Can't Obtain GPU WU

[rpalri]

I'm using a 2008 vintage PC with a NVIDIA GeForce 9400 GT.
It kept trying to obtain a WU assignment to no avail. Thinking it might be a problem with the server, I uninstalled F@H and reinstalled. Same deal each time. Lately the logs have shown that there was a problem connecting:

Code: Select all

The CPU slot is working but it seems a waste to just use it when the GPU has done so well in the past.

All device drivers are up to date and the F@H client version is 7.6.9. Is there something I'm missing?

[Joe_H]

The 9400 GT is too old to be used for GPU folding. Current minimum nVidia GPU would be one from the GT 400 series or newer, GT 600 or newer is recommended.

[rpalri]

Thanks for the information @Joe_H
My CPU remains underutilized too because 1 thread is kept for the GPU. Is there a way I can atleast put the CPU to 100% use?

[HaloJones]

delete the gpu slot, set the slider to full

[Neil-B]

... or edit the CPU slot and replace the CPU figure in there (possibly -1) with the full number of cores/threads you have.

[rpalri]

Nope. Neither of these worked. @HolaJones @Neil-B

[Neil-B]

Odd … can you post your log including the first couple of hundred lines and any latest config report … with no GPU slot and either -1 in CPU slot configuration with slider on Full or actual number of cores/threads in the CPU slot configuration should do it

[Neil-B]

Ah … hang on .. it won't change until the next WU … can't uplift CPUs above what was set at WU download.

[rpalri]

Oh. Okay. Let me wait and see. I'll update here as it finishes. ETA 23 hours 31 minutes.

[Crunchtimer]

Hi, I believe you can restart the Fahclient to get the GPU change in effect without losing the WU.
At least I can on both Windows and Linux.

You can also directly edit the config-file for the change as specified in this guide https://medium.com/@julsimon/running-fo ... 6bb8f84218 In Windows it's under C:\Users\User\AppData\Roaming\FAHClient/

However, today my GPU is not getting any work at all, so I think there is some problem with the GPU WU assignment generally today.

[Neil-B]

Iirc a WU can/will not run at a higher CPU core count that that it was downloaded at ... but I am happy to be proven wrong.

[rpalri]

@Crunchtimer Tried both y0our methods. Neither worked.

[JimboPalmer]

Honest, once you show us the first 200 lines of the log, the solution will go much faster.

It looks good to me.

`02:44:53:WARNING:WU01:FS01:AS lowered CPUs from 2 to 1` means that the current WU was downloaded when the CPU slot was allocated to use 1 CPUs. The system is attempting to bump that up that to 2 now but there is a restriction that prevents downloaded WUs from using more CPUs that when then client got it.

Your next CPU WU should be running with 2 CPUs as the config and logs look good otherwise.
