void PetscLogEventBegin(int e,PetscObject o1,PetscObject o2,PetscObject o3, PetscObject o4)
int USER_EVENT; int user_event_flops; PetscLogEventRegister(&USER_EVENT,"User event"); PetscLogEventBegin(USER_EVENT,0,0,0,0); [code segment to monitor] PetscLogFlops(user_event_flops); PetscLogEventEnd(USER_EVENT,0,0,0,0);
PETSc automatically logs library events if the code has been compiled with -DPETSC_USE_LOG, and -log, -log_summary, or -log_all are specified. PetscLogEventBegin() is intended for logging user events to supplement this PETSc information.
