Raspberry Pi cluster for [email protected]

First off, I know these things won't set any records for number crunching, that is not the point.

So, why a cluster? For my soon to be 7 year old son. We just watched Contact tonight. So, he is pretty excited about SETI. Now, I could just spin up a PC and get it going for him, but I thought a RPi project would be more fun. I have an extra 5 port switch laying around, so thought a cluster would be fun. Plan to have him involved in the build.

So, the question becomes, how does BOINC and [email protected] handle clusters on Pi? I tried setting up a cluster years ago, but would need to find documentation on it again. If clusters are not supported, I guess I can set up the same sort of thing but run them independently. What would be the recommended version of the RPi be for running this?

Thoughts and suggestions would be great. As I said, a cluster is not s must. If nothing else I will get a few boards and run them as independent units. But, I would like to do a cluster again if possible.

I run mine individually. They are just stacked together physically.

Usually you would do a cluster for redundancy, my advice would be to run them independently but use one of them to control the others with boinctasks or the like. Is boinctasks still around? I haven't been keeping up.

I have 8 Pi's running [email protected], well 4 of them are actually Libre Computer Le Potato's. Universe runs a lot better than Seti on the Pi's. You would need at least a Raspberry Pi 3 B. Anything lower is probably too weak.

I just bought 3 more Pi's this past weekend, but I'm not running boinc on any of them. One is for my 3d printer, one for tinkering with CircuitPython and another I'm going to use as a backup desktop for when I do water cooling flushes on my desktop.

I was thinking 3 B+ or the cheaper version of the current 4. Pretty sure that has 1GB of ram. Figure that should be enough RAM for this. Unless I missed something.

I've often thought about building a cluster ever since I heard about the Beowulf project..basically turn old desktops into a supercomputer... but with a project like BOINC its redundant. It's already broken up into work units, it would be extra work. Like the guys said running individually and using Emfer's Boinctasks or use Boincstats page to control them. Just my 2 cents.
