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_view), which is
intended for production runs since it logs only flop rates and object
creation (and should not significantly slow the programs).
