But its nice to choose a bunch of nodes and then a second one in the same
application and see the differences.
Its ordinary C mpi surrounded by a C++ Qt gui.

Yes it is.
Its probably possible to make software packages available for common linux
distributions. But if you have to consider several mpi implementations extra,
that could be lot of packages.
I've you have written a major application like ls-dyna you can say:
Take these linux, these compiler and this mpi and you get our compiled
version, but nobody will alter their cluster for an add-on program like a
So the only choice is to go opensource.
But in some areas it is important that (small or large) companies make
professional, supported software available. But this isn't easy with mpi.
