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.
