PetscSFWindowSyncType

Type of synchronization for PETSCSFWINDOW

Synopsis

typedef enum {
  PETSCSF_WINDOW_SYNC_FENCE,
  PETSCSF_WINDOW_SYNC_LOCK,
  PETSCSF_WINDOW_SYNC_ACTIVE
} PetscSFWindowSyncType;

Values

• PETSCSF_WINDOW_SYNC_FENCE - simplest model, synchronizing across communicator

• PETSCSF_WINDOW_SYNC_LOCK - passive model, less synchronous, requires less setup than PETSCSF_WINDOW_SYNC_ACTIVE, but may require more handshakes

• PETSCSF_WINDOW_SYNC_ACTIVE - active model, provides most information to MPI implementation, needs to construct 2-way process groups (more setup than PETSCSF_WINDOW_SYNC_LOCK)
