This is where Marks Rpi Cluster was on Christmas eve 2019. A total credit of 7,349,000 and a rather low average of 3,824 per day. The hot weather mixed with smoke pollution from the bush fires has kept the cluster idling.
Cluster nodes
Marks Rpi Cluster is ending 2019 with the following configuration:
10 x Pi3 model B+ compute nodes
10 x Pi3 model B compute nodes
2 x Pi4 model B (4GB) compute nodes
2 x Pi4 model B (2GB) support nodes
Other news
I have two Pi4's crunching for the farm (replacing a couple of Pi3's). The Pimoroni fan shim's that are cooling them are making noises from time to time so I can't see them lasting too long.
I still haven't managed to find a place that can provide a custom power supply capable of powering 4 Pi's. While I can find a bare-bones power supply it still needs wiring for the USB type C plugs, a fan header as well as needing a case.
2020 plans
I hope to replace all the compute nodes with Pi4 model B's. They're about 33% faster than the Pi3's and have more memory which makes them more flexible for future compute tasks.
Sort out the power supply situation which may require me to create a 3D printed case for the bare-bones power supplies.
Switch to 64 bit mode (aarch64) on the Pi4's. The current farm is running 32 bit (armhf).
