 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.
