Hello there after config my rpi 3b for fold for covid., shows:
Rosetta needs 3gb but only 900mb
How can I solve it?
Greetings and stay in home

only PI 4 s are supported at the moment and PI 4 s with 4G+ RAM are preferred (mine only has 2G)
Hi,
I have the same problem.
According to: https://foldforcovid.io/#faqs Also RPI3 should work now. There was even a blog post that now more devices are supported.
https://www.balena.io/blog/balena-enables-more-devices-to-join-rosetta-home-to-research-covid-19/
Any information on this?
my bad :sorry: i was told earlier on this forum that only 64 bit ARMs were supported !
but i forget that balena have a PI 3 64 bit OS ! has anyone got a PI 3 64 working yet ?
Hey folks - the Pi 3 will work, and indeed I have a few here that are crunching, but they will only do work when the Rosetta project assigns tasks that are able to run with the lower amount of memory. So definitely set Pi 3s up and keep them online, as it means as soon as those tasks are set up the device will start crunching 
We’ll get this information added to the FAQ on the site.
P.S. welcome to the community @londere!

Hi @chrisys ,
ok, thanks. Maybe the application output is also misleading:

… looks a bit like the “boot process” was stopped, as the system requirements are not met.
Can you confirm that this is “as intended”?
Thanks

yes and no
needs 1907.35 MB RAM but only 966.82 MB is available for use
looks like you need a PI 3 with > 4G
i will try and reproduce but my PI says it only has 1G ! so maybe theres no hope for me
however i am using a 32 bit OS so will reimage with a 64 bit to see if memory increases

RPI3 always has 1GB.
Only RPI4 has options from 1-4GB.

so how can rosetta ever work on a PI 3 then ?

oh dear i have even less RAM when i switch to PI OS 64bit

This project should run on 64-bit OS devices with 1 or more GB of RAM, but we’ve tested on the below:
Raspberry Pi 3 (1GB RAM)
Raspberry Pi 4 (1GB RAM)
Raspberry Pi 4 (2GB RAM)
Raspberry Pi 4 (4GB RAM)
and make sure you pull latest rosetta from github since start.sh has changed
totalmem=$(awk '/^MemTotal:/{print $2}' /proc/meminfo)
if [ "$totalmem" -lt "2500000" ]; then
echo "Less than 2.5GB RAM - running single concurrent task"
exec boinc --allow_remote_gui_rpc --fetch_minimal_work
else
exec boinc --allow_remote_gui_rpc
fi
result !
you MUST get latest code from github that supports < 2G ram and use PUBLIC URL via CLOUD gui instead of rosetta.local URLs which do not work
The Raspberry Pi 3 (running 64-bit OS) is available, but, there are not many work units available that fit within the 1gb RAM threshold. As the Baker Lab researchers load up work units into the Rosetta queue, most of them require 2gb of memory. There are a few however, that are smaller, and if any are available the Pi 3 will grab them.
So for now, if you have a 1gb RAM device and are not receiving any tasks you will simply need to wait for some smaller units to become available.
Hello dtischler,
I’m in the same situation and I was a little upset when I saw this memory lack on my RaspPI3, Therefore I decided to join forum to check if it was common issue. I admit i didn’t know there was a task queue. It would be helpful to learn a little bit about this queue and how tasks are assigned, how often and how it decides the device.
How ever I will let my RaspPi3 powered to check if it’s worth it the energy consuming and if at least once in a while Rosetta assigns a task to it.

mi PI 3 has been running 110% CPU for over 36 hours at 5V and ~0.6A so only used 200 Wh
1000 Wh in the UK cost 15p
Mine is running two tasks now, I rebooted the Pi twice as it seemed stuck (first time gave up due to the 1Gb memory issue), then there was some server issue but now it seems OK.

nice one ! whats your ranking in the TEAM list ? i got as high as 16th
How to find the TEAM ranking? My Pi3B+ seems to spend a lot of time waiting for tasks…
BOINC TEAM RANKINGS
https://boinc.bakerlab.org/rosetta/team_members.php?teamid=18832
if you are not ranked then get a KEY from
https://boinc.bakerlab.org/rosetta/weak_auth.php
then add it to YOU APP
wait 24 hrs then you should appear in the ranking
dont worry about waiting for jobs there are only a few jobs for CPUs with <2G RAM
it is a problem for all PI users (we will always be outranked by INUC users)
maybe @balenamktg could setup a separate team for PI users to give us a fair chance ?
