Folding on WIndows 11 ARM (Snapdragon X plus/elite)

[Ncard00]

Just tried folding@Home on my new Snapdragon x plus WIndows 11 ARM laptop, and even though I've enabled all 8 CPU cores, I'm only seeing 50% CPU utilization.

Does anybody have a solution to this?

Also, the tasks are x64, not native ARM64, when will native support be added?

Not soon.

You might try the arm Linux tarball in WSL.

There are no folding cores compiled for Windows ARM, so the suggestion of trying the Linux installation under WSL is the only way to have native cores running.

[calxalot]

I suggested the tarball because I assume the systemd install won’t work in WSL.

WSL supports systemd now

Now I'm not getting any work on my snapdragon x plus laptop, hope somebody can help me out

Update, now getting work, but only 50% CPU utilization, why? ALl cores are enabled in settings.

Did you switch to the Linux arm build?

I could, but I want this to be plug and play easy to use, otherwise It's not worth it.

Important update!

I can see that on my x plus Snapdragon laptop, even with all my 8 cores enabled for FAH, the default WIndows Task Manager is the lowest "low" priority, and setting it to normal doesn't fix this.

You have to set the priority to "Above Normal" and you'll get 100% utilization that way.

Since FAH doesn't have the advanced option anymore with the "minimal, normal, full" slider or whatever, please fix this issue, so the default priority for FAH on WIndows 11 ARM is "above normal", and if users want lower utilization, they just lower the amount of cores they wanna use.

I really really really don't think this is a fahclient issue. FAH does not develop windows scheduler.
Giving fahcores above normal priority is bad idea, as computer will become unresponsive. Whatever is messed up on ARM windows, is ARM windows issue, and not FAH issue

Fair, but my computer is not unresponsive at all, for doing basic daily tasks while FAH is running at 100% CPU utilization, and for 24/7 folding, you're not using it for the 8 hours you're sleeping anyway.

I've now finished testing FAH PPD with this fix.

Before I got 35.000 PPD, now I peaked at 111.720 PPD.

That's a performance increase of more than 300%!

Also, below are some performance increase estimates for other Snapdragon chips:

X1 Elite (84-100) up from 55.000 to 165.000 PPD

And then the upcoming X2 Elite Extreme, up from 90.000 to an insane 450.000+ PPD, for the highest TDP variant!

Your computer is doing fine because windows on arm scheduler is so messed up, that it sets priority wrong.
In normal windows if you set FAHCore to anything other than normal, things just start to go to hell
