Newbie with headless Linux server has some questions

[Tetmohawk]

Hey, I just set up a new AMD Ryzen system and wanted to do Folding@home. Downloaded rpms per the site instructions and everything seemed to run great for several hours. I would get things like this:

06:04:25:WU00:FS00:Upload complete
06:04:25:WU00:FS00:Server responded WORK_ACK (400)
06:04:25:WU00:FS00:Final credit estimate, 1992.00 points
06:04:25:WU00:FS00:Cleaning up

I'm assuming calculations got finished and things uploaded properly.

Then I started getting stuff like this:

06:18:31:WU01:FS00:Connecting to 65.254.110.245:8080
06:18:31:WARNING:WU01:FS00:Failed to get assignment from '65.254.110.245:8080': No WUs available for this configuration
06:18:31:WU01:FS00:Connecting to 18.218.241.186:80
06:18:33:WARNING:WU01:FS00:Failed to get assignment from '18.218.241.186:80': No WUs available for this configuration
06:18:33:ERROR:WU01:FS00:Exception: Could not get an assignment
06:29:36:WU01:FS00:Connecting to 65.254.110.245:8080
06:29:37:WU01:FS00:Assigned to work server 128.252.203.9
06:29:37:WU01:FS00:Requesting new work unit for slot 00: READY cpu:5 from 128.252.203.9
06:29:37:WU01:FS00:Connecting to 128.252.203.9:8080
06:29:37:ERROR:WU01:FS00:Exception: Server did not assign work unit

So is it just as simple as there aren't any work units to get? I also noticed that the log files and my system date were off. Looking at some stuff here it seems that the log files are in UTC which jives with what I'm seeing. Is that correct?

Finally, any good sources for configuring a headless Linux system. The documentation says to look at FAHClient --help which I did, and that was useful. But anywhere else?

Thanks in advance for answering some newbie questions!

Welcome to the F@H Forum Tetmohawk,

This shows that you have successfully downloaded and completed a WU:
06:04:25:WU00:FS00:Server responded WORK_ACK (400)
06:04:25:WU00:FS00:Final credit estimate, 1992.00 points

I can see from your log messages that you have setup 5 CPUs. Drop it down to 4 and you will be getting WUs. Reason is that 5 is a prime number larger than 3 and it can cause issues while folding protein due to domain decomposition issues. Simply but, the protein can't be divided up nicely to fold on 5 CPUs.

Can you please post the first ~100 lines of your log file so we can see what the FAHClient sees hardware wise and how you have configured it? Also, what are you looking to configure for your headless system?

Thanks for your help! I've included the /var/lib/fahclient/log.txt file below. I noticed stuff about the GPU so I've installed opencl and will try that out. In general, I would think I could use any number of cores and the software would adjust accordingly. Things are running now. Also, is there a way to set it up so it runs continuously? I have access to the web server and I can select idle or when working. Right now it's set for when I'm working. So how does it know that if it's headless? So at night it doesnt' work at all. I want this to be an always-on server. It's headless and I don't use it as my desktop system. And it will have other things on it soon so I don't want it to be confused with when it's idle or isnt'. I guess I could set it for when I'm working and do a cron entry to wget 127.0.0.1:7396 periodically so it thinks I'm working. Anyway, thanks again and I look forward to helping the project out more.

Please note that your GPU, Nvidia GT218 doesn't have OpenCL 1.2 and Double Precision so can't fold: https://www.techpowerup.com/gpu-specs/geforce-210.c2020

Since you're running a CPU slot only, I know that under Windows you can run it as a service. I think you can do the same with Linux too (not sure how it is done).

If you want to fold on your CPU 24/7, simply select Full power and that's it.

Thank you for the feedback. I'll take a look at the full power setting. And for your information, when you install the Linux version it automatically sets it up as a service (daemon). Thanks again for your help.

On a side note, I feel this should really go to one of the main forum... This is actually a technical question.
