RE: My WU logs We can't


We can't read the outcomes like that. We can read them like this.

GPU RAM cant be a problem - almost all(1 Gb) free.


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:

Quote:
20/08/2012 14:36:25 | | ATI GPU 0: Juniper (CAL version 1.4.1664, 1024MB, 1005MB available, 2016 GFLOPS peak)
20/08/2012 14:36:25 | | OpenCL: ATI GPU 0: Juniper (driver version CAL 1.4.1664, device version OpenCL 1.1 AMD-APP-SDK-v2.4 (595.10), 1024MB, 1005MB available)

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:
http://einsteinathome.org/host/2896418/tasks
[15:51:43][3012][ERROR] Error during OpenCL kernel setup: HSFFB (error: -5)
[15:51:43][3012][ERROR] Demodulation failed (error: 2019)!
(0x7e3) - exit code 2019 (0x7e3)
or
[16:51:34][6032][ERROR] Error during OpenCL kernel setup: TSMP_T (error: -5)
[16:51:34][6032][ERROR] Demodulation failed (error: 2019)!
(0x7e3) - exit code 2019 (0x7e3)

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: I'm running BOINC ver

Quote:

I'm running BOINC ver 7.0.28 (x64) on a Windows 7 desktop. Yesterday I updated AMD Catalyst Control Center to the latest version 2012.0928 in order to use the GPU on the Radeon HD 5450 videocard. The CPU is now crunching 4 tasks. There is running a 5th task that started more than 24 hrs ago, and the status is: progress 13% (!), running 0,5 CPUs + 1 ATIGPU, time past 2:08 and time to go 4:52.
There must be something that causes this very slow GPU-action, but I cannot find the cause. Does somebody have suggestions? Thanks in advance.

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.

this line in the start-up

this line in the start-up logging of your BOINC manager event log concerns me:

Quote:
Sun 29 Sep 2013 07:29:24 PM CEST | | Running as a daemon

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).
