PetscSynchronizedFlush

Flushes to the screen output from all processors involved in previous PetscSynchronizedPrintf()/PetscSynchronizedFPrintf() calls.

PetscErrorCode  PetscSynchronizedFlush(MPI_Comm comm,FILE *fd)

Collective on MPI_Comm

	comm	- the communicator
	fd	- the file pointer (valid on process 0 of the communicator)

If PetscSynchronizedPrintf() and/or PetscSynchronizedFPrintf() are called with different MPI communicators there must be an intervening call to PetscSynchronizedFlush() between the calls with different MPI communicators.

From Fortran pass PETSC_STDOUT if the flush is for standard out; otherwise pass a value obtained from PetscFOpen()
