how to use PetscMap?

[Yixun Liu]

Hi,

I want to change the code, which is based on old version PETSC to version 2.3.2. The old petsc code are,

PetscMap map;
ierr = PetscMapCreateMPI(PETSC_COMM_WORLD,PETSC_DECIDE,n,&map);CHKERRQ(ierr);
ierr = PetscMapGetLocalRange(map,&Istart,&Iend); CHKERRQ(ierr);
ierr = PetscMapDestroy(map); CHKERRQ(ierr);

If 2.3.2 does not support PetscMap, which class should I use?

Best,

Yixun
