#include "petscsys.h" PetscErrorCode PetscObjectsListGetGlobalNumbering(MPI_Comm comm, PetscInt len, PetscObject *objlist, PetscInt *count, PetscInt *numbering)
Collective on comm.
| comm | - MPI_Comm | |
| len | - local length of objlist | |
| objlist | - a list of PETSc objects living on subcomms of comm and containing this comm rank (subcomm ordering is assumed to be deadlock-free) |
| count | - global number of distinct subcommunicators on objlist (may be > len) | |
| numbering | - global numbers of objlist entries (allocated by user) |
