void pmdb_dref_numb_own_gen( pMeshPB pmeshpb)
This function should be called after refinement and derefinement to global number the newly created entities and to establish the ownership information for the shared partition boundary entities. Note that global numbering is not necessary theoretically for migration algorithm to work. However, it is provided since it helps in debugging. Currently, PMDB provides it automatically. Nevertheless, global numbering uses memory as well as computational cost since the whole mesh has to be traversed locally on each processor. A future version of PMDB will make it optional and require call to only pmdb_dref_own_gen.
