2 years ago at one Meetup in Paris, Marc Girondot, professor at University Paris-Saclay, presented his cluster built with 12 Odroid (equivalent to Rapsberry Pi). The stack was almost the same size than your picture as there was no fan and a narrower distance between each PCB card. There were many more cables. For a total cost of less than 1000 € and an electrical consumption reduced by a factor of 7, he got the same calculation capabilities than the most expensive Intel i7 processor. He used an Arch Linux distribution and Spark to distribute the load to every processor and then centralize the results to one processor equipped with a keyboard, a mouse, a screen and a hard disk.

Yes, you could argue that it's merely a toy.... but it's bigger and cheaper than the AWS box that currently hosts my web site, RStudio server, and Shiny server! > Got it. Missed the cluster part earlier and then confused myself looking for arm64 16core machines. There aren't any :) >> For the truly curious, you can view my RPi cluster here: https://photos.app.goo.gl/kALwoYCVxJ32VgxEA > Neat :) Very geek chic!
