python - 安装了 beignet 以在 Intel 上使用 OpenCL,但 OpenCL 程序仅在以 root 身份运行时才有效

我有一个 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 并因此在 GPU 上运行程序。我在使用 pyOpenCL 绑定(bind)时遇到了很多问题,所以我决定卸载当前的 beignet 版本并安装最新版本(你可以看到我问的上一个问题并回答了我自己 here )。

升级 beignet 成功了,我现在可以通过 pythonC/C++ 在我的 GPU 上运行 OpenCL 代码绑定(bind)。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必须以 root 身份运行所有内容的烦恼。

当我不以 root 身份运行它们时,出现以下错误:

/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,但首先它们显示以下消息:

modprobe: FATAL: Module nvidia not found.

我尝试了 sudo apt-get purge nvidia* 但出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。

最佳答案

我知道这有点复活旧线程,但我最近解决了这个问题并且没有找到在线发布的任何解决方案,所以这里......

对于最新的内核,默认情况下启用 rnodes,但这仍然不起作用...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

提示我需要成为 root 用户或“video”组的成员才能访问设备...

将相关用户(即您希望运行 opencl 程序的用户)添加到组中:

usermod -a -G video <user>

然后重新登录和宾果游戏不再需要以 root 身份运行!

关于python - 安装了 beignet 以在 Intel 上使用 OpenCL,但 OpenCL 程序仅在以 root 身份运行时才有效,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/31901160/
