1418    Notes:
1419      There is also a PetscPartitioner object that provides the same functionality. It can utilize the MatPartitioning operations
1420      via PetscPartitionerSetType(p,PETSCPARTITIONERMATPARTITIONING)
1421 
1422    Developers Note:
1423      It is an extra maintainance and documentation cost to have two objects with the same functionality.
