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

Hi Riccardo, Sorry for the late reply - I have been away from the internet for a few weeks and only slowly catch up with my e-mail. AFAIK Doug Gregor did not finish the bjam support for BOOST_MPI_HOMOGENEOUS, thus just comment out that line you refer to. Matthias
