Other news
The farm has been running Rosetta flat out as they continue their Covid-19 research. When it rains I have to shut the window and that means the heat builds up so I need to reduce the number of machines running which is why the Nvidia GPU machines are off quite often. The weather forecast for next week has rain for the whole week, heavy at times.

With the electricians coming next week I need to clear some space around power and network points around the house so haven't had a chance to look at the Ryzen 3900X build or the storage server. I had to adjust one of the shelving racks that sits above one of the power and network points which means moving computers around. They will also need access to the roof space so that means clearing access, one of which has a pile of (empty) suitcases in the way.

I will need to power everything down so all of the machines have to finish off any work they have. With Rosetta that can take up to 16 hours.


ARM based server
One of the ideas I am looking at is an ARM based server for compute purposes now that ARM is getting more support from developers. Both Ampere Computing and Marvell have new multi-core chips. The Ampere Altra boasts 80 cores and the Marvell Thunder X3 has 96 cores/384 threads. These are aimed at the data center market at the moment although usually its a matter of time before they make a workstation version.

Its a bit early (and expensive) to get one at the moment but something to keep an eye on developments. Both of these support DDR4-3200 memory, have disk/SSD support and PCIe expansion. The number one position in the Top500 Supercomputer list as of June 2020 is the Fujitsu Fugaku which is ARM based.

Pauses
We had a couple of pauses in computing since my last update. One due to the weather and the other due to electrical work.

The electricians need to replace network cabling in the walls/roof as its stopped working. The network cable tester thinks about half the wires are broken or disconnected and that was after replacing the sockets. The original cabling was done about 20 years ago and was Cat 5e so it will get updated to Cat 6a in the process.


Repairs and Outstanding work
I had to replace a case fan in one of the Intel GPU machines as it was making a fair bit of noise. The machine next to it is also loud so I need to replace it as well. Its a fairly quick fix but I need to get it to finish off its current work and that takes up to 16 hours.

The second Ryzen 3900X build is still sitting in boxes waiting to be assembled. Given its the weekend I might get time to look at it today, depending on family commitments.

The replacement server motherboard is still waiting to be installed. Its on the bottom of my list at the moment as the existing server is still working even with the memory in the wrong slots.

Rosetta news
Rosetta announced via twitter that they have created an antiviral protein. To quote their tweet on the 26th of June:

"We have some BIG NEWS: Researchers @UWproteindesign have succeeded in creating antiviral proteins that neutralize the new coronavirus in the lab. (These experimental drugs are being optimized for animal trials now)"

Most of last week they had little or no work so the farm was basically idle, possibly due to completing that task. More work has been forthcoming so the farm is running them now.


Other news
Most of this week was occupied getting the two networks combined into one new NBN connection. I ended up reinstalling the Raspberry Pis due to firewall issues on the Pi and not having a screen and keyboard so I couldn't access them. The Intel and AMD machines were easier because they have a screen and keyboard.

SpeedTest says I can get 45 Mbit downloads and 10 Mbit uploads now. File transfers are quicker but I don't feel they are 5 times faster than before.

Networking changes
I am in the process of switching to the NBN network. It should provide a higher speed internet connection. I've signed up for a 50 Mbit plan (50 Mbit download and 10 Mbit upload).

At the moment I have two DSL connections with two separate modem/routers which makes two separate local area networks. One has the x64 machines and the other has the Raspberry Pis. I will have to combine them into a single network.


Other news
I got a shipping notification for the 2nd Ryzen 3900X build. The rest of the parts should arrive next week. I already have the power supply and memory.

I've made it to 60th place on the Rosetta@home top participant list. I will be dropping back because today was rather warm (30 degrees in my computer room) and I have to reduce the heat being produced by the computers. I've set all of the Intel GPU and Nvidia GPU machines to no new tasks so they finish off the work they currently have.
