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 on PETSC_COMM_WORLD

Options Database Key#

  • -log_mpe - Prints extensive log information

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 should not significantly slow the programs).
