" summary

Clear, actionable checklist: a three‑ to four‑node Raspberry Pi cluster built from a picoCluster case with a USB or USB‑C power distribution board and a Netgear switch, noisy fan replaced by a Noctua fan, LED status from a pymoroni LED array, boots from SD cards, uses static ethernet plus Wi‑Fi DHCP for mobility, SSH keys via genkey.sh or ssh‑import-id, parallel control with pssh, shared NFS for code, strict time sync, and MPI for numerical runs — watch for SD corruption and fstab mistakes.
