Linux CLI client, no X

Postby vprelovac » Thu Jul 12, 2018 6:12 pm

Hi all

I have 10x1080ti that I want to contribute.

Is there a way to run FAH as CLI only? I do not have X server. Using ubuntu 16.04.

FAHClient installs and runs as a service. You can manage it with FAHControl or WebControl if you have a GUI but that's not required. It can also be managed by sending and receiving telnet messages or equivalent. The service listens on port 36330.

Thanks Bruce. Is there a document explaining how to contribute GPU in this mode. I am completely new to the project.

I don't know of one that has been published.

There is a help file that can be obtained using the telnet interface but may of the options will be unfamiliar to you. Reading the questions and answers here on the forum will help.

FAHClient makes some reasonable assumptions when it sets up an initial configuration, so you won't need to do much except to define your folding name and an optional passkey.

Please note the following instructions should work on any Debian version of Linux but you may have to adjust them if you're using some other distribution. I use ubuntu 18.04 and I know they work for it.
You would, of course, have to install a fairly recent version of the nvidia driver and opencl. Depending on your version of linux those may be in your current repositories.
Code: Select all
sudo apt install nvidia-390 ocl-icd-opencl-dev
If not you may have to add a repo that has the necessary software or download & install from http://www.nvidia.com/drivers

Very basically, you would need to create a config.xml file with your configuration:
e.g. for you to copy and modify to suit your needs ... Select All may not work but you can highlight the contents inside the box and copy/paste it to your editor.
Code: Select all
<config>
  <!-- Folding Core -->
  <core-priority v='low'/>

  <!-- HTTP Server -->
  <allow v='127.0.0.1,192.168.2.100-192.168.2.149'/>

  <!-- Network -->
  <proxy v=':8080'/>

  <!-- Remote Command Server -->
  <command-allow-no-pass v='127.0.0.1,192.168.2.100-192.168.2.149'/>

  <!-- Slot Control -->
  <power v='full'/>

  <!-- User Information -->
  <passkey v='your passkey'/>
  <team v='your team number'/>
  <user v='your folding user name'/>

  <!-- Folding Slots -->
  <slot id='0' type='GPU'>
  </slot>
</config>

Change the lan's IP range and User Information, using an editor of your choice, to look like your lan and identity and add slots as required. Do not remove 127.0.0.1 or the following comma.
Caution: be very careful when editing ... the .xml parser of FAHClient does not like mistakes and may refuse to run until you correct them.

Move your config.xml to /etc/fahclient before you actually install FAHClient ... the installer will pick up on the fact that your config is already there and won't ask for that information assuming you're using the .deb installer:
Code: Select all
sudo mkdir /etc/fahclient
sudo cp config.xml /etc/fahclient

Install the FAHClient .deb

If you told the installer to start folding automatically (the preferred method - creates a service that starts after a reboot) then it should be running (reboot if it's not) and you can use commands like:

FAHClient --send-pause
FAHClient --send-unpause
FAHClient --send-finish
sudo service FAHClient stop
sudo service FAHClient start

If you told the installer not to start automatically then all you need on the command line is:

FAHClient

The folding log is called log.txt and should be in /var/lib/fahclient

p.s. if you don't already have one you can get a passkey @
https://apps.foldingathome.org/getpasskey.py

My word 'reasonable' applies to simple systems -- since Folding@home was designed to run on @home systems. They're reasonable for CPUs that support up to 8 or 12 threads with the assumption that there are 0 or 1 or 2 GPUs. For more complex systems (like yours) you may choose to modify the original setup but that initial setup should work pretty well until you have a plan of how you might want to alter it.

The help file for the telnet interface is:

If you use the options of either FAHClient or of the telnet interface to make changes, you will avoid getting trapped by a minor xml mistake.

In order to get the GPUs running you need a minimum of X installed, else the consumer driver for consumer hardware will not work. If you have “professional”versions of NV hardware life would be easier.

I run a headless GPU box 8000 km away and managed to install VNC server which brings just enough X with it to start correctly and allow the driver and FAH to play together. Then as Bruce mentioned I use the telnet interface from my mobile device to check the progress, FAHControl will do it too (as it also works via the same telnet communication)
