2.预安装
===========

2.1. Verify You Have a CUDA-Capable GPU::

    $ lspci | grep -i nvidia

2.2. Verify You Have a Supported Version of Linux::

    $ uname -m && cat /etc/*release

2.3. Verify the System Has gcc Installed::

    $ gcc --version

2.4. Verify the System has the Correct Kernel Headers and Development Packages Installed::

    $ uname -r

The kernel headers and development packages for the currently running kernel can be installed::
    
    RHEL/CentOS
    $ sudo yum install kernel-devel-$(uname -r) kernel-headers-$(uname -r)
    Ubuntu
    $ sudo apt-get install linux-headers-$(uname -r)

2.5. Choose an Installation Method::

    1. distribution-specific packages (RPM and Deb packages)
    2. distribution-independent package (runfile packages)
    可能的话建议使用第1种方法

2.6. Download the NVIDIA CUDA Toolkit::
