CUDA 10.1 : Install2020/07/27 |
|
Install GPU Computing Platform (GPGPU (General-Purpose computing on Graphics Processing Units)), CUDA (Compute Unified Device Architecture) provided by NVIDIA.
To use CUDA, it needs your computer has NVIDIA Graphic cards and also they are the CUDA-Enabled products.
Make sure the details on the site below. (most products are ready in the past few years) ⇒ https://developer.nvidia.com/cuda-gpus |
