RE: My WU logs We can't
)
We can't read the outcomes like that. We can read them like this.
Try a reboot anyway. That's the only way to completely clear GPU memory. And if the tasks run fine after the reboot, then it was a lack of GPU memory.
Of course I tried to reboot
)
Of course I tried to reboot several times(and reinstall few versions of AMD drivers with reboot of course). And check the BOINC log that displays there was a lot of free GPU RAM immediately before the application starts, for example:
But in any case this is not actual any more. After update E@H OpenCL application to version 1.28 error with the lack of free memory at once disappeared (which confirms that the problem was not in amount of free RAM, but a bug - in the application or in the AMD drivers or probably both).
But 1.28 app still not working - just another error in all Wus:

[15:51:43][3012][ERROR] Error during OpenCL kernel setup: HSFFB (error: -5)
[15:51:43][3012][ERROR] Demodulation failed (error: 2019)!

or

And POEM@Home OpenCL app still work fine on same hard&soft: http://boinc.fzk.de/poem/results.php?hostid=109617
My Mac ATI GPU won't stop
)
My Mac ATI GPU won't stop even though "Use GPU while computer is in use" is unchecked; all the CPU processes respond to "While computer is in use" and stop as expected when I want to work. This greatly interferes with screen drawing operations. Can this be fixed? Is there a work-around in the meantime?
Thanks.
BTW: The Tasks pane SAYS the GPU is suspended, but it keeps ticking away!
Did you try to right-click

Did you try to right-click the BOINC-symbol?
It has an option to pause gpu-work.

RE: There must be something

The OpenCL GPU application here at Einstein likes it best when it can utilize a full CPU core. In order to do that, you set up BOINC to use all cores minus one, e.g. on your 4 core CPU, set your preferences (*) to "On multiprocessors, use at most 75% of the processors". That way, yes, only 3 tasks will run on the CPU cores, but at least that last CPU core will now be fully utilized by the GPU application. And that speeds up the work.
(*) Or the local advanced preferences if you happen to use those. You can recognize that when your start-up messages tell you "Reading preferences override file".

Hi Ageless,
I changed the setting as you advised and it seems to work well.
Thanks for your very quick response.

Thanx in advance for your help!
this line in the start-up

this line in the start-up logging of your BOINC manager event log concerns me:
it suggests that you installed BOINC as a service and not as a standard application. i presume you checked the "Protected application execution" box during BOINC installation? installing BOINC like that prevents it from using GPUs. uninstall BOINC and, upon re-installation, uncheck the "Protected application execution" box. then BOINC should detect the GPU, assuming it is the most powerful GPU in the system.
if it doesn't detect the GPU by now, it may be b/c it isn't the most powerful GPU in the system. you may also need to add a cc_config.xml file containing the line "1" to the BOINC data directory, which obviously allows BOINC to recognize the less powerful GPUs in a system as well. so if you have other GPUs in the system that you would like BOINC to ignore, you'll also have to include one of the "ignore GPU" statement in your cc_config.xml file as well (N, N, or N).
if BOINC hasn't detected the GPU by now, it may be due to the older version of BOINC that you're running. according to the BOINC download page, v7.0.65 is the latest release version of BOINC for Linux Ubuntu (it may not work with other Linux distros, and i have no idea what distro you are running, but it may be worth a try if the above solutions don't work for you).
