Gdev is open-source software providing first-class GPU resource management in the operating system and the runtime driver. Currently NVIDIA GPUs and CUDA are primarily supported, but we plan to extend Gdev for other GPUs and programing languages. If you are interested in the development of Gdev, please contact us! This project is managed by PDSL at Nagoya University, Japan. Wish someday NVIDIA would open-source the device driver and the runtime!
