Notes

REQUIRES a call to PetscSynchronizedFlush() by all the processes after the completion of the calls to PetscSynchronizedPrintf() for the information from all the processors to be printed.

Fortran Note

The call sequence is PetscSynchronizedPrintf(MPI_Comm, character(*), PetscErrorCode ierr) from Fortran. That is, you can only pass a single character string from Fortran.
