关于内存，每个程序员都应该知道什么? [英] What Every Programmer Should Know About Memory?

问题描述

我想知道 Ulrich Drepper 2007 年的每个程序员应该了解的内存中有多少仍然有效的.我也找不到比 1.0 更新的版本或勘误表.

I am wondering how much of Ulrich Drepper's What Every Programmer Should Know About Memory from 2007 is still valid. Also I could not find a newer version than 1.0 or an errata.

(在 Ulrich Drepper 自己的网站上也有 PDF 格式:https://www.akkadia.org/drepper/cpumemory.pdf)

推荐答案

据我所知，Drepper 的内容描述了有关内存的基本概念:CPU 缓存如何工作、物理和虚拟内存是什么以及 Linux 内核如何处理该动物园.在某些示例中可能存在过时的 API 引用，但这并不重要；这不会影响基本概念的相关性.

As far as I remember Drepper's content describes fundamental concepts about memory: how CPU cache works, what are physical and virtual memory and how Linux kernel deals that zoo. Probably there are outdated API references in some examples, but it doesn't matter; that won't affect the relevance of the fundamental concepts.

因此，任何描述基本知识的书籍或文章都不能称为过时.每个程序员都应该了解的内存知识"绝对值得一读，但是，我不认为它适合每个程序员".更适合系统/嵌入式/内核人员.

So, any book or article that describes something fundamental cannot be called outdated. "What every programmer should know about memory" is definitely worth to read, but, well, I don't think it's for "every programmer". It's more suitable for system/embedded/kernel guys.
