As of this morning (US Central time), looks like the well has run dry again.

I'd like to figure out a work share setup that would allow WCG tasks to run to completion when the Rosetta tasks come back. I've never liked the "suspend one to do another" approach - I'd rather have what's in the queue finish up regardless of which project it belongs to.

That probably won't be easy with the massively different task deadlines, one way to try is to change the resource share settings, ie set WCG at 70 and Rosetta at 7 so WCG has a 10 times larger daily credit advantage. You will have to play with the numbers to see if you can get it to work for you though.

thanks i think i'd get a 8gb one when it becomes available at my local retailer. 1.5GB tends to be seen for the 'larger' wu, but i've at other times seen about 30% of memory used on a 4GB Pi4 with all 3 threads running. Perhaps it is because the wu just started running and like you've mentioned, they tend to increase in size over time. 8 GB would also means one can do away with all that zram stuff, there really isn't a point 'wasting' cpu cycles compressing and uncompressing memory. takes more power returns less points. swap and zram only make sense if it is used to keep 'unused' stuff.

do share the peak memory consumption that you observe, you can try running rpi-monitor which would capture that.
i'm thinking of getting a piece or two but my local distributor don't have stock yet
it seemed with 4GB and running 3 threads, i don't seem to see 'waiting for memory' situations frequently any more, but of course with 8GB it is more comfortable running all 4 threads
i noted credits earned seem lower with the more recent wu, various from robetta as they are prefixed with rb i'm not sure why

Has anyone tried the new Raspberry Pi OS (64 bit) yet?

I upgraded my Pi's a couple of days ago and they got about 30 updates and the kernel version went up. They appear to be running the same as before. I haven't specifically tried doing a "full-upgrade" as they suggest or a clean install of the 64 bit version, which they are saying is a beta version.

I'm currently doing the following to save power on my pi:
Disable HDMI:
sudo tvservice --off
Disable Wifi
echo "dtoverlay=disable-wifi" | sudo tee -a /boot/config.txt
Disable Bluetooth and bluetooth services
sudo systemctl disable hciuart
echo "dtoverlay=disable-bt" | sudo tee -a /boot/config.txt
Turn off Power LED:
echo 0 | sudo tee /sys/class/leds/led1/brightness
Have you done any power testing with Ethernet vs Wifi?

I usually blacklist the WiFi and Bluetooth. Not to save power. I have 20 Pi's and I would rather they not use WiFi at all, there wouldn't be much bandwidth left for the other devices. Most of them are Pi3's so are running Einstein work.

cd /etc/modprobe.d
sudo nano raspi-blacklist.conf and add the following
# wifi
blacklist brcmfmac
blacklist brcmutil
# bluetooth
blacklist btbcm

Not sure if they are still correct, I got this from forum posts on raspberrypi.org some years ago. I also remove the pi-bluetooth package.

hi, Pi4 has got a new 8GB version, and more importantly 64 bit OS ;)

it seem to be something to try out, it is Beta though,
this is really on the bleeding edge lol

If you have rosetta@home installed on your Raspberry Pi4 (running Raspbian 'buster') but you don't get any work to be processed then check here:
https://www.element14.com/community/people/gam3t3ch/blog/2020/04/09/rosettahome-on-raspbian-pi-4

Adding just a few lines to one of the configuration-files will solve these problems.

I have been running rosetta@home for a couple of weeks now and my Pi4 has never been idle... Enough work to do!

Good luck,
Adam

What you have measured just highlights what I have mentioned above: you can't trick physics. If you are bumping up the the voltage and disabling a core, you are losing efficiency.

Comparing top scores doesn't make sense.

I've recommended to compare a RAC over many weeks (>2), preferably from the same time interval. ~1000 RAC does sound realistic for a Raspberry Pi 4. dcdc's system doesn't seem to be crunching since long and it's not in continuous operation:

If it is not cooled properly, it will throttle itself even above 60C, but otherwise the values should match closely between well-cooled devices.

You also didn't seem to have picked up my hint that if you use a titanium ATX PSU to power multiple Pi's then it will vastly increase the performance/watt ratio (compared to ~60-70% wall warts) and that if you purchase 100 Pi devices they will give you a huge discount - I've tried this myself.
