CppCon 2017: Chandler Carruth “Going Nowhere Faster”

推荐理由

The best presentation I've seen about CPU performance related to pipelining, branch prediction, and speculative execution

说明

这是2017年由CppCon发布的一部演讲，主题归在Software performance & optimization。它讲的是cpu performance tuning这一支里的具体问题，而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成：Chandler Carruth shows how to squeeze more performance out of already-optimized C++ code, covering how the CPU executes it. The talk goes into pipelining, branch prediction and speculative execution using benchmarks.这些读者给出的理由，核心是：Recommended as the best presentation on how modern CPUs run code, and why speculative execution matters for performance.讲法不绑某一条新闻，过几年仍然可以当材料看。从2017年到2026年，有2位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有1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cpu performance tuning变成能跟着复述的例子。
