There seems to be a point at which an OS X host no longer receives new GPU tasks from Collatz; my MacBook Pro originally running 10.6 stopped receiving GPU tasks a while ago, and I just assumed that it was because the project was requiring a newer version of the GPU driver or system software. I recently upgraded to 10.8 (no clean install--same client ID) and noticed the same behavior as before; when the client requests GPU tasks, the only message returned from the project is "got 0 new tasks". I then completely reformatted and installed 10.8 on the MBP with a clean install of BOINC and have started receiving GPU tasks again.

Now, I've noticed that my iMac running 10.8 is no longer getting any GPU tasks... Just "got 0 new tasks". Any ideas as to why an OS X host seems to stop receiving GPU tasks from the project?

iMac 21.5" Mid 2011, Radeon HD 6750M 512 MB, OS X 10.8.4, BOINC 7.0.65
MacBook Pro 13" Mid 2010, GeForce 320M 256 MB, OS X 10.8.4 (formerly 10.6.8), BOINC 7.0.65

My Windows 7 host (formerly Vista) hasn't had any such problems, and has been crunching for a couple years now without a clean install or problems.

When you look at the BOINC log when it first starts up, does BOINC recognize that you have a GPU?

FYI, The 7.0.x versions are said to have scheduler bugs and I believe most of those will be fixed in the 7.2.x release that is almost ready for release. You could try using the BETA version v7.2.23 located at http://boinc.berkeley.edu/download_all.php.

7.2.28 seems to have cleared issues up for now... In fact, I'm getting GPU work from projects I hadn't before (Einstein)
