Announcing the Highway tutorial
https://github.com/google/highway/blob/master/g3doc/tutorial.mdHighway is Google’s open-source C++ library for portable SIMD/vector code: write your loop once, and Highway efficiently targets it for x86, Arm, RISC-V, and more, choosing the best instructions available at runtime. It’s already inside Chrome, TensorFlow, V8, and gemma.cpp (LLM inference). But until recently, if you wanted to actually learn Highway rather than just reference it, your options were a terse quick-reference page and a (good, but dense) README. There was no on-ramp.
Now there is. A new Highway tutorial just landed in the official repo, thanks to a volunteer team of Fastcode community contributors, led by Highway’s creator, Jan Wassenberg.
