If <A HREF="../Sys/PetscSynchronizedPrintf.html#PetscSynchronizedPrintf">PetscSynchronizedPrintf</A>() and/or <A HREF="../Sys/PetscSynchronizedFPrintf.html#PetscSynchronizedFPrintf">PetscSynchronizedFPrintf</A>() are called with
different MPI communicators there must be an intervening call to <A HREF="../Sys/PetscSynchronizedFlush.html#PetscSynchronizedFlush">PetscSynchronizedFlush</A>() between the calls with different MPI communicators.
<P>
From Fortran pass PETSC_STDOUT if the flush is for standard out; otherwise pass a value obtained from <A HREF="../Sys/PetscFOpen.html#PetscFOpen">PetscFOpen</A>()
