WU fails repeatedly - FAHclient needs to be reinstalled

[bruce]

You'll have to tell me how I can reproduce the problem on my system.

I don't know how you can reproduce the problem on your system.

I made almost 80Mio Points with my 1070 w/o any major issues but this behaviour is completely new

I checked GPU.txt. Some GPUs have several entries. What is the reason for that?
Is the Aorus 1080 TI Extreme Edition properly supported?

I checked GPU.txt. Some GPUs have several entries. What is the reason for that?

A GPU manufacturer assigns binary codes to unique hardware, not just a model number. e.g- they may distinguish between various VRAM configurations -- which FAH doesn't care about -- but we have to have a GPUs.txt entry for them all. Model numbers are a rather poor method of knowing which devices are "the same" from FAH's perspective.

Run GPU-Z Ior other GPU detection software) and it will tell you the binary codes for your GPU which have to match the left two columns of GPUs.txt,

Another issue is reuse of model numbers for cards using different GPU chips and released many months apart. For example, the nVidia GT 630 has been released several times based on two different Fermi chips and two different Kepler architecture chips. Same happened with the GT 640.

The reverse is also true. Often a GPU is "re-branded" with a model number of the next generation with no significant changes.

Thanks for the explaination. GPU ID fits to GPU.txt

Looks the same like viewtopic.php?f=96&t=30114&start=30
Folding works then after PC restart folding fails with Error initializing context: clCreateContext (999)

Maybe it is not the OpenCL.dll interface from Windows\SysWow64 (that is 32bit version) but the nvopencl.dll runtime version which makes a problem.
Can you check if that file changes version after a Windows reboot?
Should be nvopencl.dll CUDA 9.0.125 OpenCL 1.2 with latest driver. (CUDA runtime already 9.0 but FAH uses the OpenCL)

[foldinghomealone2]

Sorry for the late reply but I haven't rebooted my system for quite a while. Never touch a running system...

Long story short, no, nvopencl.dll doesn't change after a reboot

-

After a reboot I need to uninstall and reinstall FAHclient
During a uninstallation, only files in FAH-folder are deleted and files in start menue and screensaver. At least according to log after uninstallation is finished.
Therefore I assume that only those same files are installed after a reinstallation.

Can it be that files from FAHclient-folder crash during a reboot?

[bruce]

Can you guarantee that the OS's definition of PATH does not change with a reboot? That can alter which *.dll's are invoked when there's more than one version on your system.

Where did you install the client (and its data folder) ?

Nowhere in your logs I can find this kind of information: 20:25:21:WU00:FS00:Running FahCore: D:\FAHClient/FAHCoreWrapper.exe D:\FAHClientData\cores/fahwebx.stanford.edu/cores/Win32/AMD64/NVIDIA/Fermi/Core_21.fah/FahCore_21.exe -dir 00 -suffix 01 -version 704 -lifeline 2648 -checkpoint 15 -gpu-vendor nvidia -opencl-platform 0 -opencl-device 0 -cuda-device 0 -gpu 0 ...

[foldinghomealone2]

Meanwhile I have installed it on various locations with different client versions and express and manually and all the same.
And for sure I can't guarantee for what I don't know the OS is doing.

Ok, I don't know what to do about and it seems nobody else. No Problem.
Luckily reinstalling of FAH takes only about two minutes, so everytime I reboot, I reinstall the client.
No proper solution but at least a work-around that works so far.
Thanks for your help

What happens if you manually quit the client (from tray icon), wait for fahcores to exit, then restart Windows?

As I recall, when Windows does a restart after software update, processes may be killed suddenly.

[foldinghomealone2]

After every restart I have to reinstall

[toTOW]

Do you have some security solution or policy that could restore some parts of the system (and files) to a defined state at every reboot ?

[foldinghomealone2]

I thought about sth like that but now I'm already used to reinstall the client after every reboot. It takes less than 2 minutes.
As I'm folding 24/7 right now I don't restart often.

Don't worry, I can live with it right now.
Thank you all for your help.
