John "God" Carmack: C++ with a C flavor is still the best (also: Python performance "keeps hitting me in the face")

• libCat

  21 58 7.1 C++

  🐈‍⬛ A runtime for C++26 w/out libC or POSIX. Smaller binaries, only arena allocators, SIMD, stronger type safety than STL, and value-based errors!

I'm working on this! https://github.com/Cons-Cat/LibCat

• Vc

  6 1,417 6.1 C++

  SIMD Vector Classes for C++

  

I personally like the ideas in Parallelism v2 TS, which is available in for libstdc++ 11 onwards. The reference implementation is a library named Vc (afaik Vc is the most popular SIMD library for C++), and this has also been implemented in recent versions of HPX.

  The C++ Standard Library for Parallelism and Concurrency

• highway

  66 3,623 9.8 C++

  Performance-portable, length-agnostic SIMD with runtime dispatch

  

I haven't used Google's library Highway, which afaik has all of the same benefits. It's just that the Vc-style code will presumably be part of the STL in the future. I'm surprised it wasn't in C++23.

  DOOM Open Source Release
