Last Night I ordered the PicoCluster 5H kit from PicoCluster and 5 RPI 4 4GB SBC boards from PiShop.us. The weather hasn’t been ideal to fly my model aircraft so I am starting another distraction from the Pandemic. I’m building a RPI4 based “Supercomputer” ! This cluster will have a similar environment to what you would see running on the large clusters at NASA, NOAA, and the Department of Energy. It will use a lot less power than the IBM p720 I had running in my basement. The speed and high availability may surprise you. I will be using the little RPI4 cluster for HPC, and Kubernetes.
