Top 5 C sse2 Projects

  1. simde

    Implementations of SIMD instruction sets for systems which don't natively support them.

    Project mention: FFmpeg School of Assembly Language | news.ycombinator.com | 2025-02-22

    You can use https://github.com/simd-everywhere/simde if you like. In general portable SIMD libraries are of limited utility because having different primitives available on different architectures means that you should approach problems differently. That is to say, in many cases using any portable SIMD API to solve your problem means leaving 200% speedups on the table on at least one of your top 3 targets.

  2. InfluxDB

  3. TurboPFor

    Fastest Integer Compression

  4. sleef

    SIMD Library for Evaluating Elementary Functions, vectorized libm and DFT

    You can always get more accuracy by expanding those 3 lines to handle more of the Taylor components… but it’s important to remember that this is still educational material.

    You can find more complete examples in my SimSIMD (https://github.com/ashvardanian/SimSIMD), but they also often assume that at a certain part of a kernel, a floating point number is guaranteed to be in a certain range. This can greatly simplify the implementation for kernels like Atan2. For general-purpose inputs, go to SLEEF (https://sleef.org). Just remember that every large, complicated optimization starts with a small example.

  5. nsimd

    Agenium Scale vectorization library for CPUs and GPUs

  6. TurboRLE

    TurboRLE-Fastest Run Length Encoding

  7. SaaSHub
