[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 -- Riccardo Murri, Hadlaubstr. 150, 8006 Zürich (CH)
