Hello,

got some of the OpenCL examples running with my onboard 3200. Now tried an 4870 from XFX but  the device is not known.

Any hints? Is there a BIOS Problem with XFX Branding?

Greetings,

Which operating system are you using? Also, could you post the exact error message you are getting?

OS: Ubuntu 9.04 x64.

It looks like my onboard HD 3200 made some problems.

When i connect the 4870 to the display the fglrx driver and opencl samples works fine.

(but i may not disable the onboard graphics in the BIOS, otherwise the fglrx driver will report some invalid BIOS messages)

Is it possible to run a 3200 and 4870 simultan. The little one for graphics and the big one for computation?

Greetings,

what you get when you run FindNumDevices from CAL samples? try then

export DISPLAY=:0

[smatovic]

I get only one device, that one which is configured in xorg.conf

Supported CAL Runtime Version: 1.3.185
Found CAL Runtime Version: 1.4.467
Use -? for help
CAL initialized.
Finding out number of devices :-
Device Count = 1
CAL shutdown successful.


export DISPLAY shows no effect.

I guess this is an dirver or xorg issue becouse lspci tells me there are two devices:

01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200 Graphics
02:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4870]


nevertheless, i am glad to see the 4870 running opencl code
