适用于Linux的NVIDIA CUDA安装指南
Linux系统下的NVIDIA CUDA 安装指南
1.简介
CUDA®是NVIDIA发明的并行计算平台和编程模型。通过利用图形处理单元(GPU)的强大功能,它可以显着提高计算性能。

CUDA ®是由NVIDIA发明了一种并行计算平台和编程模型。它通过利用图形处理单元(GPU)的能力,可以显着提高计算性能。

CUDA的
开发考虑了几个设计目标:CUDA开发时考虑了几个设计目标:
为标准编程语言(如C)提供一小组扩展,可以直接实现并行算法。使用CUDA C / C ++,程序员可以专注于算法并行化的任务,而不是花时间在他们的实现上。
Support heterogeneous computation where applications use both the CPU and GPU. Serial portions of applications are run on the CPU, and parallel portions are offloaded to the GPU. As such, CUDA can be incrementally applied to existing applications. The CPU and GPU are treated as separate devices that have their own memory spaces. This configuration also allows simultaneous computation on the CPU and GPU without contention for memory resources.
为标准编程语言(如C)提供一小组扩展,使得能够直接实现并行算法。使用CUDA C / C ++,程序员可以专注于算法的并行化任务,而不是花时间在它们的实现上。
支持异构计算,其中应用程序使用CPU和GPU。应用程序的串行部分在CPU上运行,并且并行部分被卸载到GPU。因此,CUDA可以递增地应用于现有应用程序。CPU和GPU被视为具有自己的存储空间的单独设备。此配置还允许在CPU和GPU上同时计算,而不争用存储器资源。
CUDA-capable GPUs have hundreds of cores that can collectively run thousands of computing threads. These cores have shared resources including a register file and a shared memory. The on-chip shared memory allows parallel tasks running on these cores to share data without sending it over the system memory bus.
This guide will show you how to install and check the correct operation of the CUDA development tools.
支持CUDA的GPU具有数百个内核,可以共同运行数千个计算线程。这些核具有共享资源,包括寄存器文件和共享存储器。片上共享内存允许在这些内核上运行的并行任务共享数据,而不通过系统内存总线发送数据。
本指南将向您展示如何安装和检查CUDA开发工具的正确操作。

1.1. System Requirements系统要求
To use CUDA on your system, you will need the following installed:
1、CUDA-capable GPU
2、A supported version of Linux with a gcc compiler and toolchain
3、NVIDIA CUDA Toolkit (available at http://developer.nvidia.com/cuda-downloads)
要在系统上使用CUDA,您需要安装以下软件:
1、支持CUDA的GPU
2、支持的Linux版本,带有gcc编译器和工具链
3、NVIDIA CUDA工具包

The CUDA development environment relies on tight integration with the host development environment, including the host compiler and C runtime libraries, and is therefore only supported on distribution versions that have been qualified for this CUDA Toolkit release.
CUDA开发环境依赖于与主机开发环境(包括主机编译器和C运行时库)的紧密集成,因此仅支持已获得此CUDA Toolkit版本的发行版本。

在CUDA表1原生Linux发行版支持8.0

(仅列出了Ubuntu系统,其余的略去)

1.2。关于本文件
This document is intended for readers familiar with the Linux environment and the compilation of C programs from the command line. You do not need previous experience with CUDA or experience with parallel computation. Note: This guide covers installation only on systems with X Windows installed.
本文档供读者熟悉Linux环境和从命令行编译C程序。你不需要提前具备CUDA经验或并行计算经验。注意:本指南仅介绍安装X Windows的系统上的安装。
Note: Many commands in this document might require superuser privileges. On most distributions of Linux, this will require you to log in as root. For systems that have enabled the sudo package, use the sudo prefix for all necessary commands.
注:本文中的许多命令可能需要超级用户权限。在大多数Linux发行版上,这将要求您以root用户身份登录。对于已启用sudo包的系统,请对所有必要的命令使用sudo前缀。

2.Pre-installation Actions预安装操作
Some actions must be taken before the CUDA Toolkit and Driver can be installed on Linux:
要在系统上使用CUDA,您需要安装以下软件:

1,验证系统是否具有支持CUDA的GPU。
2,验证系统是否正在运行受支持的Linux版本。
3,确认系统已安装gcc。
4,验证系统是否安装了正确的内核头文件和开发包。
5,下载NVIDIA CUDA工具包。
6,处理冲突的安装方法。

