  • OpenBLAS

    OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version.

    • Project mention: LLaMA Now Goes Faster on CPUs | news.ycombinator.com | 2024-03-31

    The Fortran implementation is just a reference implementation. The goal of reference BLAS [0] is to provide relatively simple and easy to understand implementations which demonstrate the interface and are intended to give correct results to test against. Perhaps an exceptional Fortran compiler which doesn't yet exist could generate code which rivals hand (or automatically) tuned optimized BLAS libraries like OpenBLAS [1], MKL [2], ATLAS [3], and those based on BLIS [4], but in practice this is not observed.

    Justine observed that the threading model for LLaMA makes it impractical to integrate one of these optimized BLAS libraries, so she wrote her own hand-tuned implementations following the same principles they use.

  • HandmadeMath

    A simple math library for games and computer graphics. Compatible with both C and C++. Public domain and easy to modify.

    • Project mention: Trouble calculating projection matrix | /r/GraphicsProgramming | 2023-06-20

    If you don't like using heavy libraries such as glm, I recommend looking at HandmadeMath. It is a single file c/c++ math library for graphics programming. You can just drop it into your project. It's lightweight and will save you a lot of time implementing the math yourself. In a lot of cases, it actually uses optimized solutions to save computation time (same with the glm).
