Can anyone set my expectations with their real world experiences
regarding building Open MPI on one release of Linux and running on another.

If I were to...
Build OMPI on Redhat 4, will it run on later releases of Redhat, e.g.
Redhat 5?
Build OMPI on Suse 9, will it run on later releases of Suse, e.g. Suse 10?
Build OMPI on Redhat, will it run on Suse?
Build OMPI on Suse, will it run on Redhat?

Thanks in advance for your insights.

The best way I have found to ensure maximum compatibility is to compile a version of GCC that is not tied to any OS, but that is tied to an architecture. I then compile all my applications using that compiler and it has always worked for me.
