Hardware
- Bitscope blades provide power to pis via GPIO pins.
- Pis communicate via ethernet through switches.
- One pi acting as the designated head node.
- Access the head node pi through the router from the internet, and access the other pis via ssh from the head pi

Software
We first installed Ansible and wrote Ansible scripts to set up users and distribute ssh keys throughout the pi network to enable passwordless communication. We installed Slurm as our job scheduler, GCC for compiling, Openmpi for multinode interfacing when running tasks, spack for package management, and nfs-utils for sharing files across nodes.
