs/mpi/src/communicator.cpp 
communicator::communicator(const ...) on the line  
BOOST_MPI_CHECK_RESULT(MPI_Comm_dup, (comm, &newcomm));

It doesn't crash or anything, just exits the code "normally" with exit 
code 1.
Do you have any idea what is wrong?
