Hiyo!

I'm having a problem lately with a large amount of GPUGRID processes ending with computational errors, the exit status is always 'Exit status -9 (0xfffffffffffffff7) Unknown error number'

I am running a GTX 650Ti, along with a GTS 450. Both cards are readable and usable by BOINC. I have other projects (namely Milkyway@Home lately) happily using both cards and not ending with any compute errors.

Both cards are running at temperetures normal to them, and both are not overclocked, and the power supply is more than adequate for the cards.


I would greatly appreciate any help you can give!

For one thing disallow the beta apps in your project preferences. 7 of the 8 that errored were betas.

These workunits are beta test tasks (intended mainly for GTX 780 and TITAN). They should work on every card however, but apparently they are not perfect yet. You should set up your profile to avoid those workunits by the following steps:
1. Go to your profile
2. Look for the "Preferences" section and click on "GPUGrid preferences"
3. Click on "Edit GPUGrid preferences"
4. Uncheck the "Run test applications"
5. Uncheck the "ACEMD beta" among the "Run only the selected applications"
6. Uncheck the "If no work for selected applications is available, accept work from other applications?"
7. Save the changes
8. Repeat steps 3-7 for every different preference sets you might have (Default, Home, School, Work, etc)
9. Initiate a project refresh in your BOINC client

I am running a GTX 650Ti, along with a GTS 450. Both cards are readable and usable by BOINC. I have other projects (namely Milkyway@Home lately) happily using both cards and not ending with any compute errors.

These cards are not performing so great at Milkyway@Home, since that project uses Double Precision arithmetic on the GPU, and (besides the GTX 780 and the TITAN) the consumer (GeForce) NVidia cards have reduced DP capability. Therefore the Milkyway@home (and many other) project is not adequate test to prove if your hardware is capable handling GPUGrid, because this project uses the full capability of your cards. You can put them in better use here at GPUGrid.

Ah. I was under the impression that GTX650Ti and GTS450 were pretty unimpressive and not all that great for something as demanding as GPUGRID.

The GTX650Ti is capable of handling even the long workunits within 24h, but the GTS450 should be used only for short tasks. But you can't do that if they're in the same PC.
