Several solutions were [2]discussed. The easiest and most robust is
to conflict with all the non-default implementations of mpi-dev. A
smoother solution is to provide links like mpicc.default pointing
to the right implementation, and install

Actually, the information I was missing is that some packages depend
on
mpi-default-dev. I thought that mpi-default-dev was only used as a
build-dependency. In that case, conflicting is indeed harmful, so the
only solution is the

But there is still one thing I do not get: What problem is solved by
installing mpicc.default as alternative? If the sysadmin did change
the
MPI implementation via update-alternatives, it will stay that way. It
has no benefit over simply
Hi Thibaut,
thanks for clarifying! It seems to me that we share the same opinion in
(almost) all points but have a different view on the topic.

So, given that the priority in Open MPI changed and we will
transition,
do you think the patch is useful? I do not refrain from applying it to
mpi-default but my understanding is that we do not need to have it
as of
now.
No, with

No, with the prioriy of OpenMPI raised above that of MPICH2, and with
the idea of switching from LAM to MPICH2 on the other arches, my patch
does not bring any _immediate_ benefit. It's a proposal for a longer

As discussed on [1]debian-science, the way mpi-default-dev works does

that the right MPI implementation is used. For instance, if libmpich2-
