Cluster

Published on: January 23, 2025

Intro

This story begins with bored browsing of AliExpress, as all good tales do. I discovered the wonderous Orange Pi Zero 3, which can be had for around about £10. I instantly ordered 9 of them. This is the madness that ensued

The Cluster Setup

I got to work building a small cluster, originally I planned on an 8 worked node cluster with 1 head node but it quickly dwindled down to 6 worker nodes after 2 of the OPIs went to be their own servers (ADSB tracking and OctiPrint respectively). I started by getting PSSH working and started trying to setup SLURM.

SLURM

My original plan was to use the cluster for messing around with SLURM, however that quickly fell through after I just couldnt get it work no matter what I tried, with MUNGE (the software allowing the communication between each node) just not working properly. So I put it on the back burner for now.

The Future of the Cluster

In future I want to get the cluster working on cracking WPA hashes with my pwnagothci however since I need to focus on getting this webserver complete first, I'm going to get back to it later. Thanks for reading!
