PetscSynchronizedPrintf#

Prints synchronized output from multiple MPI processes. Output of the first processor is followed by that of the second, etc.

Synopsis#

PetscErrorCode PetscSynchronizedPrintf(MPI_Comm comm, const char format[], ...)

Not Collective

Input Parameters#

  • comm - the MPI communicator

  • format - the usual printf() format string

Note#

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). That is, you can only pass a single character string from Fortran.
