A global counter logs all PETSc flop counts. The user can use
<A HREF="../Profiling/PetscLogFlops.html#PetscLogFlops">PetscLogFlops</A>() to increment this counter to include flops for the
application code.
<P>
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. <A HREF="../Profiling/PetscLogFlops.html#PetscLogFlops">PetscLogFlops</A>() is
intended for logging user flops to supplement this PETSc
information.
