PetscLogAllBegin#

Turns on extensive logging of objects and events. Logs all events. This creates large log files and slows the program down.

Synopsis#

#include "petscsys.h"   
PetscErrorCode PetscLogAllBegin(void)

Logically Collective on PETSC_COMM_WORLD

Options Database Key#

  • -log_all - Prints extensive log information

Usage#

     PetscInitialize(...);
     PetscLogAllBegin();
     ... code ...
     PetscLogDump(filename);
     PetscFinalize();

Note#

A related routine is PetscLogDefaultBegin() (with the options key -log_view), which is intended for production runs since it logs only flop rates and object creation (and shouldn’t significantly slow the programs).
