ZLUDA Making Progress In 2025 On Bringing CUDA To Non-NVIDIA GPUs
The ZLUDA open-source effort that started off a half-decade ago as a drop-in CUDA implementation for Intel GPUs and then for several years was funded by AMD as a CUDA implementation for Radeon GPUs atop ROCm and then open-sourced but then reverted has been continuing to push along a new path since last year
The ZLUDA open-source effort that started off a half-decade ago as a drop-in CUDA implementation for Intel GPUs and then for several years was funded by AMD as a CUDA implementation for Radeon GPUs atop ROCm and then open-sourced but then reverted has been continuing to push along a new path since last year. The Q2'2025 status update for ZLUDA was posted today where they shared they have now doubled in size: there are now two developers working full-time on the project. In addition to onboarding a second developer, ZLUDA has been dealing with ABI breaks in ROCm, continued efforts on ensuring bit-accurate execution across GPUs/drivers, improved logging, some progress on NVIDIA PhysX support, and more.
