I managed to pickup some GPU work from GPUgrid. They’ve been concentrating on their multi-core CPU app and GPU work has been in short supply. This time I got some short and long work units which have been running fine. This exposed a problem with my app_config file that wasn’t working for the short work units. I use an app_config file to allocate a whole CPU thread to their GPU work units which makes then run quicker. I resolved the issue with it.
Asteroids and Einstein both passed 50 million credits. Asteroids gave another badge as a result. I have been running Einstein overnight on the i7-6700’s. It sometimes takes a few goes to get the gravity wave work and I have to manually intervene until they’ve got tasks.
I was concentrating on Seti work to keep it ahead of Asteroids and Einstein however they ran out of work units this weekend so its back to Asteroids for a bit. Seti gives less credit than the other two therefore it takes more processing to keep the credit scores aligned.
The Bramble increased to 12 crunchers and I used all 3 of the Mk II Pi^4 cases I had printed off. See MarksRpiCluster for details.

Winter weather has arrived allowing numerous machines to run constantly. I’ve been concentrating on Einstein work but have the Intels running down so the Nvidia GPUs can be used. Due to the power available (domestic grade power circuits) I can’t run all of them at once, even if the weather allows me to.
Additional USB chargers and some Y split fan header cables arrived, as did three Pi3 model B+. I have swapped the NFS server over. One has been put into service crunching, that gives 11 compute nodes for the moment. I am waiting for the L shaped power cables to be able to get the remaining one into my third Pi^4 case.
I haven’t worked out what to do with the remaining Pi2 and Pi3 model B’s, but I do have the prototype Pi^4 case with the 40mm fans that I could use to get some of the Pi3’s going. The Pi2’s don’t need active cooling so can run with the top off their case. I will need more network cables and SD cards to be able to use these. I really should have another look at NFS booting them. Or I could give the Pi2’s away.
BOINC testing
We’re testing 7.10.2 at the moment which is a release candidate. It looks like it will finally fix the BOINC event log (aka messages) stuffing up the time format under Linux. It also moves the boinc data directory in Linux to be in /var/lib/boinc with a symlink to the old one at /var/lib/boinc-client.
