安装beignet以在Intel上使用OpenCL,但OpenCL程序仅在以root身份运行时才能运行

标签: python opencl gpu intel gpgpu

我有一台Intel HD graphics 4000第三代处理器,我的操作系统是Linux Mint 17.1 64位。我安装了beignet以便能够使用OpenCL,从而在GPU上运行程序。我使用pyOpenCL绑定遇到了很多问题,所以我决定卸载我当前的beignet版本并安装最新的版本(你可以看到我之前提出的问题并自己回答了问题{ {3}})。

升级beignet工作正常,我现在可以通过OpenCLpython绑定在我的GPU上运行C/C++代码。但是,我只能以root身份运行程序,否则它们不会将我的GPU检测为有效设备。

程序工作,这很棒,但现在我正试图解决以root身份运行所有内容的烦恼。

当我不以root身份运行它们时,我收到以下错误:

/dev/dri/card0 not authenticated
Device open failed, aborting...
/dev/dri/card0 not authenticated
Device open failed, aborting...
cl_get_gt_device(): error, unknown device: ffffffff

当我以root身份运行它们时,它们工作,但首先它们会显示以下消息:

modprobe: FATAL: Module nvidia not found.

我尝试sudo apt-get purge nvidia*但由于某种原因,也卸载了pyOpenCL,当然我的python程序停止了工作。我还在这里找到了一个答案,建议检查/dev/nvidia*/文件夹的权限,但它在我的计算机中不存在。

提前致谢。

编辑:添加一些请求的输出。

我知道这有点复活旧帖,但我最近解决了这个问题并且没有找到任何在线发布的解决方案,所以这里有......

使用最新的内核默认情况下启用了rnodes,但这仍然无效...下一步是检查/ dev / dri文件的所有权... 例如在我的系统上,我得到:

$ ls -l /dev/dri
total 0
crw-rw---- 1 root video 226,   0 May 16 21:30 card0
crw-rw---- 1 root video 226,  64 May 16 21:30 controlD64
crw-rw---- 1 root video 226, 128 May 16 21:30 renderD128

提示我要么是root用户,要么是"视频"的成员。组访问设备......

将相关用户(即您想要运行opencl程序的用户)添加到组中:

usermod -a -G video <user>

然后relog和bingo不再需要以root身份运行了!

答案 1 :(得分:2)

我不是beignet的专家,但我知道关于直接渲染的一两件事,所以这是我可以提取的阅读一些文档。

beignet支持三种模式:

  1. 使用root直接连接到设备(这就是您正在做的事情
  2. 使用dri2作为普通用户通过X服务器进行连接
  3. 直接在直接渲染节点上将设备用作普通用户
  4. 在进一步之前,您需要检查视频卡驱动程序以及运行脚本的环境中是否启用了直接呈现。这是通过您运行脚本的同一终端中的以下命令完成的:

    glxinfo | grep render
    

    它应输出类似Direct rendering: yes的内容,这很棒。 glxinfo为您提供了有助于查找问题根源的所有其他信息,因此请务必使用命令的完整输出更新您的问题(不使用{{1}部分)。

    方法2 是使用直接呈现的最简单方法,但要求运行脚本的环境具有| grep direct变量设置。如果您在终端模拟器(如Mint中的终端应用程序)上运行它,则应该已经设置了它。您可以通过输入以下命令来检查:

    DISPLAY

    它应该打印echo $DISPLAY 或类似的东西。如果它没有显示任何内容,那么您的脚本不知道要渲染到哪个屏幕(或视频卡)。如果您通过SSH在远程计算机上工作,或者在没有桌面环境的情况下直接使用终端屏幕,则可能会发生这种情况。您当然可以使用以下命令设置此变量:

    :0

    您只需要确定要呈现的正确显示(运行X服务器的那个),您可以检查glxinfo的输出。

    方法3 要求您的视频卡支持KVM(显然它支持KVM)并启用渲染节点。这是在系统启动时完成的,因此您需要修改引导加载程序参数以启用它。如果你使用GRUB2启动,这很简单(但是,你知道,如果出现任何问题,请备份任何重要的事情):

    以root身份,您必须编辑文件export DISPLAY=:0 并查找以下行(...是因为它可以包含的参数多于这两个参数):

    /etc/defaults/grub

    然后,您必须添加在该变量末尾启用渲染节点的参数:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash …"
    

    之后,保存文件并以root身份执行以下命令:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash … drm.rnodes=1"
    

    然后重新启动计算机,您的脚本应该以普通用户身份运行。

    更新关于您以root用户身份运行的NVIDIA错误,您的笔记本电脑(因为它是笔记本电脑,对吧?)是否有混合显卡?如果是这样,那么你应该在正确的卡上运行OpenCL。请使用以下命令的输出更新您的问题:

    sudo update-grub
    

    那应该告诉我们你正在处理什么硬件。
