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
