Well from what I know Boost.MPI contains only MPI-1 functions <br>(but refer to the boost mailing list for support <a href="http://lists.boost.org/mailman/listinfo.cgi/boost-users">http://lists.boost.org/mailman/listinfo.cgi/boost-users</a>);<br>
so Intercommunicators  are not managed by the Boost.MPI library, and you have to use the stardard MPI functions.<br><br>So, by now, I think it&#39;s not possible to send a user defined serializable object through an intercommunicator.<br>

Greetings all,<br>
<br>
I wanted to send come complex user defined types between MPI processes and found out that Boost.MPI is  quite easy to use for my requirement.So far it worked well and I received my object model in every process without problems.<br>

Now I am going to spawn processes (using MPI_Comm_spawn, because Boot.MPI doesn&#39;t have such a function) and then use Boost.MPI to send the objects across newly created child processes.<br>
Is there any issues with this procedure?<br>
And Boost.MPI says it only support OpenMPI 1.0.x (<a href="http://www.boost.org/doc/libs/1_40_0/doc/html/mpi/getting_started.html#mpi.mpi_impl" target="_blank">http://www.boost.org/doc/libs/1_40_0/doc/html/mpi/getting_started.html#mpi.mpi_impl</a>)<br>

Will there be any version incompatibilities ?<br>
<br>
thanks in advance,<br>
umanga<br>
