16th of July

Marks Rpi Cluster cluster continues to run 24/7. Last week Einstein@home ran out of BRP4 work so the cluster went quiet. I had to resume Asteroids@home work on the eight Pis that have the project. Work resumed flowing again on Friday and the cluster is playing catch up.

We're still waiting on Raspberry Pi OS updates to match Debian 12 (Bookworm). I only had a couple of quirks when updating from Debian 11 to 12 on my x86_x64 machines. One was with ntp not being available. The default is systemd timesyncd or one can install chrony or ntpsec. The other was around the GPU drivers being a mix of both non-free and contrib, but that won't effect the Raspberry Pis.

I've read a few of your posts and they are very interesting, thanks you for posting! I've been also using RPIs for BOINC, mostly for Einstein and Universe. What kind of cooling do you use?

I used to use a custom designed case that held 4 Pis side by side with 40MM cooling fans on top powered via USB. I called it the Pi^4 (Pi to the power of 4) case. You can see images of it from the 4th of April 2021. I was using 4 port USB power bricks but they kept burning out.

These days I an using the Bitscope Edge Cluster 12 which holds 12 Pi and provides power and cooling. You can see them in my 26th of July 2022 post (and a few more posts after that).
