Hi,

Been using my GT520 for over 6 months to crunch MW GPU wu however over the last few weeks the GPU is no longer doing wu's. Has there been a change in the code or could I have a problem somewhere? The gt520 works fine in games etc.

Your computers page shows over 400 in progress for nvidia openCL for that computer. I would abort all WUs and try a detatch/reattach.

BOINC does not find the OpenCL driver for your GPU and Milkyway does not even see your GPU. "GPU detection will no longer work when BOINC is installed as a service, or protected application execution". BOINC isn't installed as a service, right? Could be a bug in the BOINC version (saw some reports about problems with 7.0.28 x64), a problem with the driver installation or something completely different.
I would try deinstall/clean/reinstall the gpu driver, than a newer BOINC version and see from there.

Have you tried a simple reboot? Windows can NOT reset the gpu without a reboot, so if Boinc 'lost' it it can't come back except thru a reboot. Also have you upgraded the Nvidia software lately? Not ALL upgrades are good for crunching, remember Nvidia is about the GAMING experience, not crunching, it is a 'oh it can do that too, cool' kind of thing. So sometimes new software updates can make gaming better but crunching not work at all.

I check my account on Milyway and surprised to see so many workunits there for the PC however in BOINC magaer there are no work units at all?

I have detached from Milkyway and then rebooted. Reattached Milkyway and the issue is still there.

I was running the latest Nvidia drivers 306.97, so I downgraded to 301.42 and rebooted and now I have all working.

Running GPU-Z show no ticks for opencl and PhysX for 306.97 but after downgrade to 301.42 it shows a tick in opencl and PhysX

So it looks like the 306.97 driver upgrade a few weeks back loses some functionality in at least the GT520

Thanks

Those are called 'ghost units', they are units the Server THINKS it sent but probably didn't really. They WILL go away as they expire and are sent to other user to crunch. Just ignore them as there is NOTHING you can do about them.

Last night I noticed my PC auto-updated the nvidia graphics drivers via Microsoft update back to Nvidia drivers 306.97 and everything is still working.

Running GPU-Z shows ticks for opencl and PhysX for 306.97 now whereas before it did not.

Anyway as long as it works that is great.

I just upgraded a machine to a PCI-E nVidia GT 520 (GT520) with 2GB, and experienced this problem. I had installed the absolute latest nVidia driver (310.90), and figured I had found the source of the problem. So I uninstalled the graphics driver and installed 306.97. I still get the same error messages:

GPU-Z shows ticks for opencl and PhysX (but it did for the newest version of the driver, as well).

Lets try updating your BOINC version as that can also cause the problem.

Yes, BOINC 6.x doesn't detect OpenCL capabilities, you need BOINC 7.x to run OpenCL apps.

That is not correct. I have hosts (both ATI and nVidia) running 6x (6.12.34, specifically) and they run the OpenCL GPU apps fine.

He is running 7.0.28 on that system.

Note that SETI@home applications that use the CUDA capabilities of this new nVidia GT 520 are being downloaded and run to completion, which is why I posted to this particular forum.

But back to the issue at hand, I was not running 6.x.x, but 7.0.28: supposedly the latest version available, according to the BOINC web site. However, I did download and install this 7.0.45 version, as suggested. I will let running tasks finish so that BOINC will cycle to download another set of work for Milkyway@Home. Then I can tell if that has gotten things straightened out.

Thanks for the suggestion. Stay tuned to this same Bat Channel.

That solved the problem (at least for now). I will reinstall the latest version - 310.90 - of the nVidia graphics driver for the GT 520 to learn if it was part of the problem or not.

Agreed (now 7.0.45 I noted), and doesn't change the fact the comment about 6x is faulty. ;-)

I observed no problems using the updated nVidia driver (310.90):

CUDA: NVIDIA GPU 0: GeForce GT 520 (driver version 310.90, CUDA version 5.0, compute capability 2.1, 2048MB, 1983MB available, 156 GFLOPS peak)
OpenCL: NVIDIA GPU 0: GeForce GT 520 (driver version 310.90, device version OpenCL 1.1 CUDA, 2048MB, 1983MB available, 156 GFLOPS peak)

with Milkyway OpenCL workunit downloading or execution.

Problem solved. Thanks for the assistance!

When using the newest version be sure to check out the 'change log' website here:
http://boinc.berkeley.edu/dev/forum_thread.php?id=6698&sort=5

just in case you have problems and they are known ones. Each change to a program can bring its own set of new problems.

I am glad you got your s working though!! You ARE now on the pointy end of the spear as far as Boinc versions go!!
