  3. highway

    Performance-portable, length-agnostic SIMD with runtime dispatch

    Project mention: C++26 Shipped a SIMD Library Nobody Asked For | news.ycombinator.com | 2026-05-17

    People reported challenges building V8 (whether upstream or the Node.js variant) on s390x with z13 support. I don't know if it was discussed on the porters mailing list because it's not public: https://groups.google.com/g/v8-s390-ports

    Elsewhere, some people interpreted https://github.com/google/highway/issues/1895 as meaning that Highway code does not work on z13 at all.

  4. oneDNN

    oneAPI Deep Neural Network Library (oneDNN)

  5. xsimd

    C++ wrappers for SIMD intrinsics and parallelized, optimized mathematical functions (SSE, AVX, AVX512, NEON, SVE, WebAssembly, VSX, RISC-V))

    Project mention: xsimd: C++ Wrappers for SIMD Intrinsics | news.ycombinator.com | 2026-04-16

  6. Simd

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

  7. less_slow.cpp

    Playing around "Less Slow" coding practices in C++ 20, C, CUDA, PTX, & Assembly, from numerics & SIMD to coroutines, ranges, exception handling, networking and user-space IO

    Project mention: Processing Strings 109x Faster Than Nvidia on H100 | news.ycombinator.com | 2025-09-19

    Yes, at the scale of 128-bit registers NEON is mostly enough, except for a few categories of instructions missing in that ISA subset, like scatter/gather ops, that can yield 30% boost over serial memory accesses: https://github.com/ashvardanian/less_slow.cpp/releases/tag/v...

  8. kfr

    Fast, modern C++ DSP framework, FFT, Sample Rate Conversion, FIR/IIR/Biquad Filters (SSE, AVX, AVX-512, ARM NEON, RISC-V RVV)

    Project mention: Show HN: KFR 7 – major update for C++ DSP library | news.ycombinator.com | 2025-11-17

    Project mention: Eve: Expressive Vector Engine – SIMD in C++ Goes Brrrr | news.ycombinator.com | 2026-04-09

  11. libsimdpp

    Portable header-only C++ low level SIMD library

  12. primesieve

    🚀 Fast prime number generator

  13. x86-simd-sort

    C++ template library for high performance SIMD based sorting algorithms

  14. std-simd

    std::experimental::simd for GCC [ISO/IEC TS 19570:2018]

  15. toys

    Storage for my snippets, toy programs, etc.

  16. sse-popcount

    SIMD (SSE) population count --- http://0x80.pl/articles/sse-popcount.html

    Project mention: SIMD Population Count | news.ycombinator.com | 2026-04-16

  17. primecount

    🚀 Fast prime counting function library

  18. md5-optimisation

    The fastest MD5 implementation using x86 assembly

  19. ParallelReductionsBenchmark

    Thrust, CUB, TBB, AVX2, AVX-512, CUDA, OpenCL, OpenMP, Metal, and Rust - all it takes to sum a lot of numbers fast!

    Project mention: Fork Union: Beyond OpenMP in C++ and Rust? | news.ycombinator.com | 2025-09-28

    I was asked this a few months back but don’t have the measurements fresh anymore. In general, I think TBB is one of the more thorough and feature-rich parallelism libraries out there. That said, I just found a comparable usage example in my benchmarks, and it doesn’t look like TBB will have the same low-latency profile as Fork Union: https://github.com/ashvardanian/ParallelReductionsBenchmark/...

  20. Jsonifier

    A few classes for extremely fast json parsing/serializing in modern C++. Possibly the fastest json parser in C++. Possibly the fastest json serializer in C++. (by RealTimeChris)

  21. std_find_simd

    std::find simd version

  22. modernRX

    Modern C++ RandomX Implementation

  23. VectorizedKernel
