Top 9 C sorting-algorithm Projects

sorting-algorithms

  1. StringZilla

    Up to 10x faster strings for C, C++, Python, Rust, Swift & Go, leveraging NEON, AVX2, AVX-512, SVE, & SWAR to accelerate search, hashing, sort, edit distances, and memory ops 🦖

    Project mention: Counting Words at SIMD Speed | news.ycombinator.com | 2025-08-16

    You can avoid hard-coding the whitespace symbols and have a generic byte-set search kernel:

      - For AVX512VBMI-capable CPUs: https://github.com/ashvardanian/StringZilla/blob/2f4b1386ca2ed3c4178c1e4f467a2e78a911f3b2/include/stringzilla/stringzilla.h#L5657-L5769