1、验证系统是否具有支持CUDA的GPU.
2、验证系统是否正在运行受支持的Linux版本
3、验证系统已经安装了gcc
4、验证系统是否安装了正确的内核头和开发包
5、下载NVIDIA CUDA工具包
6、处理冲突的安装方法
Note: You can override the install-time prerequisite checks by running the installer with the -override flag.Remember that the prerequisites will still be required to use the NVIDIA CUDA Toolkit.
注意:您可以通过使用-override标志运行安装程序来覆盖安装时间先决条件检查。请记住,仍然需要先决条件才能使用NVIDIA CUDA工具包。

2.1. Verify You Have a CUDA-Capable GPU 验证您是否具有支持CUDA的GPU
To verify that your GPU is CUDA-capable, go to your distribution’s equivalent of System Properties, or, from the command line, enter:
要验证您的GPU是否支持CUDA,请转到您的分布的等效系统属性,或从命令行输入:
$ lspci | grep -i nvidia

If you do not see any settings, update the PCI hardware database that Linux maintains by entering update-pciids (generally found in /sbin) at the command line and rerun the previous lspci command.
如果没有看到任何设置,请通过输入更新Linux维护的PCI硬件数据库 update-pciids (一般见于 / sbin)在命令行并重新运行前一个 lspci 命令。
If your graphics card is from NVIDIA and it is listed in http://developer.nvidia.com/cuda-gpus, your GPU is CUDA-capable.
The Release Notes for the CUDA Toolkit also contain a list of supported products.
如果你的显卡是来自NVIDIA的,它列在http://developer.nvidia.com/cuda-gpus,你的GPU是支持CUDA的。
CUDA工具包的版本说明还包含支持的产品列表。

2.2. Verify You Have a Supported Version of Linux 验证您是否具有受支持的Linux版本
The CUDA Development Tools are only supported on some specific distributions of Linux. These are listed in the CUDA Toolkit release notes.
CUDA开发工具仅支持某些特定的Linux发行版。这些在CUDA工具包版本注释中列出。
To determine which distribution and release number you’re running, type the following at the command line:
要确定您正在运行的分配和发行版号,请在命令行中键入以下内容:

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

You should see output similar to the following, modified for your particular system:
您应该看到类似于以下的输出,为您的特定系统修改:

x86_64 Red Hat Enterprise Linux Workstation release 6.0 (Santiago)
The x86_64 line indicates you are running on a 64-bit system. The remainder gives information about your distribution.
x86_64表示您正在64位操作系统上运行。剩余部分提供有关分发的信息。

2.3. Verify the System Has gcc Installed 验证系统是否已安装gcc
The gcc compiler is required for development using the CUDA Toolkit. It is not required for running CUDA applications. It is generally installed as part of the Linux installation, and in most cases the version of gcc installed with a supported version of Linux will work correctly.
gcc编译器是使用CUDA Toolkit进行开发所必需的。运行CUDA应用程序不需要它。它通常作为Linux安装的一部分安装,在大多数情况下,使用受支持版本的Linux安装的gcc版本将正常工作。

要验证系统上安装的gcc版本,请在命令行上键入以下内容:

要验证系统上安装的gcc的版本,请在命令行中键入以下命令:
$ gcc –version

If an error message displays, you need to install the development tools from your Linux distribution or obtain a version of gcc and its accompanying toolchain from the Web.
如果显示错误消息,则需要从Linux发行版安装开发工具或获取版本gcc 和其伴随的工具链从Web。

2.4. Verify the System has the Correct Kernel Headers and Development Packages Installed 验证系统是否安装了正确的内核标头和开发包
The CUDA Driver requires that the kernel headers and development packages for the running version of the kernel be installed at the time of the driver installation, as well whenever the driver is rebuilt. For example, if your system is running kernel version 3.17.4-301, the 3.17.4-301 kernel headers and development packages must also be installed.
CUDA驱动程序要求在驱动程序安装时,以及在重新构建驱动程序时,安装运行版本内核的内核头文件和开发包。例如,如果您的系统运行的是内核版本3.17.4-301,则还必须安装3.17.4-301内核头文件和开发包。

While the Runfile installation performs no package validation, the RPM and Deb installations of the driver will make an attempt to install the kernel header and development packages if no version of these packages is currently installed.However, it will install the latest version of these packages, which may or may not match the version of the kernel your system is using.Therefore, it is best to manually ensure the correct version of the kernel headers and development packages are installed prior to installing the CUDA Drivers, as well as whenever you change the kernel version.
虽然Runfile安装不执行软件包验证,但如果当前未安装这些软件包的版本,驱动程序的RPM和Deb安装将尝试安装内核头文件和开发软件包。但是,它将安装这些软件包的最新版本,这可能与您的系统使用的内核版本不匹配。 因此,最好在安装CUDA驱动程序之前,以及每当更改内核版本时,手动确保安装正确版本的内核头文件和开发包。
可以通过运行以下命令找到系统运行的内核版本:
$ uname -r

