PetscLogMPEBegin

Turns on MPE logging of events. This creates large log files and slows the program down.

Synopsis

#include "petscsys.h"   
PetscErrorCode  PetscLogMPEBegin(void)
Collective over PETSC_COMM_WORLD

Options Database Keys

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

Notes

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