I have a problem which is starting to get extremely annoying involving GPU tasks. At the moment, i have BOINC set up to not run GPU or CPU tasks while the computer is in use. When i begin to use my computer, the CPU tasks always stop, but the GPU tasks keep going, in other words, Elapsed and Progress keep going, even though it says it's suspended.

I know i set everything correctly. Activity is set to "Run based on preferences" and "Use GPU based on preferences", so it shouldn't be doing that. The thing i do that will often make the GPU task stop is by switching "Run based on preferences" to "Run always" and back again. I'm running Mac OS X 10.6.5 on an '08 Aluminum MacBook. I'm only running one GPU task at the moment, and that's Collatz Conjecture, since none of the others last i checked will run on this computer.

In case you don't want to check yourself, the '08 MacBook comes with an Nvidia 9400m.

Which preferences are you using and updating?
The web-site preferences, or the local ones?

Is this BOINC 6.10.58?

It's BOINC 6.12.6, and i'm using local preferences. There should be no issues, but there clearly is.

It's BOINC 6.12.6, and i'm using local preferences. There should be no issues, but there clearly is.

I'm also running Boinc 6.12.6, with a 128Mb 8400M GS, similiar speed to your 9400m, but using Windows,
i'm also running Collatz GPU tasks, i've just tried out the 'Use GPU when computer is in use' local preference,
it does suspend here, BUT, the collatz GPU task does run until it reaches it's next checkpoint,
this takes up to 11 seconds, (unlike my 9800GTX+ and HD5770 which are near instant),
i suggest you try another project's GPU app, and report back,

I would, but it doesn't seem any other app is willing to let me run it on a card with only 256 MB of ram available to it. I know about that checkpoint thing, but it takes far longer than it should to get there. When it's working right, it does take about 11 seconds, like you said, to get to the checkpoint. Also, this is only after it gets started up by me being away from my computer, and then coming back. Using the menu to suspend apps, or selecting "Suspend" on the specific task, works correctly.

EDIT: Also, it's important for me to mention that it sometimes works, even when coming back from idle, but often doesn't.

What you could do is switch to Anonymous platform at Collatz,
then you could use the command parameters to reduce the load on the GPU,
(i used them to increase the load, but it made my display too laggy, so reduced them a bit)
the default parameters are <cmdline>L5 I8 S1</cmdline>,
while for GPU's with poor responce the recommended is: <cmdline>L3 I5 S1</cmdline>
i'm running <cmdline>L10 I7 S1</cmdline>

Edit: the other good thing about using Anonymous platform is it overides the GPU memory restriction,
so you can get work, then as long as your GPU still has enough Ram available to run the app, it'll work.
