31st of October

Farm status
CPU only
Running some Einstein and Asteroids work

Intel GPUs
Off. Did some Rosetta work earlier in the week.

Nvidia GPUs
Off. Did some GPUgrid and Rosetta earlier in the week

Raspberry Pis
Running Einstein BRP4 work

Other news
Rosetta ran out of work. One of the nice things about their work units, when you can get them, is they run for 8 hours so it makes it easier to run work overnight.

I mentioned in my last blog post that I was looking at updating the SSD's in the CPU only machines. I have ordered a couple of 1TB Sabrent Rocket SSD's to go in them. Hopefully they will alleviate the I/O bottleneck when running Rosetta work.

Linux bugs
I updated the Intel GPU machines with the latest kernel available in buster-backports, which is 5.8. After applying the updates the machines now switch to 640x480 resolution when one logs out. It switches back to the correct resolution (1680x1050) when I log in, but its really big (and annoying) on a 22 inch monitor. The Nvidia GPU machines aren't doing this.

There is a 5.9 kernel already in the testing release, so hopefully that will fix it. The 5.10 kernel is meant to be a long-term release (that is they'll fix bugs for a couple of years) so I think they will push the 5.10 kernel through fairly soon now that development on it has completed.

Update 3rd of November
Sabrent Rocket SSD's installed in both of the Ryzen 3900X machines. They seem faster than before.
