Last week I added one of the Pi 3B’s back into the cluster. I thought I would see how it goes running the Seti Multibeam app. It was processing then around the same amount of time as the Einstein BRP4 work units (about 11 hours). Its now back to running Einstein work.
I have just added another Pi3B back into the cluster. That brings the cluster up to 12 x Pi3B+ nodes and 6 x Pi3B nodes. Unfortunately the ARM processors on the Rpi aren’t that fast. The Pi3B+ are about one hour quicker than the Pi3B. By comparison the i7-6700 can do them in one hour, which makes the Pi3 about 1/12th of speed of an Intel machine.
