[Boost-users] [MPI] optimization for homogeneous clusters

Hello,

The manual for Boost.MPI 1.43.0 states: "More optimizations are
possible on homogeneous machines, by avoiding MPI_Pack/MPI_Unpack
calls but using direct bitwise copy. This feature can be enabled by
defining the macro BOOST_MPI_HOMOGENEOUS when building Boost.MPI and
when building the application."

What is the correct way of building Boost.MPI for homogeneous systems?
Should I just uncomment the relevant line in boost/mpi/config.hpp, or
is there another (and recommended) way through Jam files?

Thank you very much in advance for any suggestion.

Best regards,
Riccardo
