Dear Friends,

Welcome to the first newsletter for our ArrayFire community!

This newsletter brings together people using and developing ArrayFire and other accelerated computing tools. You are part of this vibrant group that “gathers” together around open source work, including:

  • Domain professionals – people who are experts in their disciplines doing serious heavy-lifting from research to production
  • Machine learning gurus – people who care about the best performance for training and inference
  • Hackers – people who love to contribute highly-optimized down-to-the-metal code

You are distinguished professionals in your domains, and we hope to build more opportunities for you to interact with the ArrayFire team and one another. We will start with this lightweight quarterly newsletter.

At a glance, you’ll be able to see recent developments as well as upcoming opportunities.


-John Melonakos, CEO & Co-Founder

Product Releases

ArrayFire v3.8.2 was released on May 19, 2022. Read more about it on the ArrayFire blog.

Project Spotlight:  Flashlight by Meta

Flashlight is a fast, flexible machine learning library written entirely in C++ from Facebook AI Research and the creators of Torch, TensorFlow, Eigen, and Deep Speech. Its core features include:

  • Total internal modifiability, including internal APIs for tensor computation
  • A small footprint, with the core clocking in at under 10 MB and 20k lines of C++
  • High-performance defaults featuring just-in-time kernel compilation with modern C++ via the ArrayFire tensor library
  • An emphasis on efficiency and scale

Native support in C++ and simple extensibility make Flashlight a powerful research framework that’s *hackable to its core* and enables fast iteration on new experimental setups and algorithms without sacrificing performance.

In a single repository, Flashlight provides apps for research across multiple domains:

Flashlight is fast, beating TensorFlow and PyTorch in 11 of 12 benchmarks (results available on arXiv).
