最后,超级电脑效率多少?它们衡量的是什么?(Performance)

在追求更高性能数字的“淘金热”中,超级电脑引入了许多混乱。本文试图通过对术语的基本概念、贡献、计量方法等方面来进行梳理。梳理结果表明,在计算系统中使用大量的处理元素会导致出现一些无法用经典计算范式解释的意外现象。这些现象与一个多世纪以前的科学现象有有趣的相似之处,并通过他们对现代科学的研究而被引入。引入的简单但非技术的模型能够建立一个框架和形式来解释超级电脑中无法解释的体验。该模型还可以预测超级电脑在不久的将来的性能,并为增强超级电脑的组件提供提示。

原文标题:Performance:Finally, how many efficiencies the supercomputers have? And, what do they measure?

In the "gold rush" for higher performance numbers, a lot of confusion was introduced in supercomputing. The present paper attempts to clear up the terms through scrutinizing the basic terms, contributions, measurement methods. It is shown that using extremely large number of processing elements in computing systems leads to unexpected phenomena, that cannot be explained in the frame of the classical computing paradigm. The phenomena show interesting parallels with the phenomena experienced in science more than a century ago and through their studying a modern science was introduced. The introduced simple non-technical model enables to set up a frame and formalism enabling to explain the unexplained experiences around supercomputing. The model also enables to derive predictions of supercomputer performance for the near future as well as provides hints for enhancing supercomputer components.
