本文介绍了已安装beignet以在Intel上使用OpenCL，但是OpenCL程序仅在以root身份运行时才能工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个Intel HD图形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版本并安装最新的版本(您可以看到我问过的上一个问题，并对此得到了回答).
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).
升级beignet成功，现在我可以通过python和C/C++绑定在我的GPU上运行OpenCL代码.但是，我只能以root用户身份运行程序，否则它们不会将我的GPU检测为有效设备.
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.
程序工作很棒，但是现在我试图解决必须以root用户身份运行所有程序的烦恼.
The programs work, which is great, but now I'm trying to solve the annoyance of having to run everything as root.
当我不以root用户身份运行它们时，会出现以下错误:
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
当我以root用户身份运行它们时，它们工作，但首先它们显示以下消息:
When I run them as root, they work, but first they show the following message:
modprobe: FATAL: Module nvidia not found.
我尝试了sudo apt-get purge nvidia*，但是由于某些原因，它也卸载了pyOpenCL，当然我的python程序也停止了工作.我还在这里找到答案，建议检查/dev/nvidia*/文件夹的权限，但是我的计算机中不存在该权限.
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.
谢谢.

推荐答案
我知道这有点像是在恢复旧线程，但是我最近解决了这个问题，还没有找到在线发布的任何解决方案，所以这里是...
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...
默认情况下，启用了最新内核rnodes，但这仍然行不通...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:
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
提示我需要成为root用户或视频"组的成员才能访问设备...
Hinting I either need to be root user or a member of the "video" group to access the device...
将相关用户(即您要运行opencl程序的用户)添加到组中:
Add the relevant user (i.e. the one you want to run the opencl program as) to the group:
usermod -a -G video <user>
然后重新记录日志和宾果游戏，无需再以root用户身份运行！
Then relog and bingo no need to run as root anymore!
这篇关于已安装beignet以在Intel上使用OpenCL，但是OpenCL程序仅在以root身份运行时才能工作的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
