These 16 * facilities are useful when the data in a stable data structure 17 * (e.g., a mesh or a graph) will need to be transmitted 18 * repeatedly. In this case, transmitting the skeleton only once 19 * saves both communication effort (it need not be sent again) and 20 * local computation (serialization need only be performed once for 21 * the content). 22 */ 23 #ifndef BOOST_MPI_SKELETON_AND_CONTENT_HPP 24 #define BOOST_MPI_SKELETON_AND_CONTENT_HPP 25 26 #include <boost/mpi/config.hpp> 27 #include <boost/archive/detail/auto_link_archive.hpp> 28 #include <boost/mpi/skeleton_and_content_types.hpp> 29 30 namespace boost { namespace mpi { 31 32 namespace detail { 33 typedef boost::mpi::detail::forward_skeleton_oarchive<boost::mpi::packed_skeleton_oarchive,boost::mpi::packed_oarchive> type1; 34 typedef boost::mpi::detail::forward_skeleton_iarchive<boost::mpi::packed_skeleton_iarchive,boost::mpi::packed_iarchive> type2; 35 } 36 37 38 } } // end namespace boost::mpi 39 40 #include <boost/mpi/detail/content_oarchive.hpp> 41 42 // For any headers that have provided declarations based on forward 43 // declarations of the contents of this header, include definitions 44 // for those declarations.
