TITAN Xを買ったので,CUDAをセットアップしてみる その2

TITAN Xを買ったので,CUDAをセットアップしてみる その1からの続き

6.CUDAのインストール

この時点でGUIが起動しないので,予め入れておいたSSHから入って作業を行う.

CUDAのダウンロードサイトからドライバを取ってくる.

今回はCUDA7.5をダウンロードした.1.9GB程度あるので暫し待つ.

wget http://developer.download.nvidia.com/compute/cuda/7.5/Prod/localinstallers/cuda-repo-ubuntu1404-7-5-local7.5-18_amd64.deb

sudo dpkg -i cuda-repo-ubuntu14047.5-18amd64.deb

sudo apt-get update

sudo apt-get install cuda

7.インストール後の状態を確認する

作業が粗いけどdeviceQueryしてみる

cd /usr/local/cuda-7.5/samples/1_Utilities/deviceQuery

sudo make

sudo ./deviceQuery

./deviceQuery Starting...
