C o Get rid of vertical resolution dependence of dVsq term by
C   estimating a surface velocity that is independent of first
C   level thickness in the model.
#undef KPP_ESTIMATE_UREF

C o When set, test denominators for small values
C   makes code adjoint-friendly by avoiding singularities in
C   the forward code and its derivative
#define KPP_TEST_DENOM

C o When set, use exchange calls rather than recomputation
C   to obtain KPP parameters in overlap region.  This option
C   was added to reduce stack size requirements on the
C   Origin 2000.  It decreases memory and computation
C   requirements at the expense of increased communications.
C   For a 64-processor 360x224x46 MPI configuration on the
C   Exemplar or Origin 2000, wall clock time is about the
C   same whether FRUGAL_KPP is turned on or off.

C o When set, smooth zonal shear meridionally and
C   meridional shear zonally with 121 filters

C o When set, smooth all KPP density variables horizontally
