# PetscSFNode
specifier of owner and index 
## Synopsis
```
typedef struct {
  PetscInt rank;  /* Rank of owner */
  PetscInt index; /* Index of node on rank */
} PetscSFNode;
```



## Sample Usage
```none
    PetscSFNode    *remote;
    PetscCall(PetscMalloc1(nleaves,&remote));
    for (i=0; i<size; i++) {
      remote[i].rank = i;
      remote[i].index = rank;
    }
```



## Sample Fortran Usage
```none
    type(PetscSFNode) remote(6)
    remote(1)%rank  = modulo(rank+size-1,size)
    remote(1)%index = 1 * stride
```
