1) Message boards : Questions and problems : BOINC does not recognise ATI GPU on Mac OS X (Message 40302)

I'm in the same situation, BOINC Manager throws the following error in system.log when it launches:

9/16/11 12:33:16.868 PM boinc: [CL_INVALID_OPERATION] : OpenCL Error : Failed to retrieve device information! Invalid enumerated value!

To help us diagnose this, please answer a few questions:
• What model Mac?
• What version of the OS?
• What make and model GPU?

Thanks.

Do these people run their BOINC client as daemon? If so, tell them to stop doing so. Running as daemon will on all platforms (but for Windows XP) stop BOINC from detecting the GPU.

Furthermore, have them read and follow http://boinc.berkeley.edu/wiki/GPU_computing. Do they have the correct drivers installed?


Hi,

it is my machine that is linked in the original post by Ian.
I read through the link you posted but I am not sure if my BOINC client runs as deamon or not. After reading http://boinc.berkeley.edu/wiki/Tools_for_Mac_OS_X I would presume it is not since I am not using the Make_BOINC_Service.sh script. I am just using the standard installation. Unlike for Windows there was no option to enable/disable protected mode during the installation.

There is also no other project with ATI support for OSX to test and there is no separate ATI driver available for OSX. Unfortunately AMD doesn't list any drivers for OSX on their website. The driver that ships with OSX Lion (10.7) should be the latest version available.

Thanks,
Phil
