PetscSFConcatenateRootMode

Modes of root concatenation when concatenating PetscSFs

Synopsis

typedef enum {
  PETSCSF_CONCATENATE_ROOTMODE_LOCAL,
  PETSCSF_CONCATENATE_ROOTMODE_SHARED,
  PETSCSF_CONCATENATE_ROOTMODE_GLOBAL,
} PetscSFConcatenateRootMode;

Values

• PETSCSF_CONCATENATE_ROOTMODE_LOCAL - concatenate root spaces locally (separately on each rank)

• PETSCSF_CONCATENATE_ROOTMODE_SHARED - do not concatenate roots; root space is considered the same for each input PetscSF (checked in debug mode)
