c++ - how do i get opencl to run on my gpu -


i using tutorial http://www.obellianne.fr/alexandre/tutorials/opencl/tuto_opencl_codeblocks.php gpu radeon hd 6970 , amd app , drivers date os windows 8 when run code in tutorial recognizes cpu

looking through source code of project, see following lines:

cl_int result = clgetplatformids(num_entries, platforms, &available);  err = clgetdeviceids(platforms[0], cl_device_type_all, maxdevices, deviceids, &numdevices);

the code querying 1 platform in system devices. don't know platform is, gpu devices in different platform cpu devices, , platforms vary depending on manufacturer responsible (intel, amd, nvidia, etc.).

you'll need modify code query devices each platform id returned, not first platform.
