BOOST_MPI_HOMOGENEOUS — Comment this macro is you are running in an heterogeneous environment.
// In header: <boost/mpi/config.hpp> BOOST_MPI_HOMOGENEOUS
When this flag is enabled, we assume some simple, POD-like, type can be transmitted without paying the cost of portable serialization.
Comment this if your platform is not homogeneous and that portable serialization/deserialization must be performed.
It you do so, check that your MPI implementation supports thats kind of environment.
