Post date: 2015/04/26 6:43:00

cuda7.0が出たが，GT240の最新版ドライバがR340のため，cuda6.5をインストール

  1. ubuntu14.04 用 cuda_6.5.14_linux_64.run をダウンロード
  2. コンソールモードでX停止
      • $ sudo service stop lightdm $ sudo init 3
  3. 古いパッケージを削除
      • $ sudo apt-get --purge remove nvidia-* $ sudo apt-get --purge remove cuda-*
  4. cuda 6.5 install
      • $ sudo sh ./cuda_6.5.14_linux_64.run
  5. 動作テスト
      • $ ./startx
      • $ cat /proc/driver/nvidia/version
      • NVRM version: NVIDIA UNIX x86_64 Kernel Module 340.29
      • Thu Jul 31 20:23:19 PDT 2014
      • GCC version: gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1)
  6. 再起動
      • $ sudo reboot
  7. デバイス確認
      • $ cd ~/NVIDIA_CUDA-6.5_Samples/1_Utilities/deviceQuery
      • $ make
      • $ ./deviceQuery

      • Result = PASS

注意点:

  • installer 用 cuda-repo-ubuntu1404_6.5-14_amd64.deb ファイルは PGP キー取得でエラーを起こす
  • cuda-7.0 は nvidia-346 が必要
  • sm_1.1, 1.2(GT240), 1.3 は近々外される模様(既にcuda-7.0 はdriverが無い)
  • cusp-library-0.5.0 の cg は sm_1.2 には対応せず
