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. https://github.com/VcDevel/Vc https://github.com/VcDevel/Vc https://github.com/Applied-Scientific-Research/nvortexVc https://github.com/Applied-Scientific-Research/nvortexVc
