Marks Rpi Cluster continues to crunch 24/7, although things have been a bit up and down due to the weather.


Updates
There was a Debian point release earlier this week, which they do every 3 - 4 months to update apps, this gave about 43 updates. The point release also bumped the OpenSSL version to fix a new vulnerability.

It was followed a day later with the Raspberry Pi kernel jumping from 5.10 to 5.15. Debian are still on the 5.10 kernel so the Pis are now more up to date.


Einstein@home news
Einstein@home decided to renew their interest in the BRP4 search that all my Pi's run. The project got new data from the Arecibo telescope and were running out of candidates for the FGRP5 search.

They have a new beta test BRP4 app (1.61) out which is somewhat faster than before, but still not as fast as the optimized BRP4 app written by user N30DG a couple of years ago. I'm still running the optimized app. They have also relaxed the validation of work units a bit, where two Intel iGPU work units would gang-up on the Pi and declare the Pi's result as invalid.

As a result of this renewed interest in the BRP4 search I have fired up my 5 Pi3's (which have been off for a while) so they can assist. They are slower than a Pi4 and can only run 3 tasks at a time due to their lack of memory but every little bit helps.
