Top 8 C++ String Projects

StringZilla

14 1,829 9.8 C++

Up to 10x faster strings for C, C++, Python, Rust, and Swift, leveraging SWAR and SIMD on Arm Neon and x86 AVX2 & AVX-512-capable chips to accelerate search, sort, edit distances, alignment scores, etc 🦖

Project mention: Measuring energy usage: regular code vs. SIMD code | news.ycombinator.com | 2024-02-19

The 3.5x energy-efficiency gap between serial and SIMD code becomes even larger when
A. you do byte-level processing instead of float words;
B. you use embedded, IoT, and other low-energy devices.
A few years ago I've compared Nvidia Jetson Xavier (long before the Orin release), Intel-based MacBook Pro with Core i9, and AVX-512 capable CPUs on substring search benchmarks.
On Xavier one can quite easily disable/enable cores and reconfigure power usage. At peak I got to 4.2 GB/J which was an 8.3x improvement in inefficiency over LibC in substring search operations. The comparison table is still available in the older README: https://github.com/ashvardanian/StringZilla/tree/v2.0.2?tab=...
