Hi, I'd like to draw your attention to an on-going discussion wrt. OpenMPI and upgrades:
https://github.com/open-mpi/ompi/issues/1906 Basically, I'd like to know: did we ever successfully support upgrades of openmpi in Debian? Currently, because of unversioned plugins, libopenmpi2 will conflict with libopenmpi1.10.3 (and libopenmpi1.10, and libopenmpi1.6, libopenmpi1, ... ). This is suboptimal, especially if we grow the number of packages built against mpi. At the moment, the best solution seems to be: * put the unversioned plugins in a versioned directory $blah/2.0.0/*.so accessed via RPATH from the libopenmpi* libraries * Add versioned symbols to OpenMPI. This would be significant work, and in practice have to be led by Debian (err, yes, I could do it). I'd like comments on this before proceeding.
