摘要

作者在并行处理的背景下考察了Amdahl定律，并就该定律的真正适用性提供了一些论证。Amdahl定律确定了给定应用程序中存在的顺序代码的比例的可用并行性的上限。本文重新考察了阿姆达尔定律，以推导出一个公式，使人们能够进行一些定量分析。MPPs(大规模并行处理器)是特殊用途系统的说法也得到了解决。

MPPs, Amdahl's law, and comparing computers

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.<>
