Marco, Thanks for the report, and sorry for the delayed response. I can replicate a problem using your test code, but it does not segfault for me (although I am using a different version of Open MPI). I filed a bug on this so (hopefully) out collective gurus will look at it soon. You will re

Unfortunately, I am out of ideas on this one. It is very strange. Maybe someone else has an idea. I would recommend trying to install Open MPI again. First be sure to get rid of all of the old installs of Open MPI from all your nodes, then reinstall and try again. Tim Dino Rossegger wrote:
