Comment (by dledford):
Environment modules comes into play *any* time openmpi is used. Whether
building or running an application. You can't just run an mpi app, it
must be started by the mpi runtime (which isn't available without the
environment module being loaded). And you can't just link against mpi
libraries, they are added to your app by mpicc (or one of the other
compiler wrappers). Anyone attempting to make a generic shared library
that links against mpi libraries and then is used by a subsequent
application without knowing about the mpi stack is a non-starter.
As for more than one version, you can never have more than one version in
a repo at a time, but you have all released versions archived via koji and
have access to them, and you have the option to tell yum to just install
new openmpi versions instead of upgrading. The support for multiple
versions exists in the package, not in the infrastructure, so it does take
some work to get multiple versions installed, but once done, it works just
fine.
