More than a rehash – Joaquín M. López in Madrid at Using std::cpp

In this talk, Joaquín will invite you to look under boost::unordered_flat_map's hood with him and learn about this container's data structure, its key design elements and how it compares with other top-performance C++ hashmaps both in theory and in practice.

From the talk:

Boost 1.81 (Dec 2022) released boost::unordered_flat_map, a hashmap (unordered associative container in C++ parlance) that relies on open addressing and SIMD techniques to provide extremely high performance. In this talk, Joaquín will invite you to look under boost::unordered_flat_map's hood with him and learn about this container's data structure, its key design elements and how it compares with other top-performance C++ hashmaps both in theory and in practice. The talk finishes with a teaser on concurrent hashmaps arriving as part of your Boost update later this year. Deck and note can be found here
