Does anyone know any good open source project to optimize?

• xtensor

  8 3,205 7.9 C++

  C++ tensors with broadcasting and lazy computing

  

• quaternion

  3 591 7.0 Python

  Add built-in support for quaternions to numpy (by moble)

numpy-quaternion is a neat little C extension for Python that adds support for quaternions to NumPy. I haven't seen it use SIMD or GPGPU in a quick look through its source.

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• Box2D

  35 7,280 0.0 C++

  Box2D is a 2D physics engine for games

I suspect most C++ physics libraries like Box2D (https://github.com/erincatto/box2d) or Bullet3 (https://github.com/bulletphysics/bullet3) could really benefit a lot from SIMD.

• Bullet

  41 11,907 4.5 C++

  Bullet Physics SDK: real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc.

• MLV-App

  7 265 8.8 C++

  All in one MLV processing app.

• Project-Alice

  An open-source game

Currently I am part of a team working on an open source game (https://github.com/schombert/Project-Alice) that intends to lean heavily on vectorization for performance, since it is a strategy game that has to work with a decently large amount of data, by the standards of a game at least. We have things set up so that most of the data is stored in something like the struct of arrays pattern and we have some machinery in place for doing vectorized operations on it. But obviously we could benefit from a specialist. On the other hand, perhaps a game is not serious enough for your work, and there is a lot of things going on in a game that are probably irrelevant for your work.

• HPX

  15 2,417 9.8 C++

  The C++ Standard Library for Parallelism and Concurrency

  

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
