Building Raspberry PI Supercomputers

on YouTube ↗22m

" summary

Live tutorial runs one or two Raspberry Pi clusters and focuses on management not hardware, showing a working PicoCluster rack, image choices (Raspbian vs Ubuntu/Fedora), and a reproducible setup: consistent UIDs, passwordless SSH keys (genkeys and ssh-import-id), NFS shared /home for MPI binaries, systemd time sync, and wired+Wi‑Fi routing order to avoid routing errors. Demonstrations use parallel-ssh to run pings, temperature sensors, and stress CPU while driving Pimoroni Blink LEDs to visualize load; MPI examples and Mathematica analysis are available in the recorded followup.
