Busy times

The BOINC Raspberry Cluster is still alive and crunching, no worries. The last two month have been extremely busy in the office. With the summer season started there was no time to update the blog. Unfortunately I found out that…

Overclocking the Pi4

Lately one of the POE HATs fan failed and it took a while to source spare parts for repair. In the meantime I noticed that the Raspberry Pi was running stable right below 60°C on full load. Thanks to the…

BOINC Cluster Benchmarks April 2021

April was very busy for me and I did not really get my hands one the cluster. So the Raspberry Pi Nodes got time to crunch pretty undisturbed. Only thing to mention is that the fan of one POE HAT…

BOINC Cluster Benchmarks and Updates March 2021

Finally I was able to finish print and assembly of the cluster rack case. Some missing parts needed to be fetched which was a sometimes a little complicated because of COVID restrictions. Instead of ordering things via Amazon prime I…

BOINC Cluster Benchmarks February 2021

In February the Cluster had a couple of downtimes since the build of the 19″ Pi rack has begun. As you may have heard I gifted myself a Prusa Mini+ 3D Printer in order to „print“ a special 19″ case.…

BOINC Cluster Benchmarks January 2021

As today the Raspberry Kubernetes Cluster consists of 4 Raspberry Pi 4 (8GB RAM) and runs on Raspberry Pi OS (64 Bit) beta. The Cluster is build with Rancher K3S. Each BOINC pod has assigned 3 CPUs and 6GB of…

Cluster preparations

The Raspberry Pi4 are now up and running. Now there is some customizing needed before we can start settting up the kubernetes cluster. First a member of a cluster a called node. Each kubernetes cluster has a master node which…

Cluster Housings

As I wrote before it es difficult to find the right case for the BOINC Cluster. There are lots of options on the market regarding those cases. The Waveshare PoE HATs with their GPIO extension are limiting the choices of…

Shipments have arrived

Finally all orders have arrived. Raspberrys and Heatsinks had to be sourced different than the Ubiquiti switch and mircoSD cards. Luckily someone just started distribution of Waveshare PoE HATs here in Germany. So those did not need to ship around…

Hardware considerations

So let’s try to build a BOINC Kubernetes Cluster on Raspberry Pi 4 Computers. What do we need for that? All Rasperry Pi 4 Model B Computers come along with a ARM Cortex A72 CPU (4 Cores), onboard Gigabit Ethernet,…
