Who has a no-gpu system?

[promeneur]

Do I need opencl to fold ?

[promeneur]

With fah-control when I try to replace "gpu=false" by "gpu-beta= true" then it is not recorded.

[promeneur]

Here is my setup

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

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

<!-- User Information -->
<passkey v='<passkey-value>'/>
<team v='<team-value>'/>
<user v='<id>'/>

<!-- Folding Slots -->
<slot id='0' type='CPU'/>
<slot id='1' type='GPU'>
<pci-bus v='0'/>
<pci-slot v='2'/>
</slot>
</config>

ok i set the good flag but we need opencl
then
i installed opencl (beignet supplied by opensuse in standard repo), opencl1, fetch-fahclient-devel wich supplies a link "libopencl.so" -> "libopen.so.1"
then
i get this when starting fah client

Do I need opencl to fold ?

Yes, you need OpenCL to fold. It should be available from Intel as well as the video drivers needed. The open source drivers probably will not work.

I understand the support people are working on exact requirements, but in general you will need recent proprietary drivers and the related OpenCL support.

There's currently no WUs small enough available for Intel iGPUs ...

Any hope to get a WU for my igpu ?

[HD Graphics 630] should be supportable, but I have to have the latest Intel driver on my Windows system. I don't know how (or if) you can do that on Linux.

openSUSE 15.3

We get the version 21.43.21438.

This is the latest version (21.46.21636) - 3
