安裝CUDA-8.0工具包在Debian8.8

Debian 8.8上安裝Nvidia驅動程式後，再來安裝CUDA toolkit。到官方網站上面下載：

1. Operation System選Linux
2. Architecture選x86_64
3. Distribution選Ubuntu（這邊沒有Debian可選，所以選從Debian改出來的Ubuntu）
4. Version選16.04
5. Installer Type選runfile (local)

測試過用deb套件安裝，但無法成功故在此採改成用runfile安裝。下載後會有兩個檔案：

• Base Installer：cuda_8.0.61_375.26_linux.run
• cuBLAS Patch 2：cuda_8.0.61.2_linux.run

上面是需要的檔案，以下是安裝步驟，請用root權限做

步驟1：安裝一些需要的東西

• apt-get install libxi libxi6 libxi-dev libglu1-mesa libglu1-mesa-dev libxmu6 libxmu6-dev

步驟2：用Base Installer安裝CUDA-8.0.61

• sh cuda_8.0.61_375.26_linux.run

      處理一堆選擇題，紅字是問題的答案：

1. Do you accept the previously read EULA?
   accept/decline/quit: accept
2. You are attempting to install on an unsupported configuration. Do you wish to continue?
   (y)es/(n)o [ default is no ]: y
3. Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 375.26?
   (y)es/(n)o/(q)uit: n
4. Install the CUDA 8.0 Toolkit?
   (y)es/(n)o/(q)uit: y
5. Enter Toolkit Location
   default is /usr/local/cuda-8.0 :/usr/local/cuda-8.0.61_375.26
6. Do you want to install a symbolic link at /usr/local/cuda?
   (y)es/(n)o/(q)uit: n
7. Install the CUDA 8.0 Samples?
   (y)es/(n)o/(q)uit: y
8. Enter CUDA Samples Location
   /usr/local/cuda-8.0.61_375.26

做完以後，去檢查下面兩的地方有沒有順利安裝：

• CUDA Toolkit：/usr/local/cuda-8.0.61_375.26
• CUDA samples：/usr/local/cuda-8.0.61_375.26/NVIDIA_CUDA-8.0_Samples

步驟3：安裝cuBLAS  Patch

• sh cuda_8.0.61.2_linux.run

      只要回答兩個問題，紅字是問題的答案：

1. Do you accept the previously read EULA?
   accept/decline/quit: accept
2. Enter CUDA Toolkit installation directory
   /usr/local/cuda-8.0.61_375.26

步驟4：新增檔案/etc/profile.d/cuda.sh

目的是要之後都找得到CUDA的執行檔與ld library，內容會是

export PATH=/usr/local/cuda-8.0.61_375.26/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0.61_375.26/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

步驟5：檢查是否安裝成功，用內附的samples來測試

首先登出後再度登入，然後執行下面指令安裝samples

1. cd /usr/local/cuda-8.0.61_375.26/NVIDIA_CUDA-8.0_Samples
2. make -j 16 2>&1 | tee make.log
3. cd /usr/local/cuda-8.0.61_375.26/NVIDIA_CUDA-8.0_Samples/bin/x86_64/linux/release
4. ./deviceQuery

如果有顯示安裝的顯示卡的資訊就代表是順利安裝～
