PetscSynchronizedFPrintf

Prints synchronized output to the specified file from several MPI processes. Output of the first process is followed by that of the second, etc.

Synopsis

PetscErrorCode PetscSynchronizedFPrintf(MPI_Comm comm, FILE *fp, const char format[], ...)

Not Collective

Input Parameters

• comm - the MPI communicator

• fp - the file pointer, PETSC_STDOUT or value obtained from PetscFOpen()

• format - the usual printf() format string

Note

REQUIRES a intervening call to PetscSynchronizedFlush() for the information from all the processors to be printed.

Fortran Note

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