PMean: Super Pi, a group to teach cluster computing using the Raspberry Pi
If you want to learn cluster computing and you didn’t have easy access, you had two choices. You could simulate a cluster computer on your laptop, or you could buy time in the cloud. There’s a third approach, build your own cluster computer system using several Raspberry Pi computers. Continue reading
