Headless installation https://github.com/FoldingAtHome/fah-client-bastet/discussions/214 See also the guide on the download page. Thank you, this was very helpful. I tied my existing passkey to my account and started the folding. It appears to be working. There also appears to be a way to dynamical...

Thanks! This was the fix to get the service started successfully. The logging isn't generating anything so I may need to specify my account-token in the config.xml. I'm reading the git url on how to obtain it.

This is the syntax I tried:

Code: Select all

<config>
        <passkey v='[passkey]'/>
        <team v='[team]'/>
        <user v='[user]'/>
<config/>

For a headless install you really only need account-token

Is there documentation on how to specify account-token? What about specifying items like core usage, etc?

Hello, I have seen many posts asking how to configure certain parameters in the config.xml file. Is there a fully detailed document on this yet? I have built the rpm and installed the package on Alma Linux, however the service fails to start after attempting to add a passkey, user, and team. This is...

Thanks so much! I think that is exactly what I needed. I added the cpus v='1' line to my config.xml file and now fahclient is only using 1 core. I will look into the remote access configuration as well as time permits, but it appears the stanza needs to read:  <slot id='0' type...

Andrew

Hi folks, Thanks for the replies. I will try to elaborate on what I am attempting to do. I am looking to control exactly how many cores folding@home leverages on my server. For example, running nmon (system monitoring utility) currently returns that FAH is using 2 cores. Here is also output from top...

Hi folks, I am looking to see if anyone is aware of how we can control the core usage using the fahclient on Linux? For example, if I want to explicitly run fahclient on 1 core, 4 cores, etc. Historically, I have performed this by editing the /etc/fahclient/config.xml file and adding a slot id on a ...

Hi folks, I think there are some opportunities for improvement on the main F@H website, specifically on the Linux Install and Command Line sections. There are commands listed with old versions of the F@H client, in addition to command line options that to my knowledge, no longer function as intended...

Andrew

Hopfgeist - That's funny, I was looking in my F@H install directory, and had the v7.6.13 rpm sitting there, so it would seen as if something has changed since that version.

Andrew

Hopfgeist, could you expand on the 'name matching' work flow for my understanding? I'm curious what you mean by this.

Thanks!

Andrew

Appreciate the feedback, Whompithian! At first glance, I think this may ultimately resolve my issue, if I move to systemd for the service based off your link. My understanding is that /usr/bin/FAHClient is not open source, so I have had some challenges debugging it. Before your post, I made some min...

Hi folks, I recently updated to the latest v7.6.21 of Folding@Home, running on CentOS 8.x. Post-upgrade, running './FAHClient status' and './FAHClient stop' do not function. After some investigation, it appears the PID file defined in the logic is not being created on startup of FAH (--pid-file=/var...
