Marks Rpi Cluster continues computing 24/7. The Pi3's are running the Einstein BRP4 work and the Pi4's are running Einstein and Rosetta work in a 50/50 split.

 

Pi^4 case

I finally managed to get my Pi^4 case and one of the power supplies cases back from the 3D printing studio. They printed off a sample top piece for the Pi^4 case but its not right. They also printed off a cover for the Mean Well power supply. Unfortunately they pulled the earth wire in the power cable off its spade lug so I will have to get it re-crimped before I can use it. In the mean time I have swapped the power cable with another one.

I'll be trying out the power supply shortly and if it works out will see if I can get 4 of the Pi4's going. I've got 9 sitting in their boxes ready to go along with fans. Its taken almost 6 months just to get the design and case back. I will have to find another 3D printing company to adjust the design, get another sample and if that is okay run off a couple of cases. It has been extremely frustrating.

Marks Rpi Cluster continues running 24/7. It currently consists of:

3 x Pi4 2GB support nodes

2 x Pi4 4GB compute nodes

3 x Pi4 8GB compute nodes

6 x Pi3 compute nodes

The Pi3 compute nodes are running Einstein BRP4 work. The Pi4 compute nodes are running Einstein BRP4 and Rosetta work in a 50/50 project split.

 

Other news

Still no contact with the 3D printing studio. I think I'll talk to the manager to see if I can get things moving. They don't answer the phone or reply to emails. I've not been pushing the issue as I need them to finish the design and print the parts for the Pi^4 cases and the power supplies. I need these to get the cluster up to 12 x Pi4 8GB and retire the Pi3's. I have cabling, power supplies and Pi4's ready to go if only I can get the cases sorted out.

The Raspberry Pi foundation did an about-face in the vscode repository. See my post "A little controversial".
