# 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

### Notes

A related routine is PetscLogDefaultBegin() (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).
