Farm status
Everything is off. Has been for the last few weeks due to building repairs and painting. They should be finished today so I will look at restarting the farm once the weather cools down tonight. Its currently 34 degrees C.
Ampere Mt. Snow
I got a quote for a Ampere Computing Mt Snow. They're not cheap, but then I didn't expect it to be. I asked for the Q80-30 CPU (80 ARM v8 cores running at 3.0GHz). Its slightly slower than their top of the line model (3.3GHz) but uses less power.
I have to get the quote updated as its only got 128GB of memory which I don't think will be enough for 80 cores, I will bump it up to 256GB. I also need to clarify what networking it has built in, hopefully 10GbE otherwise I will have to add a network card.
Other news
I'm looking to off load the Intel GPU machines from the farm. Hopefully I can get some money for them and maybe I will add another Ryzen 5900X into the mix to make up for the lost CPU cores, although most computing projects are using GPUs these days.

CPU only
Doing Rosetta overnight
Intel GPUs
Off
Nvidia GPUs
Three running Einstein, Milkyway and Rosetta overnight
Raspberry Pis
Running Einstein and Rosetta

Other news
I had to downgrade another of the Nvidia GPU machines to kernel 4.19 so I could use its GPU. The "GPL Condom" changes in the 5.9 kernel are causing me grief. I have one Nvidia GPU machine still running the 5.9 kernel which can no longer use the GPU for compute. There is a 455 driver from Nvidia which might work but its in the experimental stage in Debian.
I finally received the 2nd Ryzen 5900X CPU today so I'll be swapping out the second 3900X for a 5900X today.
GPU upgrades
I mentioned in my 19th of December 2020 post that I had plans to upgrade the graphics cards. I bought 4 x Seasonic 850w power supplies as the current machines only have 550w power supplies.
I haven't decided what Nvidia graphics card to get. I am leaning towards the RTX 3060 Ti although there are rumours of an RTX 3060 Ultra. I am waiting on the official announcement so I can compare them.
