"If you were plowing a field, which would you rather use: Two strong oxen or 1024 chickens?" -Seymour Cray
Terrible Cluster is possibly the worst example of a computing cluster imaginable. Four Raspberry Pi Zeros each offer up their puny decade-old ARMv6 core and meager 512MB RAM for computation. Meanwhile, a Raspberry Pi Zero W head node tries in vain to direct traffic across an inappropriately named "fabric" using USB 2.0, host a distributed filesystem, and control power to the compute nodes. The Terrible Cluster backplane board powers and connects all five Pis together using a Cypress USB 2.0 hub and four USB power controllers. Through hole micro USB vertical plugs allow 6mm spacing between nodes which results in a high density compact system that fits easily in the e-waste recycling bin of your local electronics retailer, under the tire of a passenger vehicle, or down the bore of an abandoned oil well.
I created Terrible Cluster to further my experience working with cluster systems and to play with strategies for cluster deployment of firmware and applications. This hackaday.io project is a fantastic opportunity to strengthen the above self-delusion through accumulation of Internet Points in the form of views and skulls.
It is difficult to have even a shred of hope that the edifice of western civilisation can survive this project. It was already tottering, but this is the final straw. If only you had waited for the USB-D connector.
