f -flop counter
Synopsis
void PetscLogFlops(int f)
Usage
int USER_EVENT;
PetscLogEventRegister(&USER_EVENT,"User event");
PetscLogEventBegin(USER_EVENT,0,0,0,0);
[code segment to monitor]
PetscLogFlops(user_flops)
PetscLogEventEnd(USER_EVENT,0,0,0,0);
Notes
A global counter logs all PETSc flop counts. The user can use
PetscLogFlops() to increment this counter to include flops for the
application code.
PETSc automatically logs library events if the code has been
compiled with -DPETSC_USE_LOG (which is the default), and -log,
-log_summary, or -log_all are specified. PetscLogFlops() is
intended for logging user flops to supplement this PETSc
information.
