Hi people,

should we define a provides=("mpi") or something like that in openmpi and mpich2, and eventually also other possible mpi implementations? That way a number of mpi-dependent packages will be made undependent of the chosen mpi implementation one wants to install.

Not that my voice matters much but I agree on that. It's the same kind of thing than depending on java-runtime vs. JRE, especially since MPI was specifically designed as a specification that could have multiple implementations. Packagers will have to be careful though since some functions do not work exactly the same way in every implementation... -- Pierre 'catwell' Chapuis
