AOCreateMapping#

Creates an 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 the 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()

Note#

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.
