Episode description

Speed and software should go hand in hand, but with Moore's Law coming to an end and CPU clock speeds remaining steady over the last 20 years, software engineers need to turn to new techniques to improve the efficiency of their code. In this episode, Matt and Angelica and joined by Clement Jean to discuss one of these techniques: SIMD. They'll discuss what SIMD is, how it can be used from languages like Go, the various proposals to get better support for SIMD directly into Go and its compiler, and a bunch of other related topics.
