how to use PetscMap?

[Yixun Liu]

Hi,

I reveive the error as,

[0]PETSC ERROR: ------------------------------------------------------------------------

job aborted:

0: dmrc-6700512: 59: application called MPI_Abort(MPI_COMM_WORLD, 59) - process 0
    
I think this error maybe caused by these codes,

 PetscMap *map;
 ierr = PetscMapInitialize(PETSC_COMM_WORLD, map);
 CHKERRQ(ierr);
 ierr = PetscMapSetSize (map, n);
 ierr = PetscMapGetLocalRange(map,&Istart,&Iend); CHKERRQ(ierr);

Is it correct to use the PetscMap like this?

Best,

Yixun
