#include "petscao.h" PetscErrorCode AOCreateBasic(MPI_Comm comm,PetscInt napp,const PetscInt myapp,const PetscInt mypetsc,AO *aoout)Collective on MPI_Comm
|comm||- MPI communicator that is to share AO|
|napp||- size of integer arrays|
|myapp||- integer array that defines an ordering|
|mypetsc||- integer array that defines another ordering (may be NULL to indicate the natural ordering, that is 0,1,2,3,...)|
Notes: the arrays myapp and mypetsc must contain the all the integers 0 to napp-1 with no duplicates; that is there cannot be any "holes" in the indices. Use AOCreateMapping() or AOCreateMappingIS() if you wish to have "holes" in the indices.
