computes a global numbering of PetscObjects living on subcommunicators of a given communicator. This results in a deadlock-free ordering of the subcommunicators and, hence, the objects.

PetscErrorCode PetscObjectsGetGlobalNumbering(MPI_Comm comm, PetscInt len, PetscObject *objlist, PetscInt *count, PetscInt *numbering)
