For Nvidia? It's an RTX 4060 and would be crippled if it had to use OpenCL.

Submitting to forum as instructed... but I'm not certain that this is the correct thread for this.

Thanks.

21:55:14:E :WU1631:The folding core did not produce any log output. This indicates that the core is not functional on your system. Check for missing libraries or GPU drivers. Make a post about your issue on https://foldingforum.org/ to get more help.
21:55:14:E :WU1631:Run did not produce any results. Dumping WU

The WU_STALLED error is often a false positive. The core indicates that it has stalled by exiting with code 127, but exit code 127 is also what the system itself uses to say a program cannot find a required library. The client will misinterpret that error for a stalled WU error.

Post the output of the following commands:

Code: Select all

$ cd /var/lib/fah-client/cores/openmm-core-26/centos-7.9.2009-64bit/release/fahcore-26-centos-7.9.2009-64bit-release-8.2.0
$ LD_LIBRARY_PATH=$PWD ldd FahCore_26

The output will show what libraries FahCore_26 has access to and what libraries it needs but does not have.

In the past the installation of OpenCL and the CUDA support libraries were linked, both needed to be installed for folding to work. Unless there has been a recent change, the CUDA support is not installed by itself.

ICD exposes required libraries to fahcore26/27.
It does not force FAH to use OpenCL

Something changed either with Nvidia drivers or with core26/27 that in some cases it now requires icd loader. It might even be OS changes

Posted: **Tue May 20, 2025 5:48 am**

I didn't know that! I just know that I don't need ICD to fold with CUDA with core26/27. So it must be an OS change.

Indeed it is quite random

Posted: **Tue May 20, 2025 6:07 am**

Based on discord discussions it also depends how the OS is installed: upgrade from previous release, initial install some time ago, fresh install.
In my case I did not need ICD on a 24.04.1 install from 2024, but needed it for a fresh 25.04 install...

Posted: **Tue May 20, 2025 12:13 pm**

I checked the absent libs using the

LD_LIBRARY_PATH=$PWD ldd FahCore_26

it showed that the OpenCL libs were missing. So I did this...

sudo apt install ocl-icd-opencl-dev

That was successful but FAH is running a core-23 work unit now. If I get a core-26/7 WU later and it's successful (or not), I'll post that.

Thanks everybody.

libOpenCL.so.1 must be installed for cores 26 and 27, older cores came with their own library. No further OpenCL components required if you just want to use CUDA.

F@H is currently working on a core-26 WU and everything appears to be going just fine.

Sincere THANKS to all who assisted.

Enjoy your Memorial Day weekend.

btw - it is running CUDA.

This first step is good!!!
A stable and bugfixed app is welcome!

Now.....Hip

Core26 is old news
Core27 is the sh*t now
HIP will probably be core28
