Subject: [OMPI users] Upgrade from Open MPI 1.2 to 1.3
From: Serge (skhan_at_[hidden])

Hello,

We have a number of applications built with Open MPI 1.2 in a shared
multi-user environment. The Open MPI library upgrade has been always
transparent and painless within the v1.2 branch. Now we would like to
switch to Open MPI 1.3 as seamlessly. However, an application built with
ompi v1.2 will not run with the 1.3 library; the typical error messages
are given below. Apparently, the type ompi_communicator_t has changed.

Symbol `ompi_mpi_comm_null' has different size in shared object,
consider re-linking
Symbol `ompi_mpi_comm_world' has different size in shared object,
consider re-linking

Do I have to rebuild all the applications with Open MPI 1.3?

Is there a better way to do a smooth upgrade?

Thank you.
