Abstract :
The author examines Amdahl´s law in the context of parallel processing and provides some arguments as to what the applicability of this law really is. Amdahl´s law establishes an upper bound on the available parallelism given the fraction of sequential code present in an application. In this paper, Amdahl´s law is revisited to derive a formulation which allows one to carry out some quantitative analysis. The claim that MPPs (massively parallel processors) are special-purpose systems is also addressed
