xsimd
C++ wrappers for SIMD intrinsics and parallelized, optimized mathematical functions (SSE, AVX, AVX512, NEON, SVE))
Thanks, that's an important caveat!
> Meanwhile xsimd (https://github.com/xtensor-stack/xsimd) has the feature level as a template parameter on its vector objects
That's pretty cool because you can write function templates and instantiate different versions that you can select at runtime!

Simd
C++ image processing and machine learning library with using of SIMD: SSE, AVX, AVX-512, AMX for x86/x64, NEON for ARM. (by ermig1979)

Project mention: Understanding SIMD: Infinite Complexity of Trivial Problems | news.ycombinator.com | 2024-11-30
I'm surprised no one has mentioned Vc. I found ispc clunky and not as performant, and std::simd didn't support some useful math ops like rsqrt. Vc has been around for years, I have no trouble including it in my codes, it has masking and many of the most useful math ops, and I can get over 1 TF/s on a consumer-grade Ryzen and at least 3 TF/s on the big Epyc CPUs.
