Hacker News with Generative AI: SIMD

Expressive Vector Engine – SIMD in C++ (github.com/jfalcou)
EVE is a re-implementation of the old EVE SIMD library by Falcou et al. which for a while was named Boost.SIMD. It's a C++20 and onward implementation of a type based wrapper around SIMD extensions sets for most current architectures. It aims at showing how C++20 can be used to design and implement efficient, low level, high abstraction library suited for high performance.

RISC-V Vector Extension overview (0x80.pl)
The goal of this text is to provide an overview of RISC-V Vector extension (RVV), and compare — when applicable — with widespread SIMD vector instruction sets: SSE, AVX, AVX-512, ARM Neon and SVE.

A not so fast implementation of cosine similarity in C++ and SIMD (joseprupi.github.io)
There isn’t much to see here, just me dusting off some old architecture knowledge to parallelize computations using SIMD, implement it in C++, and compare the results with Python.
