Missing opencl support

Opencl cannot find cards

I have just gotten my new computer with 2 firepro v7800 cards.  I installed the unified driver for the firepro and the AMD app sdk.  I then started up the examples and the examples were unable to find the graphics card.  I tried uninstalling everything, and reinstalling and once again OpenCL was unable to find my card. 

 

What am I missing?

Same story here:

The machine I'm working on is running  Ubuntu-server 10.04.1 LTS (64 bit)

The driver installed is ATI FirePro Software Suite Multilanguage 8.83.5.4

aticonfig --lsa returns:

* 0. 03:00.0 ATI FirePro V4800 (FireGL)

Which is indeed the correct card.

 

When running clinfo from AMD-APP-SDK-v2.4, only 1 device is detected: the CPU. The GPU is not detected.

OK, I was able to make it work.

I installed xubuntu-desktop. After logging in in  the desktop, clinfo detected the GPU (even when run in an ssh session).

When not logged in in the desktop, clinfo only detects the CPU.

Sounds right. The GPU driver is started when X comes up - if you are running without X then the OpenCL runtime won't be able to find the GPU.

Is there a way to start the driver without running X? This would be useful when developing for server platforms.
