#include <petsclog.h>
PetscErrorCode PetscLogFlops(PetscLogDouble f)
Not Collective
Input Parameter#
f - flop counter
Usage#
PetscLogEvent USER_EVENT;
PetscLogEventRegister("User event",0,&USER_EVENT);
PetscLogEventBegin(USER_EVENT,0,0,0,0);
[code segment to monitor]
PetscLogFlops(user_flops)
PetscLogEventEnd(USER_EVENT,0,0,0,0);
Note#
A global counter logs all PETSc flop counts. The user can use PetscLogFlops() to increment this counter to include flops for the application code.
