HI,

I have upgraded my OS to Mac Yosemite. Now all of my CUDA gPU WUs are not running.

From the log:

How do I fix this?

Thanks,

Does Yosemite have an (updated) Nvidia GPU driver with CUDA?
If not, see http://www.nvidia.com/download/driverResults.aspx/78853/en-us

Jord,

It was a good idea but the update is for Windows. Thanks for the answer as my chat with nVidia has pointed me in another direction.

??? that link I gave points for me to:

Quadro & GeForce Mac OS X Driver Release 343.01.01

Version: 343.01
Release Date: 2014.10.18
Operating System: Mac OS X Yosemite 10.10.0
Language: English (US)
File Size: 50.00 MB

You said in your first post that you upgraded to Yosemite and since that time had that problem, so I don't see where Windows gets into it.

Sorry...

That reference that you gave me was for MacPro machines. I have an iMac which is has a different architecture. My graphics card is an nVidia GTX 780M. I found a drive update for an nVidia GTX 780 which is for PCs with Windows.

I talked to nVidia and they stated that they do not have an updated driver for my card and they pointed me to the Apple Update app. Of course, that app doesn't have an update either. I suspect that in a future update to Yosemite for iMac it will just show up.

Have you try installing an older version of Cuda?

http://www.nvidia.com/object/macosx-cuda-6.5.18-driver.html

http://www.nvidia.com/object/macosx-cuda-6.0.51-driver.html

just a thought

One thing the developer pointed out to me: If you updated to CUDA 6.5, then do know that none of the present recommended BOINC versions will recognize your Nvidia GPU because the new drivers are 64bit only. Previous drivers may work on Yosemite, but perhaps also not.

Charlie Fenton, BOINC Developer for the Mac wrote:

Hi Jord,

If he has "upgraded" to CUDA driver 6.5.x, then current versions of BOINC won't recognize it because it is 64-bit only.

We were about to release a new version of BOINC with a 64-bit client which will recognize the new CUDA drivers, but found that it causes kernel panics (crashes the OS!), at least when used with older NVIDIA GPUs with compute capabilities less than 2.0. His GTX 780 should work fine with it, though; at least we hope so. We are working on getting a fix for this major issue before releasing a new BOINC for the Mac.

He can try downgrading to CUDA 6.0.51 or 6.0.54 in the meantime, but i don't know if they will work with Yosemite. I suspect they probably will, but have not tested it.

Cheers,
--Charlie

I am running on 6.5.18. I'll just wait for the BOINC update. I have de-CUDAed my programs.

Thanks for all the discussion and help.
