I didn't come up with this, but I remebered that it was posted some time ago:

To get work with aarch64 you need in /etc/boinc-client/cc_config.xml a alternate platform string.

<options>
<alt_platform><span class="mark">arm-unknown-linux-gnueabihf</span></alt_platform>
</options>

Hope that helps,

Hello Keith,

since U@H is CPU only, the CPU and the OS are the two biggest factors.
Currently Linux systems are about factor 2 faster than Windows. I tested this on my own and it is software dependent.
But since you use Ubuntu Bionic and Focal, there should be only marginal differences.

Technically your Ryzen 9 3950x (same I have) is a beast on its own. By cores it should be 133%, by frequency 155% compared to your TR 2920x.
But ZEN2+, specially on the 3950x with
- the PBO (better heat control via more temp read areas),
- the better Mainboard upscaling with power supply and
- no cap on memory speeds (main limiting factor on all 1xxx and 2xxx AMDs)

leads to 265% performance in your case. This is more than I expected, but maybe there is some deviation with tasks too.

This sounds amazing but I recognized the same with my change from Ryzen 7 1800x (fastest CPU when I bought it) to Ryzen 9 3950x (got my hands on the very first ones).
The tech scene was amazed about the real life performance of the Ryzen 9 flag ship.
When compared to TR even (e.g. Linus Tech Tips) came to the conclusion that the Ryzen 9 somehow killed all TR 1xxx/2xxx line up completly.

Hope than explains the part that xii5ku couldn't explain.

I don't think it is project-related at all.
Your BOINC client doesn't accept the input or it somehow recognized 12 threads/ cores.

20 of 22 machines are dry. No Wus anymore.
When will we get next WUs approximately?

That is from a lot of connections that are currently made to the server.
It works believe me. I have 21 computers working for U@H.
Give it some time and it will normalize.

It seems like there is a WU per CPU (or more precise on CPU Threads) limit as well. 8 cores/ 16 Threads seems to be 128. Hosts with 4 cores/ 4 threads = 32.

Hi,

don't think it is a problem only for you. And non-static IP adresses are common with ISPs. I get a new one assigned every 24 hrs or on restart of my router. So it is very common.

Not sure what the overall limit is, but I get max for my best machine of 128.

Hi,

I checked my logs too. I find similiar log entries (for all 20 pcs). Is the problem still present for you?

It fixed itself after about 5 hours for me. I had more details in the log:

Hope it was a temporary issue. If not the admin should take a look on it.
@Krzysztof: Was there an outage in the last 24 hours?

Hi,

do you have more informations? A task name would be great.
Reason I am asking is that I see no tasks for first user at all and a lot of cancelled for second user. Maybe server/ your client are kind of "out of sync".
