Devices - 2024.2 English - UG1700

After an AMD platform is found, the application needs to identify the corresponding AMD devices.

The following code demonstrates finding all the AMD devices, with an upper limit of 16, by using API clGetDeviceIDs .

cl_device_id devices[16];  // compute device id
char cl_device_name[1001];
    
err = clGetDeviceIDs(platform_id, CL_DEVICE_TYPE_ACCELERATOR, 
  16, devices, &num_devices);
    
printf("INFO: Found %d devices\n", num_devices);
    
//iterate all devices to select the target device.
for (uint i=0; i<num_devices; i++) {
  err = clGetDeviceInfo(devices[i], CL_DEVICE_NAME, 1024, cl_device_name, 0);
  printf("CL_DEVICE_NAME %s\n", cl_device_name);
}
