typedef enum {PETSCSF_SYNCHRONIZATION_FENCE,PETSCSF_SYNCHRONIZATION_LOCK,PETSCSF_SYNCHRONIZATION_ACTIVE} PetscSFSynchronizationType;
PETSCSF_SYNCHRONIZATION_FENCE - simplest model, synchronizing across communicator
PETSCSF_SYNCHRONIZATION_LOCK - passive model, less synchronous, requires less setup than PETSCSF_SYNCHRONIZATION_ACTIVE, but may require more handshakes
PETSCSF_SYNCHRONIZATION_ACTIVE - active model, provides most information to MPI implementation, needs to construct 2-way process groups (more setup than PETSCSF_SYNCHRONIZATION_LOCK)
