Boost.MPI is layered on top of plain MPI; it basically provides a mapping from complex and user-defined C++ data types to MPI datatypes. The added overhead depends on how complex the C++ data structures are; there are some tweaks and hints that can reduce the overhead, it's all explained in the manual. There are also some performance comparison available in the Boost.MPI manual: http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/performance.html Best regards, Riccardo P.S. I think discussion of Boost.MPI is off-topic on the OMPI mailing list; feel free to email me privately or move discussion to the Boost.MPI mailing-list.
