Raspberry Pi 4 Cluster

[jockster]

Hi

I am just about to buy 4 x Raspberry Pi 4's as a project to set up a cluster.

Could I run folding@home on the cluster and get the benefits of the cluster?

Would make a good first cluster project if I could,

Many thanks, Simon

Welcome to the F@H Forum jockster,

Please note that F@H doesn't support Raspberry Pi architecture

For a list of supported systems, please review the post 4 - Getting Started With F@H (Basic) here: viewtopic.php?f=24&t=26036

I would look at Rosetta@Home running 64 bit Ubuntu

"Rosetta at Home has a Pi client now. You'll need a 64-bit kernel, at least, to run the tasks. It's far easier to just put a 64-bit clean Ubuntu on it than to mess with it in Raspbian, though you could do that if you wanted.

If you've got a good heatsink/fan for it, you can probably overvolt by "4" and push clocks to 2GHz too, but that won't gain you much without a big heatsink as it runs a lot hotter.

You need a 64-bit kernel for the BOINC stuff, and I think you need at least some 64-bit userspace libraries as well. Raspbian is a 32-bit userspace and while it ships with a 64-bit kernel now, it's not used by default. It's harder to get all of that working than to just put a 64-bit OS/kernel on in the first place.

I wouldn't say I like it more or less, just that if you want the Pi to do nothing but run Rosetta tasks, Ubuntu is easier to get going." - https://arstechnica.com/civis/viewtopic.php?p=38854679

I would do raspbian over Ubuntu as it’s lighter weight and easier to do things like turn off HDMI. There is a long thread on the Rosetta forums about setting up a pi 4:

You might get to fold on them as a early client exists for ARM. No idea when it will sow up in beta form.

FAH has strictly limited itself to the x86 instruction set and extensions of it. In the past there have been excursions onto other platforms inducing the Apple's PowerPC, the X-Box's PowerPC and the Sony ARM client. Each of those excursions was terminated ... most likely because of the support costing more than the net benefit of adding a relatively small number of additional processors to FAH's research. Raspberry Pi would probably be in the same category.

I recommend you use your cluster for BOINC.
