WDDM is a driver model for GPU under Windows. By using WDDM, you can use it as a device to render your graphics as well as do some math calculating. The alternative one is TCC. By using TCC, it can be only used to do some calculations so that if you don’t have any other GPUs, you can not even boot up your machine. But your ML process won’t get interrupted so it’s great for HPC. Unfortunately, it is only available for Tesla and Quadro cards. Here are the details for the TCC mode: https://docs.nvidia.com/gameworks/content/developertools/desktop/nsight/tesla_compute_cluster.htm 34.
From what you posted, I don’t think there’s anything wrong there since it says Not available in WDDM driver model.
