[Beowulf] 2 starting questions on how I should proceed for a correct first micro-cluster (2-nodes) building

[John Hearns]

I second OpenHPC. It is actively maintained and easy to set up.

Regarding the hardware, have a look at Doug Eadlines Limulus clusters. I
think they would be a good fit.
Dougs site is excellent in general https://www.clustermonkey.net/

Also some people build Raspberry Pi clusters for learning.
