Chris Bensen on Raspberry Pi and clusters

Posted by jpluimers on 2022/12/29

Oracle’s Pi Supercomputer

In 2019 ans 2020, [Archive] Chris Bensen and his [Archive] Oracle Groundbreakers team built a really large Raspberry Pi cluster of more than 1k pies, all network booting to become a cluster. It was for instance covered in the [Wayback/Archive] Building the World’s Largest Raspberry Pi Cluster – DZone IoT.

On his [Wayback/Archive] personal blog, he wrote a few posts like [Wayback/Archive] Chris Bensen: Raspberry Pi Overlay Root Filesystem and [Wayback/Archive] Chris Bensen: Get MAC Address for a Pi Cluster.

It made me also bump into [Wayback/Archive] Building the world’s largest Raspberry Pi cluster early 2020,

Since that wast right after the start of my rectum cancer treatment which lasted longer and, because of I got metastases a few months after radiation treatment, required more treatments than anticipated, I put a note in my bog drafts and kind of lost track.

So I was glad that in fall 2021, I bumped into the draft and found an almost year old post [Wayback/Archive] Chris Bensen: All Raspberry Pi Super Computer Posts in One Spot which is an index in all the blog posts and videos that Chris and his team produced on this project.

I then also learned the cluster had been shown on [Wayback/Archive] Oracle OpenWorld 2019, Breakthrough Starts Here and was covered in the [Archive] Top 10 Raspberry Pi Projects of 2019 | Tom’s Hardware (where I got the [Wayback/Archive] Oracle World 2019 having the 1k+ node Raspberry Pi cluster on display picture shown on the right from).

In autumn 2021, the cluster was missing some pieces.

I still thing this is a great project, even though by now even better versions of the Raspberry Pi are available.

So I was kind of shocked that Chris Bensen posted these in the midst of the second year of the corona crisis showing the [Wayback/Archive] second picture on the right and [Wayback/Archive] hey, why is here exactly one red part in here where all others are blue?:

The autumn 2021 fix was re-adding missing pies and one missing blue part becoming red.
