# PetscSFWindowSyncType

Type of synchronization for PETSCSFWINDOW

### Synopsis

    typedef enum {PETSCSF_WINDOW_SYNC_FENCE,PETSCSF_WINDOW_SYNC_LOCK,PETSCSF_WINDOW_SYNC_ACTIVE} PetscSFWindowSyncType;

     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)
