I assumed that. OpenMPI recently moved to using gcc atomics where available, which means we no longer need to ship patches for each architecture. So I expect OpenMPI to work on all archs before stretch. >> Besides, do we know whether openmpi works correctly on those >> architectures?

This will involve a transition: https://release.debian.org/transitions/html/auto-openmpi.html Thanks for pointing to the mpi-testsuite results. I wasn't aware they are do bad. I'll investigate. OpenMPI 1.10.3 is "mostly ok" according to: https://buildd.debian.org/status/package.php?p=openmpi&suite=unstable I've openmpi2 in experimental: https://buildd.debian.org/status/package.php?p=openmpi&suite=experimental I'm working with upstream and hoping to add symbol versioning, as the regular soname changes are quite problematic. > Currently I've stopped all hppa buildds and plan to upgrade them to gcc6 > before starting them again.
