Last year I built a 2-node cluster using Pi 3's. I setup a nfs
filesystem using a thumb-drive. I even installed SLURM scheduler. I
use it as a webserver through my home internet.
My to-do's are to make it publicly available for people to run small
jobs on it. I also want to install openmpi but I am not sure that is
possible.

Reading the Register article in the IBM IData system which was moved from
Daresbury Labs to Durham Uni, one of the comments flagged this up:

That's rather neat I think!
So how wmany of these can we get in a 42U rack ;-)
