Message 31373 - Posted: 5 Mar 2010, 23:34:33 UTC - in response to Message 30683.  

OK guys....

I'm running a 2009 MacBookPro (9400M and 9600M GT GPUs), running 10.6.2 (booted in 32 bits mode), CUDA 2.3.1a drivers and 2.3a toolkit. I created all links, cc_config.xml files or whatsoever tricks you may find on forums. I have tried all versions of BOINC, and now running 6.10.36.

Guess what "No usable GPU"....

How can that be ???? help !!!

I installed CUDA 3.01-beta, still no GPU seen. The issue seems to be with the CUDA installation, though it does not exhibit any error. I will try to recompile and keep you posted.

Does BOINC have appropriate rights in /dev ?

Well, there is no nv* device created in /dev on MacOS X.

There was an issue with the CUDA 3.01beta installer which had not replaced the Kernel Extension. I did it manually, still no change.

.... This is a CUDA issue for sure, just can't find how to solve it.

My Mac Pro with 8800 installed boots up and auto launches BOINC. When I upgraded to .36 and finally got the CUDA working (ya!) I noticed that the first launch after a reboot it won't see the GPU, but if I just quit, wait a few seconds and relaunch it, then BOINC will see it.

10.6.2. My machine

I have a MacPro with a gtx 285 that I bought only for Boinc.

So far, I still get the No usable GPUs found message.

Update boinc to 6.10.43, no more luck.
I installed CUDA 3.0Beta, same result.
Create a cc_config.xml file with <use_all_gpus>1</use_all_gpus> option - no luck.

any help would be appreciated.

Have you read this FAQ?
There's a section for MACs in it.

Thank you,

I started with 32 bits kernel and now the GPU is "found",
right now I use CUDA 3.0 - should I go back to 2.3 ?

if I understand correctly, project that support GPU on Mac are,
GPUGrid
Einstein@Home
Milkyway@Home
Collatz Conjecture

I will attach to all of them and see.
