I believe that the Einstein project was one of those that I had looked at previously as well. I would like to direct you to an earlier post where one of the Balena team answered a question I had regarding unsupported projects listed in the Folding client here:
… in particular @jtonello mentioned that Berkeley had made a custom image for Balena to use with Rosetta. It still seems to be the case (ie a quick Google on a mobile phone) that the Pi does not have much love or support in the realms of distributed computing because they cannot complete (large) work units fast enough. I would like to see Balena making more projects easily accessible but it clearly requires close co-operation with third parties to make it work, and given the largely volunteer driven eco-system I do not want to make Balena out to be lacking in any way here.
Personally I think small but high up-time SBC’s and the like are a wasted resource since they are cheap and out there in large numbers often owned by enthusiasts and tech savvy hobbyists. My other regular hardware platform is an i7 based laptop that would clearly be “better” than a Pi for knocking out work units and more widely supported than ARM. However it’s only on for a couple of hours a week and therefore would not complete any work units within their allotted time. But I do have Pi’s on 24/7, including one that was dedicated solely to the task thanks to the Balena image. It might have been comparitively slow but it was reliable and consistent.
Thinking about my home at the moment at any given time I have at least 3 Pi’s permanently connected and doing things with only one of them under any real load. The other two barely register any load at all over a 24hr period and would be ideal candidates for running distributed computing on in their spare time since they have lots of that. I will look into running distributed projects on the Pi again when I have the time and if I find anything that looks particularly interesting I will post it back here.
