So to Robert's question, I don't think this is something that could be baked into the boost_mpi.so library, since they rely on my own classes. ...

look at .../libs/serialization/src/binary_oarchive.cpp

This file contains the explict instantiations that are added to the library. I would expect that something like this could be made for mpi archives.

I think you're right Robert. I can get my types to serialize fine with the boost::binary_*archive archives, but not with the mpi ones. It's strange because I can get it to work for send, but not recv. I get an exception related to unregistered type.

Indeed if I go and manually serialize every message pointer to a char buffer vis binary_oarchive, and send that via boost mpi, and manually deserialize on the other side from char buffer via binary_iarchive, my program works.

I'm unsure what exactly might need to be instantiated in boost::mpi though.

just use binary_iarchive as a guide for mpi_archive.

Thanks, Brian
