Hi, it's not clear to me what you are running to produce this output. Can you please provide more detail?

If possible, can you also please provide information about the OpenCL devices in your system? You can find this by running clinfo, which is built as part of the OpenCL SDK, and is also provided by many OS package managers. For now, it's OK to just list the platforms and devices on your system with clinfo -l. For example:

$ clinfo -l
Platform #0: Intel(R) OpenCL
 `-- Device #0: 12th Gen Intel(R) Core(TM) i9-12900K

Minimum reproducible example:

#include <CL/cl.h>

int main() {
    cl_uint ret_num_platforms = 0;
    cl_int ret = clGetPlatformIDs(0, nullptr, &ret_num_platforms);

    return 0;
}

Also regarding hardware:

Platform #0: Intel(R) OpenCL Graphics
 `-- Device #0: Intel(R) Iris(R) Xe Graphics
Platform #1: Intel(R) CPU Runtime for OpenCL(TM) Applications
 `-- Device #0: 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz
Platform #2: rusticl
