Folding Forum

Posted: **Sun Apr 19, 2020 11:13 am**

Hi, under Ubuntu 20.04, I downloaded from https://foldingathome.org/beta/ fahclient_7.6.10_amd64.deb which does not use systemctl but works and

Code: Select all

sudo gdebi fahclient_nnn.deb

and changed <gpu v='true'/> from false to true and <slot id='0' type='GPU'/> from CPU to GPU

Code: Select all

sudo nano /etc/fahclient/config.xml
<config>
  <!-- Client Control -->
  <fold-anon v='true'/>

  <!-- Folding Slot Configuration -->
  <cause v='COVID_19'/>
  <gpu v='true'/>

  <!-- User Information -->
  <team v='251999'/>
  <user v='ng0177'/>

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

It works! Here is the log. Did I make any mistakes?

By changing slot 0 from a CPU slot to a GPU slot while a CPU work unit was in progress, you caused the client to throw away the CPU work unit:

Code: Select all

[10:40:09:WARNING:WU00:No longer matches Slot 0's configuration and there are no other matching slots, dumping
[10:40:09:WU00:FS00:Sending unit results: id:00 state:SEND error:DUMPED project:14616 run:1777 clone:0 gen:35 core:0xa7 unit:0x000000289bf7a4d65e83237243786149

It would have been better to wait until the CPU work unit was complete before making the change.

And you won't be getting any more CPU work units. Is that what you intended? Instead of changing slot 0 to a GPU you could have created a new GPU slot, then you'd be folding on both CPU and GPU.

As far as the GPU goes, things seem to be working fine.

Finally, it looks like you don't have a passkey set up. You should get one, you'll get more points.

Thanks for that. Yes, I would like to use both GPU and CPU and modified /etc/fahclient/config.xml accordingly but a reboot is needed to take effect.

Code: Select all

<config>
  <!-- Client Control -->
  <fold-anon v='true'/>

  <!-- Folding Slot Configuration -->
  <cause v='COVID_19'/>
  <gpu v='true'/>

  <!-- User Information -->

  <!-- Folding Slots -->
  <slot id='0' type='CPU'>
    <paused v='true'/>
  </slot>
  <slot id='1' type='GPU'>
    <paused v='true'/>
  </slot>
</config>

A prerequiste for all this to work are the drivers and Cuda to be installed.

Code: Select all

sudo apt -y install nvidia-driver-440
sudo apt -y install nvidia-cuda-toolkit

Posted: **Wed Apr 22, 2020 7:23 am**

And it works under Ubuntu 18.04 likewise.

Hmm, where was the issue with Ubuntu 20.04?

It does work here since weeks on several machine (Ryzen & GTX), flawless from the USB stick, Focal Desktop Installation, then enable additional hardware drivers for Nvidia (440.xx).

Just one package may need to be installed additional manually in prior to FAHClient installation:

Code: Select all

#/> sudo apt update
#/> sudo apt install ocl-icd-opencl-dev

Dependencies for FAHViewer don't work on Focal 20.04, but doesn't matter to me, I control all my folding machines from one Windows Desktop with FAHControl ...

/etc/fahclient/config.xml is now much more verbose. Still

Code: Select all

<gpu v='true'/>

needs to be set manually and is not recognized automatically.

ocl-icd-opencl-dev seems to be part of cuda but good to know!

Ah, ok, that's right, but just a minor issue for a Linux user ...

From my point of view it's enough to delete the section with

Code: Select all

<gpu v='false'/>

the value true seems to be default. And if already editing "config.xml" manually, quickly add

Code: Select all

<slot id='1' type='GPU'>

underneath the CPU in slot section ...

And to be honest, on some Windows machines I had also manually to add/enable the GPU slot also from whatever reason ...

I would install the dev package:

Code: Select all

sudo apt install ocl-icd-opencl-dev

and reboot.

Yes indeed: -dev does the trick in Fedora. In addtion, GPU units for Covid-19 seem to be not available all the time.

Currently, there's a shortage of GPU WUs since the demand has exceeded the supply. Work is being done to increase the GPU WU supply.
