PetscLogEventsPause#
Put event logging into “paused” mode: timers and counters for in-progress events are paused, and any events that happen before logging is resumed with PetscLogEventsResume() are logged in the “Main Stage” of execution.
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscLogEventsPause(void)
Not collective
Notes#
When an external library or runtime has is initialized it can involve lots of setup time that skews the statistics of any unrelated running events: this function is intended to isolate such calls in the default log summary (PetscLogDefaultBegin(), PetscLogView()).
Other log handlers (such as the nested handler, PetscLogNestedBegin()) will ignore this function.
