CppCon 2014: Chandler Carruth "Efficiency with Algorithms, Performance with Data Structures"

推荐理由

I'm also a big fan of "Efficiency with Algorithms, Performance with Data Structures" by Chandler Carruth at CppCon 2014.

说明

这是2014年由CppCon发布的一部演讲，主题归在Software performance & optimization。它讲的是c++ performance这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Chandler Carruth's CppCon 2014 talk on writing fast C++, explaining why data structure choice and memory layout matter more than clever algorithms. It covers why standard containers like unordered_map perform poorly on modern CPUs.这些读者给出的理由，核心是：A perennial recommendation for anyone learning performance optimization, cited whenever hash tables, cache behavior or STL containers come up.讲法不绑某一条新闻，过几年仍然可以当材料看。从2014年到2024年，有7位不同的读者在7个不同月份把它推荐出来，其中明确叫别人去看的有2次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把c++ performance变成能跟着复述的例子。