This is the version of the kernel headers and development packages that must be installed prior to installing the CUDA Drivers.This command will be used multiple times below to specify the version of the packages to install.Note that below are the common-case scenarios for kernel usage.More advanced cases, such as custom kernel branches, should ensure that their kernel headers and sources match the kernel build they are running.
这是在安装CUDA驱动程序之前必须安装的内核头文件和开发包的版本。此命令将在下面多次使用,以指定要安装的软件包的版本。请注意,以下是内核使用的常见情况。更高级的情况,例如自定义内核分支,应该确保它们的内核头和源与它们正在运行的内核构建匹配。

RHEL/CentOS系统、Fedora系统、OpenSUSE/SLES系统 略

Ubuntu
The kernel headers and development packages for the currently running kernel can be installed with:
当前运行的内核的内核头文件和开发包可以安装:

s u d o a p t g e t i n s t a l l l i n u x h e a d e r s (uname -r)

Choose an Installation Method 选择安装方法
The CUDA Toolkit can be installed using either of two different installation mechanisms: distribution-specific packages, or a distribution-independent package.The distribution-independent package has the advantage of working across a wider set of Linux distributions, but does not update the distribution’s native package management system.The distribution-specific packages interface with the distribution’s native package management system.
CUDA工具包可以使用两种不同的安装机制安装:特定于发行版的包或与发行版无关的包。独立于分发的包具有跨越更广泛的Linux发行版的优点,但是不更新分发的本地包管理系统。特定于分发的包与分发的本地包管理系统接口。建议在可能的情况下使用特定于分发的软件包。

注意:不为x86_64版本以外的体系结构提供独立安装程序。对于本机以及交叉开发,必须使用特定于分发的安装程序安装工具包。有关更多详细信息,请参阅CUDA跨平台安装部分。

Download the NVIDIA CUDA Toolkit 下载NVIDIA CUDA工具包
NVIDIA CUDA工具包位于http://developer.nvidia.com/cuda-downloads

选择您正在使用的平台,并下载NVIDIA CUDA工具包。

The CUDA Toolkit contains the CUDA driver and tools needed to create, build and run a CUDA application as well as libraries, header files, CUDA samples source code, and other resources.
CUDA工具包包含创建,构建和运行CUDA应用程序所需的CUDA驱动程序和工具,以及库,头文件,CUDA示例源代码和其他资源。

下载验证
The download can be verified by comparing the MD5 checksum posted at http://developer.nvidia.com/cuda-downloads/checksums with that of the downloaded file.
下载可以通过比较发布的MD5校验核实http://developer.nvidia.com/cuda-downloads/checksums与下载文件。如果任一校验和不同,则下载的文件已损坏,需要重新下载。

要计算下载文件的MD5校验和,请运行以下命令:

$ md5sum

Handle Conflicting Installation Methods 处理冲突的方法
Before installing CUDA, any previously installations that could conflict should be uninstalled.This will not affect systems which have not had CUDA installed previously, or systems where the installation method has been preserved (RPM/Deb vs. Runfile).See the following charts for specifics.
在安装CUDA之前,应该卸载任何以前可能发生冲突的安装。这不会影响以前没有安装CUDA的系统,或者保留安装方法的系统(RPM / Deb vs. Runfile)。有关详细信息,请参阅以下图表。
这里写图片描述
使用以下命令卸载Toolkit runfile安装:

$ sudo /usr/local/cuda-XY/bin/uninstall_cuda_X.Y.pl

3. Package Manager Installation 软件包管理器安装
3.1Overview 概述
The Package Manager installation interfaces with your system’s package management system.When using RPM or Deb, the downloaded package is a repository package.Such a package only informs the package manager where to find the actual installation packages, but will not install them.
软件包管理器安装与系统软件包管理系统接口。当使用RPM或Deb时,下载的包是存储库包。这样的包只通知包管理器在哪里找到实际的安装包,但不会安装它们。
If those packages are available in an online repository, they will be automatically downloaded in a later step.Otherwise, the repository package also installs a local repository containing the installation packages on the system.Whether the repository is available online or installed locally, the installation procedure is identical and made of several steps.
如果这些软件包在联机存储库中可用,它们将在以后的步骤中自动下载。否则,存储库包还会在系统上安装包含安装包的本地存储库。无论存储库是联机可用还是本地安装,安装过程都是相同的,由几个步骤组成。
