Time build the physical computer, which will become a 4+1 Node super computer. To get the cases to stack, I’ve wrapped them into pairs with a bit of electrical tape. Here is Raspberry1 and Raspberry2 stacked
And again giving me 2 pairs of 2 Pi’s, this time Raspberry3 and Raspberry4
Take 1 10/100M Switch….
Add 2, 2 node Pi stacks….
Next we add a new comer to this project, RaspberryPrime, this is the 5th node in the stack and will be the coordinator of the 4 worker nodes
All the Pi’s are now wired to the switch…
And Raspberry Prime is located on top of the stack ready to control Raspberry’s 1, 2, 3 and 4
Cool eh ?
