Re: Guide to run OpenCL headless, without X server and as normal user

I am running 14.04 server. So maybe there is difference.

Re: Guide to run OpenCL headless, without X server and as normal user

Same issue with Ubuntu 14.04 server (clean install).

I used the pre-built packages from here (Installed the Dev files, and the Non-X support driver, and extracted /etc/ati/amdpcsdb.default from the standard package):

http://support.amd.com/en-us/download/desktop?os=Ubuntu+x86+64

And still got the long hang for 2-3 minutes and eventual completion of clinfo in AMD APP SDK 2.9.

Which AMD APP SDK did you install?

Is anyone else really using AMD cards in a server/cluster environment? Should I try Red Had instead?

Re: Guide to run OpenCL headless, without X server and as normal user

I didn’t install SDK. I just manually extracted the examples to test them.

Re: Guide to run OpenCL headless, without X server and as normal user

Just to chime in here:

I've got the latest Catalyst drivers installed and clinfo will show GPU device on a local X. However, through ssh as a normal user, clinfo gives the error

No protocol specified

No protocol specified

Error: No root privilege. Please check with the system-admin.

No protocol specified

No protocol specified

If I then run clinfo as sudo I get

No protocol specified

No protocol specified

No protocol specified

No protocol specified

In both cases, no GPU device is shown I've changed the permissions in /dev/ati. This is on Ubuntu 14.04 with no AMD SDK.

Any help would be much appreciated! (AMD making this stuff just work would be even more appreciated ).

Just want to let you know driver engineers are digging into this. If/when we get something solid, we'll post it here.

Just to be clear, headless = no X, no DISPLAY, etc.

Re: Guide to run OpenCL headless, without X server and as normal user

Hi All,

Since this guide is no more relevant as from catalyst 14.12 omega it is supported to run OpenCL applications without

X server.

     I request, some one please share the steps to start Opencl development on AMD APU 7850K based systems.

      Which drivers and SDKs do I need to install so that I can use the 7850K without X server and program in OpenCL.

      Thanks in advance.

Regards,

Ameet
