# PetscSFNode

specifier of owner and index

### Synopsis

    typedef struct {
      PetscInt rank;                /* Rank of owner */
      PetscInt index;               /* Index of node on rank */
    } PetscSFNode;

### Sample Usage

         PetscSFNode    *remote;

       ierr = PetscMalloc1(nleaves,&remote);CHKERRQ(ierr);

       for (i=0; i<size; i++) {

         remote[i].rank = i;

         remote[i].index = rank;

       }

### Sample Fortran Usage

        type(PetscSFNode) remote(6)

         remote(1)%rank  = modulo(rank+size-1,size)

         remote(1)%index = 1 * stride
