Marks Rpi Cluster continues running 24/7. The cluster is currently running Einstein@home work on all the compute nodes. Rosetta@home only had some python tasks which don't work on the Pi's.
The 5 x Pi3 nodes are running BRP4 work units (on 3 out of 4 CPU cores) at a time, so that gives 15 work units. The 9 x Pi4's are running a mix of BRP4 and Gamma ray work units on all 4 cores, giving another 36 work units in progress.
One of the Pi3's had a declining RAC (Recent Average Credit) compared to the other Pi's. Suspecting it was the micro SD card I re-imaged a new card and installed that last week. After a week of running the RAC is now climbing to be close to what the other Pi3's are getting. SD cards have a rudimentary wear-levelling mechanism so when its worn out it usually means all of the card is worn out. It wasn't giving any errors, just taking longer than the others to do the same thing.
