安装了beignet以在英特尔上使用OpenCL，但OpenCL程序仅在以root身份运行时才有效(Installed beignet to use OpenCL on Intel, but OpenCL programs only work when run as root)

我有一台英特尔高清显卡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并从而在GPU上运行程序。我使用pyOpenCL绑定时遇到了很多问题，所以我只是决定卸载当前的beignet版本并安装最新的版本（你可以在这里看到我提出的问题并回答我自己的问题）。

升级beignet工作，我现在可以通过python和C/C++绑定在我的GPU上运行OpenCL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。

这些程序运行良好，但现在我试图解决不得不以root身份运行一切的烦恼。

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，它们可以工作，但是首先它们会显示以下消息：

modprobe: FATAL: Module nvidia not found.

我试过sudo apt-get purge nvidia*但由于某种原因，也卸载pyOpenCL ，当然我的Python程序停止工作。我还在这里找到了一个答案，建议检查/dev/nvidia*/文件夹的权限，但它不存在于我的电脑中。

提前致谢。

I have an Intel HD graphics 4000 3rd Gen Processor, and my OS is Linux Mint 17.1 64 bit. I installed beignet to be able to use OpenCL and thus run programs on the GPU. I had been having lots of problems using the pyOpenCL bindings, so I just decided to uninstall my current beignet version and install the latest one (You can see the previous question I asked and answered myself about it here).

Upgrading beignet worked and I can now run OpenCL code on my GPU through python and C/C++ bindings. However, I can only run the programs as root, otherwise they don't detect my GPU as a valid device.

The programs work, which is great, but now I'm trying to solve the annoyance of having to run everything as root.

When I don't run them as root, I get the following error:

/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

When I run them as root, they work, but first they show the following message:

modprobe: FATAL: Module nvidia not found.

I tried sudo apt-get purge nvidia* but for some reason that also uninstalled pyOpenCL and of course my python programs stopped working. I also found an answer here suggesting to check the permissions of the /dev/nvidia*/ folder, but it doesn't exist in my computer.

Thanks in advance.

EDIT: adding some requested outputs.

最满意答案

我知道这有点复活一个旧线程，但我最近解决了这个问题，并没有找到任何在线发布的解决方案，所以这里...

使用最新的内核默认情况下启用了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

暗示我或者需要成为root用户或“视频”组的成员才能访问设备......

将相关用户（即您想运行opencl程序的用户）添加到组中：

usermod -a -G video <user>

然后relog和宾果不再需要以root身份运行！

I know this is kinda resurrecting an old thread, but I recently solved this problem and haven't found any solutions posted online, so here goes...

With the latest kernels rnodes is enabled by default, but this still doesn't work... Next step is to check the ownership of the /dev/dri files... e.g. on my system, I get:

$ 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

Hinting I either need to be root user or a member of the "video" group to access the device...

Add the relevant user (i.e. the one you want to run the opencl program as) to the group:

usermod -a -G video <user>

Then relog and bingo no need to run as root anymore!
