论文摘要
本文解释了为什么应专门解释Amdahl的定律,以解释为分布式平行系统,以及为什么它引起了如此多的辩论,讨论和虐待。我们设置了一个通用模型,并列出了影响并行处理的许多术语。我们仔细研究了在不同近似值中忽略某些术语的有效性,并特别强调了并行处理的著名缩放定律。我们澄清说,当使用正确的术语解释时,Amdahl的定律是各种并行处理的法律。 Amdahl的定律将超级计算的历史描述为各种并行处理的固有性能限制,而“现代计算”范式的基本定律迫切需要在极端计算条件下工作的计算系统的基本定律。
The paper explains why Amdahl's Law shall be interpreted specifically for distributed parallel systems and why it generated so many debates, discussions, and abuses. We set up a general model and list many of the terms affecting parallel processing. We scrutinize the validity of neglecting certain terms in different approximations, with special emphasis on the famous scaling laws of parallel processing. We clarify that when using the right interpretation of terms, Amdahl's Law is the governing law of all kinds of parallel processing. Amdahl's Law describes among others the history of supercomputing, the inherent performance limitation of the different kinds of parallel processing and it is the basic Law of the 'modern computing' paradigm, that the computing systems working under extreme computing conditions are desperately needed.
