WebWriting cache-friendly code. Both those types of optimization can be of use, but there's one more important thing that you need to keep in mind when working on performant systems: cache friendliness. Using flat data structures instead of node-based ones means that you need to perform less pointer chasing at runtime, which helps your performance. WebFeb 1, 2024 · Quicksort is a cache-friendly algorithm as it has a good locality of reference when used for arrays. It is tail -recursive and hence all the call optimization can be done. It is an in-place sort that does not require any extra storage memory. It is used in operational research and event-driven simulation.

WebJun 5, 2024 · Many programmers think that writing cache friendly code is not something that they have to worry about and compilers do this job for them. Well, I don’t know how much and which segment of... WebSep 29, 2024 · If you somehow manage to transform in into exchange of cache lines or close to it then the code should be faster. So, if matrix rows memory are 64bit aligned then it should be most efficient to use tiled-like version with parameter 4 or 8. But at long as it is not aligned you'll surely get random results. – ALX23z Oct 27, 2024 at 4:27 Add a comment flight of the phoenix trivia
