Since updating to the newest version of BOINC, the GPU is no longer recognized by BOINC. I've reinstalled BOINC and made sure the current version of CUDA is installed. The top of the log is below.

Any suggestions as to what I need to do to make this work (again)?

Can you post the startup from the last version of Boinc you had installed? the first 20 to 30 lines will do.

Fri Apr 26 11:18:19 2013 | | Data directory: /Library/Application Support/BOINC Data

In the above directory should be two files called stdoutdae.txt and stdoutdae.old (or the OS X equivalent), eithier of those should have it.

Sure thing: this is the last restart of BOINC before the upgrade.

I've PM's Charlie Fenton, the Boinc OS X programmer and asked him to have a look.

BOINC currently does not support CUDA on dual-GPU MacBook Pros. This is because the way the CUDA drivers work, testing for the GPU's presence at BOINC startup causes the NVIDIA GPU to remain selected even when the computer is running on batteries, rapidly running down the battery. This happens even if BOINC suspends operation when running on battery power.

Testing for OpenCL does not have this problem, so we still support GPU computing using OpenCL on these computers. You will notice that your Event Log says:

Fri Apr 26 11:18:19 2013 | | BOINC does not support CUDA on this computer.
Fri Apr 26 11:18:19 2013 | | OpenCL: NVIDIA GPU 0: GeForce GT 650M (driver version CLH 1.0, device version OpenCL 1.1, 1024MB, 1024MB available, 29 GFLOPS peak)

I filed a bug report with NVIDIA on October 23, 2012. requesting a way to release the NVIDIA GPU so that it can switch back to the power-efficient integrated Intel GPU. Despite repeatedly contacting them, I am still waiting for them to do something about this. Because we have had so many complaints from users about BOINC running down their batteries, we have no choice but to disable CUDA support on MacBook Pros until NVIDIA provides a solution.

Cheers,

Tis a pity but such are manufacturers.

Many thanks,

These are the results in Mac OS X 10.6.8 Snow Leopard (and on 10.8.3 Mountain Lion)

CUDA driver 5.0.36 + BOINC 7.0.31 = Working fine (also works on Mountain Lion)
CUDA driver 5.0.45 + BOINC 7.0.31 = GPU missing (but works on Mountain Lion)
CUDA driver 5.0.36 + BOINC 7.0.65 = GPU missing (untested on Mountain Lion)
CUDA driver 5.0.45 + BOINC 7.0.65 = GPU missing (untested on Mountain Lion)

Pending a response from NVIDIA, can using CUDA become a configuration option anywhere? I'm now stuck on 7.0.31 since i want to continue using CUDA on my 2010 macbook pro.

Cheers, Andrew

CUDA driver is now up to 5.0.59, and is now 10.8.4. Any chance of a fix?

CUDA driver is now up to 5.0.59, and OS X is now 10.8.4. Any chance of a fix?

It would seem like OS X Mavericks Developer Preview 4 completely killed BOINC. CUDA drivers 5.0.61 refused to identify the GPU despite having BOINC Manager 7.0.31. Tried downgrading to versions 5.0.36 and 6.12 respectively, GPU is still missing...

Only on some machines:
My iMac 2012 (GTX680MX) is fine, my MacBook Pro 2012 (GT330M) is not. Doesn't appear to be a BOINC issue - Roxio Toast also looses CUDA.

Any word on this issue that has been plaguing me for several weeks? It is severely limiting my BOINC potential. CUDA is also now at version 5.5.25.

5.5.24 for me, still no luck in Mavericks... Still registered as GPU missing...

I just downgraded to 7.0.31 with no luck. Then I upgraded to CUDA 5.5.24 and voila! GPU processing for the first time in months.

This is on which version of OS X...?

10.8.4

Before upgrading to Mavericks, I had both a GT 120 and a GTX 570 crunching Einstein GPU units. When I upgraded to Mavericks, Boinc would only report the GTX 570, not the GT 120. I tried different versions of Boinc, and different CUDA versions, but the GT 120 would not show up.

Any ideas?

Since the CUDA drivers are built into OS X, it's not a BOINC problem, but rather one with your OS. Also proven by the fact that before you upgraded to your new OS, everything worked.

You can try to use a different driver. If your OS lets you.

I did try multiple earlier versions - none helped. In the event log, for all the cuds drivers I tried, there is no mention of the GT 120 at all.
