Re: Initial impressions for fast ARM hardware

I measure SoC power impact w/ FAH process active.
Power at wall (with screen sleep) is usually 2-5W higher

Re: Initial impressions for fast ARM hardware

Do you get the same result using ProcessType Background? I haven't tested it. I suppose it should be an equivalent in terms of CPU cores scheduling. Not sure if there additional restrictions applied by OS for "background" daemons Does FAHControl work properly with the background clamped c...

Re: Initial impressions for fast ARM hardware

At this power level I can keep it running 24/7 even on battery power How well does it do with completing wus within timeout? It haven't completed single WU yet. After running WU 16955 overnight it's at 30% and 1.26 days left (ETA) with 4.46 days left to complete. Upd on power and PPD: 3.5k @ 0.33W

Re: Initial impressions for fast ARM hardware

It's possible to run FAHClient exclusively on E-cores.

This involves some QoS magic and LaunchDaemons/org.foldingathome.fahclient.plist editing
macbook air m1
PPD est: ~24k (most likely overestimated)
Package power: 465 mW

Re: Initial impressions for fast ARM hardware

+ Macs Fan Control to force min 2500 rpm
Final WU score: 227k PPD @30W or 7566 PPD/W
Properly optimized native version will be around 10k PPD/W

Re: Initial impressions for fast ARM hardware

I've managed to max out m1 pro (10 core) CPU. Configure -> Slots -> 8 CPUs (= number of P-cores) Configure -> Advanced -> Priority slightly higher (to avoid E-cores) Output is 145k PPD at 20W SoC power Some observations: P-cores are running at 2.1 GHz, fans are nearly inaudible at 1500 rpm, looks li...
