hello Robert,
now that serialization is working, i would like to try what you suggested on the first messages, mixing plain MPI with serialization is not that bad,
if its possible could you guide me a little more hints on the streambuf structure. at the moment what i can do is save objects into binary_oarchive and read them with a binary_iarchive.
what i dont know is where to put the binary_oarchive so it gets transfered through MPI send as bytes. that would be the only step remaining right? best regards Cristobal You should first investigate Matthias suggestion. This will be equivalent or better than my suggestion and it's already done and ready go to.
Use a packed_iarchive and a packed_oarchive and then look at the functions in point_to_point.cpp for instructions on how to send the buffer. Or, even ssimpler, just use send and recv of Boost.MPI since that does exactly what you want to do. Matthias
