SIMD instructions with Rust on Android by Guillaume Endignoux – Rust Zürisee June 2023

SIMD instructions have become increasingly important to speed up algorithms, and Rust now exposes them as intrinsics in the standard library.
However, SIMD presents unique challenges, among others: portability, testability, usability, and making sure the compiler indeed generated optimized code.
In this talk, I’ll take the angle of using Rust on Android to discuss how to approach and solve these challenges.
