"AMD's ROCm Enables Unmodified CUDA Code Execution on Radeon GPUs"

TL;DR
ZLUDA, a project funded by AMD, enables unmodified CUDA code to run on AMD Radeon GPUs, allowing native CUDA applications to run on AMD hardware with near-native performance. Despite AMD discontinuing its support for the project, ZLUDA has been released as open-source software. While ZLUDA cannot run Nvidia Optix code, it has shown improved performance over AMD's Radeon HIP code in various applications. The developer plans to continue working on ZLUDA, focusing on personal interests without financial backing from AMD.
