Writing Cache-Friendly C++

Speaker: Jonathan Müller

Audience level: Beginner | Intermediate | Advanced


When you need a container, pick std::vector<T> by default. This is common advice.

Why? Because std::vector<T> is cache-friendly.

This talk will quickly explain what it means, why it is so important, and how to write cache-friendly code yourself. We will look at the design and implementation of awesome cache-friendly containers the standard library lacks, a range of tricks (and hacks) to fit as many objects into the cache as possible, as well as big picture structural program changes for data oriented design.

This will be a practical hands-on talk featuring a lot of code and benchmarks. Everything implementation presented is available in a library for you to use.
