SIMD in C++20: eve of a new era
summary
EVE is a C++20 SIMD library that provides a uniform API across ARM Neon and x86 (SSE2..AVX‑512) and shows working demos on Godbolt and slides. It offers STL-like algorithms and zip for multi-range ops, a broad math suite, and compile‑time dispatch via C++20 concepts. Benchmarks report about 10× speedup for a vectorized find on integers, up to 25× speedup for remove worst cases on chars, inclusive scan around 3–4×, and a deployed collect_indexes yielding >5× RPS.
