在追求更高性能數字的「淘金熱」中，超級電腦引入了許多混亂。本文試圖通過對術語的基本概念、貢獻、計量方法等方面來進行梳理。梳理結果表明，在計算系統中使用大量的處理元素會導致出現一些無法用經典計算範式解釋的意外現象。這些現象與一個多世紀以前的科學現象有有趣的相似之處，並通過他們對現代科學的研究而被引入。引入的簡單但非技術的模型能夠建立一個框架和形式來解釋超級電腦中無法解釋的體驗。該模型還可以預測超級電腦在不久的將來的性能，並為增強超級電腦的組件提供提示。
原文標題：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.
