The geometric mean of P1,..,Pn is
_____________
/ n
Geometric Mean = n / __
/ || Normalized(Pi)
\/ i=1
where Normalized(Pi) = Pi / Pn where n is the referenced execution time. Obviously the
geometic mean of the referenced machine is 1.One of the nice features of Geometric means is that the following property holds:
GeometricMean(Xi)
GeometricMean(Xi/Yi) = ------------------
