ZLUDA

ZLUDA is described by its README as a drop-in replacement for CUDA on non-NVIDIA GPUs. To unpack that, CUDA is software made by NVIDIA that lets programs run heavy calculations on NVIDIA graphics cards, which is common in areas like machine learning, scientific computing, and video processing. Normally a program written for CUDA only runs on NVIDIA hardware.

The goal of ZLUDA is to remove that restriction. The README states that it allows running unmodified CUDA applications on graphics cards from other makers, and that it aims to do so with near-native performance. Near-native means the speed is meant to be close to what you would get on the NVIDIA hardware the program was originally written for. The phrase 'unmodified' matters here: the idea is that you do not need to rewrite the application, you point it at ZLUDA and it runs on the different GPU.

The project is written in Rust, a programming language often chosen for low-level work where performance and reliability are important. That fits the kind of task ZLUDA takes on, since it sits between an application and the graphics hardware.

The README itself is very short. It gives the one-line summary above and then links out to a quick start guide, a Discord community, and a news page, without explaining installation, supported hardware, or limitations in the text provided here. Anyone wanting those details would need to follow the linked documentation. So this page tells you clearly what ZLUDA is trying to do, but the practical specifics of how to set it up and which GPUs it covers live outside this README.
