Project: 9704 (Run 35, Clone 16, Gen 99) - Bad WU?

[weirddan455]

I've been having problems folding Core 21 WUs and started a topic here:

viewtopic.php?f=74&t=28207

But this time the WU actually ended early, not just stalled (it did stall at ~74% but I restarted it, it got to 87%, and then ended early.) This is the first time I've had a WU end early like this so I'm wondering is this a bad WU or a problem on my end? Also did I get any points for this or no?

This is the first time I've had a WU end early like this so I'm wondering is this a bad WU or a problem on my end? Also did I get any points for this or no?

Can't tell easily. It will be reassigned, if someone else completes it then it's (nominally) your problem, though if it's a one-off there's not much you can do. If it fails for others too it's a bad WU. A mod should be able to find out whether anyone else completes it. You should get partial credit, but it's not guaranteed.

You received partial credit for returning an incomplete WU. It was reassigned and completed successfully by the next person. It's not a bad WU.

Hi weirddan455 (team 45032),
Your WU (P9704 R35 C16 G99) was added to the stats database on 2015-10-23 08:07:59 for 7830 points of credit.

Hi ***** (team ****),
Your WU (P9704 R35 C16 G99) was added to the stats database on 2015-10-24 11:08:22 for 16668 points of credit.

Hmm... so what does that error mean then?

I gotta figure out what's going on with these Core 21 WUs and see if there's anything I can do on my end to fix things.

[Grandpa_01]

It could be caused by any one of a number of things. Is the card overclocked, if so you may want to tone it down a little. I see it is a GTX 770 if it is not OCed and you are comfortable with adding voltage to it try giving it a little voltage bump and see if that helps. Those are just some basic trouble shooting steps you can give a try.

[weirddan455]

I have this card:

http://www.gigabyte.com/products/produc ... id=4629#ov

It's factory overclocked by ~100mhz. I haven't done any overclocking myself or messed with the voltages though and it's stable in everything else I've done including folding Core 17 and 18 WUs. I think I'll just wait and see what happens when I get my next Core 21 WU.

This kind of errors (clEnqueueNDRangeKernel (-4)) are OpenCL errors (-4 error code is CL_MEM_OBJECT_ALLOCATION_FAILURE). If you were running Windows, I would say it was a driver reset (most likely TDR issue), but I don't know if Linux has a similar mechanism.

OpenCL errors are usually driver or OS related errors : inability to allocate ressources, either because the device is not reachable (during a driver reset because of TDR on Windows) or because something else is also trying to allocate ressources at the same time.
