Top 7 C++ simd-instruction Projects

  • highway

    Performance-portable, length-agnostic SIMD with runtime dispatch

    Project mention: Gemma.cpp: lightweight, standalone C++ inference engine for Gemma models | news.ycombinator.com | 2024-02-23

    Thanks so much!

    Everyone working on this self-selected into contributing, so I think of it less as my team than ... a team?

    Specifically want to call out: Jan Wassenberg (author of https://github.com/google/highway) and I started gemma.cpp as a small project just a few months ago + Phil Culliton, Dan Zheng, and Paul Chang + of course the GDM Gemma team.

    I wonder how much of the performance will improve when compilers get better at RISC-V.

    It's been a long time since I could beat the compiler at optimizing assembly on x86, yet in the end merely unrolling a loop and keeping an eye on write-read stalls I managed to get a simple "multiply array by const" about 56% faster:


    And that's with hardware that doesn't even have vector instructions! I'd understand GCC not supporting that yet.

    Some other quickstart docs and hot takes from me on this hardware: https://blog.habets.se/2023/01/VisionFive-2-quickstart.html
