Granular control of GPU slots

[ostieca]

Hi there,

First time here, been folding since March 2020. I'm trying to add my work laptop (Lenovo P43s) to my current "farm" but I can't find a way to be able to let it fold at any half-decent rate. The problem being that both onboard GPUs (UHD Graphic 620 and Quadro P620) are sharing the same ridicule cooling system. I just added a Razer Core X eGPU with a RX 470 but I'm struggling -at least as much as the built-in GPU detection mechanism of the current Folding@home software it seems- to make the whole system to behave like it should. I need a way so that only the RX 470 and the CPU are used, but I failed so far. Deleting the two unwanted GPU slots isn't helping: 1. because it's to be done all over again after a reboot 2. because even if I deleted the iGPU in the Advanced Control, it is still showed in the Web Control page 3. Even if Web Control and Advanced Control show that it's folding on the RX 470, it's in fact folding on the iGPU based on Task Manager and GPU-Z monitoring data. Not hearing the fans speeding up on the RX 470 was the sign something was wrong. Disabling the iGPU in the BIOS is not an option as I need it for the laptop's monitor. I don't think pausing at the startup the two GPU slots will help as I have to toggle between Start and Pause multiple times a day.

Any way it can be done without having to wait for an update version of the software?

In Advanced Control (aka FAHControl), which you will find in the ^ menu of the taskbar ("Show hidden icons", on the right side of the taskbar, then click the molecule icon), you can set an option called pause-on-start = true for the GPUs slots (Configure -> Slots -> double-clic the GPU slot -> Add -> Name: pause-on-start; Value: true). Then those slots won't fold unless you specifically demand it (right click on the slot in Advanced Control, choose "Fold"). It should do the trick.

It indeed did the trick of giving individual control, thank you!

Alas, I still can't use it as F@h falsely believe folding on the eGPU while in fact, it's the iGPU that is doing the work (very poorly). Hopefully, I'll figure out how to work around this.

Can you post your log inc top 100 lines or so showing what fsh thinks your kit is .. it might be something in the slot config

Your Intel is configured as Bus 0 slot 2, but I think it should be slot id 0

If you copy down your user, team, and pass key and uninstall including data, and then reinstall, I find that it is more likely to correctly configure hardware.
In the past it has been difficult to make GPUs from different vendors fold at the same time.

[ostieca]

I did a clean install and I'm getting the exact same result. Must be the way the laptop route data in the multi-GPU environment.

[JimboPalmer]

the laptop

I missed that this was a laptop. Many laptops swap Intel and discrete GPUs based on the amount of graphics needed and battery life. That will add even more confusion to your quest.

Graphics adapter NVIDIA Quadro P520 - 2048 MB, Core: 1303-1493 MHz, Memory: 1500 MHz, GDDR5, 64-bit interface, Nvidia 431.94, Optimus https://www.notebookcheck.net/Lenovo-Th ... 972.0.html
https://www.nvidia.com/en-us/geforce/te ... echnology/

This means the Nvidia (in this case) and Intel GPU are never both active at once, and that the Nvidia GPU may not be available when the Work Unit starts.

I honestly recommend you stick to CPU folding, as the method of configuring the switching is not consistent.

[ajm]

I would ask Lenovo if they can come with a solution or a workaround. It strongly looks like a bug in their system.

[Neil-B]

I regularly use (and have currently) both my Intel iGPU and the NVidia dGPU working fine (albeit on dell systems) both folding and quite happily running displays - cooling is an issue but actually dropping cpu slot and running both gpus has been manageable - the cpu folding was the worst heat culprit ... fairly sure it will be just a configuration issue might be bios (doubt) or NVidia Optimus/Intel Graphics settings (more likely) - I'll do a bit of research into Lenovo laptops ... there may be quite a challenge getting the eGPU to fold - not least because it is a mix and match between NVidia and AMD - I reckon it ought to be possible but it may be interesting.

What I am trying to say is "Don't give up" ... If you are up for it I'd go back to basics - firstly finish and pause the cpu slot to get it out of the way and stop it heating up to laptop - then get one of the two internal gpu slots running (the NVidia dGPU might be easiest) - once you have that working then worry about the Intel iGPU (flag may need to be set to get this working right iirc still beta) ... I'd leave the AMD eGPU to last ... but break it down into different bites - trying to resolve all at once may just be more trouble and take longer than doing one at a time.

The gpus will out perform the cpu - and with a laptop having heat problems drop the cpu first

[ostieca]

Victory!

Had to go to Windows 10 Graphics settings, enable Hardware Acceleration, and tell Windows to run the following process on the eGPU:

FAHClient.exe
FAHCoreWrapper.exe
FahCore_22.exe

Thanks everyone for the support!

[Neil-B]

Congratulations ... and Thanks for reporting back ... goood to know it is possible

[PantherX]

Welcome to the F@H Forum ostieca,

Glad that you found a solution and thanks for sharing! Just wanted to point out that while most GPU WUs are using FahCore_22, you might get some WUs from FahCore_21 so if you see any failures in your log regarding FahCore_21, you may want to update that list.
