17th of April

10 million 

The cluster passed 10 million credits for Einstein@home about two weeks ago, but I didn't notice at the time. Its had a separate account since April 2016, which means it has taken around 5 years to reach this point.

 


 

Rearranging

Two of the Pi3 nodes were retired and two Pi4 (8GB) nodes replaced them. That increases the flexibility of the cluster as the Pi4's are faster and have more memory. The cluster now consists of:

3 x Pi4 (2GB) as support nodes

4 x Pi3 compute nodes

2 x Pi4 (4GB) compute nodes

6 x Pi4 (8GB) compute nodes

The recent changes at Roesetta@home have meant the Pi4 4GB are no longer able to run their work so I will swap them for Pi4 8GB, after I buy some more micro SD cards.

I am rather new to thisbut my pi4 with 4GB of ram gets rosetta@home work units to run all the time. At the moment it runs folding@,home and boinc with Rosetta and mlc@home. It has a 250GB SSD, if that changes anything. No virtual ram. The swap settings are at their defaults. It was just a test to see how it goes, since I am planning to set up a few of these machines at my cottage later to run 24/7 the whole year. Arjen

There is a message thread on the Rosetta@home message boards about this. See https://boinc.bakerlab.org/rosetta/forum_thread.php?id=14533

The project were fiddling with the required memory and disk parameters for work units and it seems they set them rather high. They have since revised them down a bit to enable the 4GB devices to get work.
