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.
