    Can not list R9 nano when running clinfo remotely

    FangQ

      (I apologize for posting this question here. I wanted to post it to the OpenCL forum, but I can not find "start a discussion" link! can anyone tell me how to post in that forum?)

       

      I am having trouble listing both of my AMD GPUs for OpenCL computing. The machine is a head-less server containing a Radeon 7970 and a R9 Nano. Initially, when I log on remotely (ssh or x2go), I was not able to see either of the cards. Then I found this online post and created at a script /tmp/enable-amd-compute, with a content of

       

      export COMPUTE=:0

      unset DISPLAY

      export XAUTHORITY=/tmp/x11-auth-file

       

      after running this script in every session, I am able to see 7970 in clinfo output. However, R9 nano is still not visible. I can only see both cards when using sudo clinfo, see

       

      fangq@pangucoe$ clinfo | grep "^\s*Name:"

        Name: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz

        Name: Tahiti

        Name: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz

       

      fangq@pangucoe$ sudo clinfo | grep "^\s*Name:"

        Name: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz

        Name: Tahiti

        Name: Fiji

        Name: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz

       

       

      Here are some additional info

       

      fangq@pangucoe$ sudo aticonfig --lsa

      * 0. 01:00.0 AMD Radeon R9 200 / HD 7900 Series

        1. 06:00.0 AMD Radeon (TM) R9 Fury Series

      * - Default adapter

       

      fangq@pangucoe$ ls -lt /dev/ati/

      total 0

      crw-rw-rw- 1 root amdgpu 246, 0 Aug 18 13:07 card0

       

      can anyone tell me how to use both cards without sudo? thanks
