PetscViewerASCIISynchronizedPrintf
Prints synchronized output to the specified file from several processors. Output of the first processor is followed by that of the second, etc.
Synopsis
#include "petscviewer.h"
PetscErrorCode PetscViewerASCIISynchronizedPrintf(PetscViewer viewer,const char format[],...)
Not Collective, must call collective PetscViewerFlush() to get the results out
Input Parameters
| viewer | - the ASCII PetscViewer
|
| format | - the usual printf() format string
|
Notes
You must have previously called PetscViewerASCIIPushSynchronized() to allow this routine to be called.
Then you can do multiple independent calls to this routine.
The actual synchronized print is then done using PetscViewerFlush().
PetscViewerASCIIPopSynchronized() should be then called if we are already done with the synchronized output
to conclude the "synchronized session".
So the typical calling sequence looks like
PetscViewerASCIIPushSynchronized(viewer);
PetscViewerASCIISynchronizedPrintf(viewer, ...);
PetscViewerASCIISynchronizedPrintf(viewer, ...);
...
PetscViewerFlush(viewer);
PetscViewerASCIISynchronizedPrintf(viewer, ...);
PetscViewerASCIISynchronizedPrintf(viewer, ...);
...
PetscViewerFlush(viewer);
PetscViewerASCIIPopSynchronized(viewer);
Fortran Note
Can only print a single character* string
