Recently I acquired a Raspberry Pi 4 and decided to build a tiny computer cluster out of it. The goal is to do play around a bit with parallel computing technology. Some of the things that I will try out are
MPI in Fortran
Coarray Fortran
Parallel computing with julia
The cluster consists of the following parts (see image above).
1 Raspberry 4 Model B (2GB) equipped with a 16GB MicroSD Card
1 Cluster HAT v2.5
4 Raspberry Pi Zeros W (each with a 16GB MicroSD Card)
A pretty case and some cables

The software for the cluster is available here. I chose the full cbridge variant which is Debian based. Additionally I enabled SSH and rdp, so that I can attach the cluster to my network and access it from my main machines at home.
