Top 6 C Avx512 Projects

  • simde

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

    • Project mention: The Case of the Missing SIMD Code | news.ycombinator.com | 2023-06-08

    I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?

    I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

    SIMD Library for Evaluating Elementary Functions, vectorized libm and DFT

    I'm the main author of Highway, so I have some opinions :D Number of operations/platforms supported are important criteria.

    A hopefully unbiased commentary:

    Simde allows you to take existing nonportable intrinsics and get them to run on another platform. This is useful when you have a bunch of existing code and tight deadlines. The downside is less than optimal performance - a portable abstraction can be more efficient than forcing one platform to exactly match the semantics of another. Although a ton of effort has gone into Simde, sometimes it also resorts to autovectorization which may or may not work.

    Eigen and SLEEF are mostly math-focused projects that also have a portability layer. SLEEF is designed for C and thus has type suffixes which are rather verbose, see https://github.com/shibatch/sleef/blob/master/src/libm/sleef... But it offers a complete (more so than Highway's) libm.

  • nsimd

    • Project mention: Show HN: The fastest Turbo-Base64 now for Python | news.ycombinator.com | 2023-08-24

    ** Cython bindings for Turbo Base64 [1] **

    - 20-30x faster than the standard library

    - Benchmarks faster than any other C base64 library

    - Fastest implementation of AVX, AVX2, and AVX512 base64 encoding

    - No other dependencies
