CUDA 10.2 インストール2020/07/21 |
|
NVIDIA 社製グラフィックカードによる GPU コンピューティング GPGPU（General-Purpose computing on Graphics Processing Units) プラットフォーム CUDA (Compute Unified Device Architecture)
をインストールします。
CUDA を利用するにあたっては、グラフィックカードが対応製品である必要があります。詳細は NVIDIA 社のサイトで確認ください。(ここ数年のものであればほぼ対応) ⇒ https://developer.nvidia.com/cuda-gpus |
