Whetstone
     
         The first major {synthetic benchmark} program,
        intended to be representative for numerical ({floating-point}
        intensive) programming.  It is based on statistics gathered by
        Brian Wichmann at the {National Physical Laboratory} in
        England, using an {Algol 60} {compiler} which translated Algol
        into instructions for the imaginary Whetstone machine.  The
        compilation system was named after the small town of Whetstone
        outside the City of Leicester, England, where it was designed.
     
        The later {dhrystone} benchmark was a pun on Whetstone.
