Cache-friendly binary search

“High-speed memory caches present in modern computer architectures favor data structures with good locality of reference, i.e. the property by which elements accessed in sequence are located in memory addresses close to each other. This is the rationale behind classes such as Boost.Container flat associative containers, that emulate the functionality of standard C++ node-based associative containers while storing the elements contiguously (and in order). This is an example of how binary search works in a boost::container::flat_set with elements 0 trough 30…”
