I wonder if there is something to be said for not using Ethernet in something like this? Perhaps it is possible to make a kind of IP over GPIO interface, or attach them all directly to a USB bus?
It just seems to me like RasPi -> USB -> Ethernet (for less than 1m) -> USB -> RasPi has a layer or two more than necessary (and I believe the on-board ethernets on RasPi are USB interfaces to the chip too).
Could be an interesting project...
- Accujack 6y agoIt would be educational. I'd say the most interesting way to approach this at the moment would be to use RasPi 4s and link them via the PCI express bus. None of this stuff is more than educational, though. I admire this build because it's almost a rite of passage for nerds to build a cluster, but when you're all done and the cool wears off you've basically got a pile of obsolete hardware for which you need to find a home.
