Time to create a supercomputer!
Actually, that is exactly what happened. I'm an IoT lecturer, and this was a gift from a local company. They are currently sleeping safely in my home office, but tomorrow they will go to their new home, and wait patiently for students to come up with projects (or until I assign them projects)
A supercomputer is only as good as its software.
What is your application that could take advantage of all the RPi processing?
How? Why? What!?
