Foil 29 Amdahl's law for Real World Parallel Processing

From New CPS615 Foils 25 March95 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox

AMDAHL"s LAW or

Too many cooks spoil the broth

Says that

Speedup S is small if efficiency e small

or for Hadrian's wall

equivalently S is small if length l small

But this is irrelevant as we do not need parallel processing unless problem big!
