Source: openmpi Version: 3.1.0-7 Severity: important OpenMPI 3 on ppc64el seems unstable: the test suite for dune-grid only passes ~30% of the time on ppc64el. In the other cases it hangs in MPI communication or gets unexpected results.
I haven't been able to find a simpler test case yet (unlike armel, #902041). (Maybe related: on powerpc all MPI tests in dune-grid just run into a timeout, but that one is not a release arch so I care less.) Ansgar
