veccore

1 79 4.8 C++

C++ Library for Portable SIMD Vectorization

Project mention: Optimization Example: Mandelbrot Set (part 1) | news.ycombinator.com | 2024-02-19

In VecCore (a small C++ SIMD abstraction library on top of Vc and std::simd), I created some simple examples to show how to use the library to optimize code using SIMD in a somewhat generic way. You can find it on GitHub at https://github.com/root-project/veccore
I have examples for Julia sets and the Mandelbrot set, including an implementation with AVX2 intrinsics.
These days with std::simd more widely available there's less of a reason to use VecCore, but the examples may still be educational enough.
