TK1入门教程软件篇-安装CUDA

说明：

• 介绍如何在TK1上安装CUDA

步骤：

• 下载.deb软件包：

http://developer.download.nvidia.com/embedded/L4T/r21_Release_v3.0/cuda-repo-l4t-r21.3-6-5-prod_6.5-42_armhf.deb

• 在TK1上，安装.deb软件包

cd ~/Downloads  
sudo dpkg -i cuda-repo-l4t-r21.3-6-5-prod_6.5-42_armhf.deb  
sudo apt-get update  
sudo apt-get install cuda-toolkit-6-5  
sudo usermod -a -G video $USER

• 配置到.bashrc

echo "# Add CUDA bin & library paths:" >> ~/.bashrc  
echo "export PATH=/usr/local/cuda/bin:$PATH" >> ~/.bashrc  
echo "export LD_LIBRARY_PATH=/usr/local/cuda/lib:$LD_LIBRARY_PATH" >> ~/.bashrc  

• 启用新环境变量

source ~/.bashrc

• 验证

nvcc -V  

安装CUDA例子：

• 安装例子到用户的根目录：

cuda-install-samples-6.5.sh /home/ubuntu

• 编译例子：

cd ~/NVIDIA_CUDA-6.5_Samples
make

• 运行例子：

1_Utilities/deviceQuery/deviceQuery
1_Utilities/bandwidthTest/bandwidthTest

cd 0_Simple/matrixMul
./matrixMulCUBLAS
cd ../..

cd 0_Simple/simpleTexture
./simpleTexture
cd ../..

cd 3_Imaging/convolutionSeparable
./convolutionSeparable
cd ../..

cd 3_Imaging/convolutionTexture
./convolutionTexture
cd ../..

• CUDA的例子使用OpenGL GLX和图形界面，在SSH登录情况下，需要指定窗口export DISPLAY=:0
• 例如：

export DISPLAY=:0
cd ~/NVIDIA_CUDA-6.5_Samples/2_Graphics/simpleGL
./simpleGL

cd ~/NVIDIA_CUDA-6.5_Samples/3_Imaging/bicubicTexture
./bicubicTexture

cd ~/NVIDIA_CUDA-6.5_Samples/3_Imaging/bilateralFilter
./bilateralFilter
