Step 2: Make sure your machine supports CUDA

The following machines support CUDA

NVIDIA GeForce 8, 9,200,400, and 500 series GPUs

NVIDIA TeslaTM computing solutions

Category of the NVIDIA Quadro products

Run the command to bring up the dialog box:

$ Nvidia-settings

NOTE: If your machine does not display a dialog box similar to the preceding one after running the nvidia-settings command, it means that you have not correctly installed the nvidia driver. See my article Ubuntu 11.10 ultimate solution for nvidia graphics Driver Installation: http://www.linuxidc.com/Linux/2012-04/58914.htm

Step 2: Install CUDA Toolkit

Download to the address below: http://developer.nvidia.com/cuda-toolkit

1) cudatoolkit_4.1.28_linux_64_ubuntu11.04.run

And

2) gpucomputingsdk_4.1.28_linux.run

Go to the directory of cudatoolkit_4.1.28_linux_64_ubuntu11.04.run and run the following command to install Toolkit:

$ Sudo sh./cudatoolkit_4.1.28_linux_64_ubuntu11.04.run

By default. Prompt that the installation is complete, set the environment variables, and execute the following two commands:

$ Export PATH =/usr/local/cuda/bin: $ PATH

$ ExportLD_LIBRARY_PATH =/usr/local/cuda/lib: $ LD_LIBRARY_PATH

In particular, if it is a 64-bit system, you need to add one more sentence:

$ ExportLD_LIBRARY_PATH =/usr/local/cuda/lib64: $ LD_LIBRARY_PATH

Of course, we can write the above command ~ /. In bashrc, environment variables are automatically added when the system starts.

$ Gedit ~ /. Bashrc

Add the following three sentences ~ /. Save the last part of bashrc and log out again.

Export PATH =/usr/local/cuda/bin: $ PATH

Export LD_LIBRARY_PATH =/usr/local/cuda/lib: $ LD_LIBRARY_PATH

ExportLD_LIBRARY_PATH =/usr/local/cuda/lib64: $ LD_LIBRARY_PATH

Verify installation:

Run $ nvcc-V to obtain the CUDAToolkit version to verify whether the installation is successful.

Nvcc: NVIDIA (R) Cudacompiler driver

Copyright (c) 2005-2011 NVIDIA Corporation

Built on Thu_Jan_12_14: 41: 45_PST_2012

Cuda compilation tools, release 4.1, V0.2.1221

Step 2: Install the GPU Computing SDK

For future development convenience, the SDK should not be installed as a root user. Run

$ Sh./cuda_installation/gpucomputingsdk_4.0.17_linux.run

Follow the prompts to complete the installation. Installed in the current user's Home by default.
