Should fillComplete() only be called from the root process?

Quick question... (@tpetra, @csiefer2),
When doing fillComplete() is it required to only call fillComplete() from the root process (when using MPI)?
for example:

RCP< const Teuchos::Comm<int> > comm = Teuchos::DefaultComm<int>::getComm();
int rank   = comm->getRank();

// do matrix fill

if (rank==0) {
  matrixA->fillComplete();
}

No, it should be called on every rank in the communicator.

ok, thank you!
