Marks Rpi Cluster continues to run 24/7. After my last post we had a few hot days so I allowed the cluster to finished off its current work and idle. It now back to crunching again although today was hot as well with the room they are in reaching 30 degrees C.

With the break in crunching for a few days my RAC (Recent average credit) has dropped from from 40k to 29k. The cluster is up to 19.7M credits so at the current rate it might take 3 days to hit 20M credits, assuming I don't stop again due to the heat.

Seeing as I can't get a hold of any more Raspberry Pis I have been looking at the Raxda Rock 5B online. It is an ARM single board computer, almost double the size of the Rpi and comes in a Pico-ITX format. It has 4 Cortex A55 cores, 4 Cortex A76 cores, a Mali G610 GPU and ton of connectivity. Given its combination of cores its probably best to crunch on the A76 cores and leave the A55 cores to run less demanding work. They come in 4, 8 and 16GB memory sizes. Unfortunately it doesn't have the software support that the Pi has so a number of things don't work under Debian. It can also run Android.
