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

If one were using heterogenious machines, I could understand the usage of MPI types. But as I understand it, the MPI serialization presumes that the machines are binary compatible.
You're mistaken.
So I'm just not seeing this.
Start reading here:
http://www.boost.org/doc/libs/1_39_0/doc/html/mpi/tutorial.html#mpi.skeleton...
and all will be revealed
lol - I've read that several times. I just never found it to be very revealing. The word skeleton seemed pretty suggestive. It's still not clear to me how such a think can work between heterogeneous machines. For example, if I have an array of 2 byte integers and they each need to get transformed one by one into a 4 byte integer because that's closest MPI data type, I don't see how the fact that the "shape" doesn't change helps you. So when I read the documentation I didn't find an obvious answer to this question. Admitadly my attention span is pretty short when I'm looking at something just because I'm curious rather than really needing a solution to my problem. So maybe its OK if one has more time to spend on it.
