PetscSFDuplicateOption#

Aspects to preserve when duplicating a PetscSF

Synopsis#

typedef enum {
  PETSCSF_DUPLICATE_CONFONLY,
  PETSCSF_DUPLICATE_RANKS,
  PETSCSF_DUPLICATE_GRAPH
} PetscSFDuplicateOption;

`PETSCSF_DUPLICATE_CONFONLY` - configuration only, user must call `PetscSFSetGraph()`

`PETSCSF_DUPLICATE_RANKS` - communication ranks preserved, but different graph (allows simpler setup after calling `PetscSFSetGraph()`)

`PETSCSF_DUPLICATE_GRAPH` - entire graph duplicated
