30th of May

Farm status
CPU only
Running Rosetta work.

Intel GPUs
All running Rosetta work.

Nvidia GPUs
Two running Rosetta overnight.

Raspberry Pis
Two running Rosetta. Six running Einstein.

Other news
I made it into the top 100 participants for Rosetta. As of this morning I was in 86th place.

The extra network cables arrived so I have used some on the machines that have multiple network cards. They now have two connections into different switches. I also had a 1M cable running between two switches and it was pulling one end so that got replaced by a longer cable.

I had a look around for some simple 2.5GbE switches and managed to only find one from D-Link. Most others have what they call multi-gig ports where it supports 1, 2.5, 5 or 10GbE speeds. The switches I am using at the moment have 8 x 1GbE ports and 2 multi-gig ports, one of which gets used as the up-link. You think there would be something like a 4 x 2.5GbE ports with a high speed up-link, or even an 8 port version.

Farm makeup
At the moment the compute portion of the farm consists of:
Type Number CPU GPU Memory
CPU only 1 AMD Ryzen 3900X (12C/24T) GT710 64GB
Intel GPU 6 Intel i7-8700 (6C/12T) Built-in 32GB
Nvidia GPU 4 AMD Ryzen 3600 (6C/12T) GTX 1660 Ti 32GB

That gives a total of 72 cores/144 threads and 384GB of memory. There is another Ryzen 3900X on order.
