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.
