Introduction
|
|
============
|
|
|
|
I'm working on building a cluster of Raspberry Pi CM4 compute blades. I plan on
|
|
using the cluster to learn a bunch of stuff, but I need to be able to provision
|
|
the blades automatically. This repo is my work in that area.
|
|
|
|
There are some assumptions made:
|
|
|
|
1. All the systems involved are Debian-ish systems, particularly Ubuntu. The
|
|
build system here will assume this. It may work on non-Ubuntu apt-based
|
|
systems. For non-Debian systems, I've also been working on including
|
|
container builds that may work.
|
|
2. The primary target for this setup is Ubuntu 22.04. This needs to be
|
|
validated still.
|
|
|
|
There are three types of systems:
|
|
|
|
- ``dev`` indicates DEV compute blades.
|
|
- ``tpm`` indicates TPM compute blades.
|
|
- ``gw`` indicates the gateway system, which may perform other functions.
|
|
|
|
The `computeblade docs <https://docs.computeblade.com/>`_ has a description of
|
|
the different blade types.
|
|
|
|
Below is a diagram of the planned system.

Hardware
|
|
--------
|
|
|
|
The hardware isn't slated to arrive until September at the earliest. I am
|
|
leaning towards having the 1TB NVMe drives go with the AI modules, and use
|
|
the gateway system as the storage machine if needed.
