About the OpenCL category

Please post here questions about OpenCL library in GGEMS.

Hello developers and users,
I have installed opencl on the server, which is cuda-opencl. I checked through clinfo and found that the installation was correct, while nvidia-smi and others were all working properly. However, when I entered Docker and tried to run the example, the following error was reported. I hope someone can help me understand the specific reason for this.
Best wishes!
