@haraldkl Thanks for the quick fix! I have verified it under my tests, and it behaves as expected. The decomposition still results in disjoint blocks within one partition, which is consistent with your expectation.

Thanks @MikeW097 the fix has now been merged back into the main branch and 2dce710 should now be usable. An advantage of using OpenMP is then also that you increase the MPI partition sizes (by reducing the number of partitions).
