AOCreateMappingIS#
Creates a basic application ordering using two index sets.
Synopsis#
#include "petscao.h"
PetscErrorCode AOCreateMappingIS(IS isapp, IS ispetsc, AO *aoout)
Input Parameters#
comm - MPI communicator that is to share AO
isapp - index set that defines an ordering
ispetsc - index set that defines another ordering, maybe NULL for identity IS
Output Parameter#
aoout - the new application ordering
Options Database Key#
-ao_view - call AOView() at the conclusion of AOCreateMappingIS()
Notes#
the index sets isapp and ispetsc need NOT contain the all the integers 0 to N-1, that is there CAN be “holes” in the indices. Use AOCreateBasic() or AOCreateBasicIS() if they do not have holes for better performance.
