AOCreateMapping

Creates a basic application mapping using two integer arrays.

Synopsis

#include "petscao.h" 
PetscErrorCode  AOCreateMapping(MPI_Comm comm,PetscInt napp,const PetscInt myapp[],const PetscInt mypetsc[],AO *aoout)

Input Parameters

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 identity ordering)

Output Parameter

aoout -the new application mapping

Options Database Key

-ao_view : call AOView() at the conclusion of AOCreateMapping()

Notes: the arrays myapp and mypetsc need NOT contain the all the integers 0 to napp-1, that is there CAN be "holes" in the indices. Use AOCreateBasic() or AOCreateBasicIS() if they do not have holes for better performance.
