Genefer WR returns in error
Author |

Hey !
One of my rig's keeps returning GFN WR's with error.
I'm running the Genefer's with 2x EVGA GTX780Ti KPE (Kingpin Edition)
This GPU comes with a factory OC.
Could someone tell by the error code what seems to be the problem?

I think you need proper OpenCL driver (not sure where to point you) or change to CUDA tasks. Or perhaps you have AMD OpenCL box checked and not Nvidia one.

You can always get the drivers at http://www.Nvidia.com | |

Thanks for feedback guy's but....
This has been a problem over some time, and many drivers has been updated since my first GFN WR.
I have also always chose OpenCL in the preferences.
If OpenCL is not included in each Nvidia driver package, I'll have to check this out.
Was hoping for someone could read from the error codes the tasks returned what they meant.
Error code 2964 and 2999
The other day I tried to lower the factory OC to 85%. I thought this was a hit but after 23hrs it failed.
I have to confess, this is two cards set up in SLI, it may disturb the Genefers.
I have yet to try to disable this.
Edit:
OpenCL is included in each Nvidia driver package, yet the WU reports:
Starting initialization...
Initialization complete (123.196 seconds).
Testing 41828^4194304+1...
Error: OpenCL error detected: CL_INVALID_COMMAND_QUEUE.
An error (2964) occured.

Unfortunately I'm busy with RL stuff and that will not change in the near future, so I'm not available to offer a lot of help. Some thoughts on the matter:
1) The OpenCL driver is included in the Nvidia drivers, so that shouldn't be the problem. In addition, from the stderr txt, it's clear that the app sees the GPU as an OpenCL device.
2) I'm not as familiar with OpenCL as I am with CUDA, but there are environmental conditions (e.g., using Windows Remote Desktop) that could cause the GPU to be unavailable. Perhaps something similar is happening here.
3) Do any other OpenCL programs work on your GPU? wwwwcl.exe (userd for WSS and Wieferich on PRPNet) is also an OpenCL app.
I can't guarantee when, or if, I'll be available for followup answers.

Thanks for the reply Michael
I run GFN WR's on several rig's. The GPU's represented is:
GTX660Ti
GTX690
GTX760
GTX780Ti
GTX980
All run just fine. It's just the pair of GTX780Ti KPE edition that causes this problem.
The KPE edition has some differences compared to other 780Ti's, but OpenCL from other projects run fine on this card.
I have more or less settled with this card in particular does not run GFN WR's, and I'm ok with it, so don't use any efforts on this one case.
I was more like curious on why.
Thanks

(This thread was moved into the GFN topic.)
