PetscLogAllBegin

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

Synopsis

#include "petsc.h"   
int PetscLogAllBegin(void)

Collective on PETSC_COMM_WORLD

Options Database Keys

-log_all -Prints extensive log information (for code compiled with PETSC_USE_LOG)

Usage

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

Notes

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