Hello Daniel,

Could you please make sure that your program selects Intel OpenCL platform during initialization. It looks like you have multiple OpenCL platforms installed on your system (since you are mentioning AMD and NVIDIA).

Thanks,
Yuri

Yes, exactly. To work with the Intel OpenCL kernel debugger you should use Intel platform.

Thanks,
Yuri

Here is some utility code that I helped out on it shows you how you can make sure and get a context for the correct platform and vendor using the Khronos C++ wrapper which you can easily modify to work with the c version as the opencl wrapper will return the base data.

You can either use the clCreateContext with the vendor enum or use arguments version.

Note: This code isn't meant to handle every single possible option (clearly as we don't handle IBM, or Img Tech, or any others). I have included it here as it should show you how to write something similar for yourself so you can never/almost never worry about this stuff again and get to coding.

Also it is way shorted with the C++ wrapper.

If you want to see the rest it is at: https://github.com/smistad/OpenCLUtilities
enum cl_vendor {VENDOR_ANY,VENDOR_NVIDIA,VENDOR_AMD,VENDOR_INTEL};

cl::Platform getPlatform(cl_device_type type, cl_vendor vendor) { // Get available platforms cl::vector platforms; cl::Platform::get(&platforms); if(platforms.size() == 0) throw cl::Error(1, "No OpenCL platforms were found"); int platformID = -1; if(vendor != VENDOR_ANY) { std::string find; switch(vendor) { case VENDOR_NVIDIA: find = "NVIDIA"; break; case VENDOR_AMD: find = "Advanced Micro Devices"; break; case VENDOR_INTEL: find = "Intel"; break; default: throw cl::Error(1, "Invalid vendor specified"); break; } for(unsigned int i = 0; i < platforms.size(); i++) { if(platforms[i].getInfo().find(find) != std::string::npos) { try { cl::vector devices; platforms[i].getDevices(type, &devices); platformID = i; break; } catch(cl::Error e) { continue; } } } } else { for(unsigned int i = 0; i < platforms.size(); i++) { try { cl::vector devices; platforms[i].getDevices(type, &devices); platformID = i; break; } catch(cl::Error e) { continue; } } } if(platformID == -1) throw cl::Error(1, "No compatible OpenCL platform found"); cl::Platform platform = platforms[platformID]; std::cout << "Using platform vendor: " << platform.getInfo() << std::endl; return platform; } cl::Context createCLContextFromArguments(int argc, char ** argv) { cl_device_type type = CL_DEVICE_TYPE_ALL; cl_vendor vendor = VENDOR_ANY; for(int i = 0; i < argc; i++) { if(strcmp(argv[i], "--device") == 0) { if(strcmp(argv[i+1], "cpu") == 0) { type = CL_DEVICE_TYPE_CPU; } else if(strcmp(argv[i+1], "gpu") == 0) { type = CL_DEVICE_TYPE_GPU; } i++; } else if(strcmp(argv[i], "--vendor") == 0) { if(strcmp(argv[i+1], "amd") == 0) { vendor = VENDOR_AMD; } else if(strcmp(argv[i+1], "intel") == 0) { vendor = VENDOR_INTEL; } else if(strcmp(argv[i+1], "nvidia") == 0) { vendor = VENDOR_NVIDIA; } i++; } } return createCLContext(type, vendor); } cl::Context createCLContext(cl_device_type type, cl_vendor vendor) { cl::Platform platform = getPlatform(type, vendor); // Use the preferred platform and create a context cl_context_properties cps[] = { CL_CONTEXT_PLATFORM, (cl_context_properties)(platform)(), 0 }; try { cl::Context context = cl::Context(type, cps); return context; } catch(cl::Error error) { throw cl::Error(1, "Failed to create an OpenCL context!"); } }

Let me know if you have any quesitons

Hi Daniel,

Just to be clear, does your code work with the Intel OpenCL device without debugging?
