C is not suited to SIMD (2019)
(vmchale.com)
C (C++) is used to write performant software, however it is ill-suited to SIMD. In particular, its compilation of stepped reduction with lexical scoping opposes parallel execution.

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

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.

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.
