[Beowulf] Cluster Hat

[Faraz Hussain]

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.
