I installed AMD APP SDK and here my problem. The OpenCL samples do not detect the GPU. HelloWorld give me this:[thomas@Clemence:/opt/AMDAPP/samples/opencl/bin/x86_64]$ ./HelloWorldNo GPU device available.Choose CPU as default device.input string:GdkknVnqkcoutput string:HelloWorldPassed!And here the clinfo output[thomas@Clemence:~/Documents/radeontop]$ clinfoNumber of platforms:                 1Platform Profile:                FULL_PROFILEPlatform Version:                OpenCL 1.2 AMD-APP (1214.3)Platform Name:               AMD Accelerated Parallel ProcessingPlatform Vendor:                 Advanced Micro Devices, Inc.Platform Extensions:                 cl_khr_icd cl_amd_event_callback      cl_amd_offline_devicesPlatform Name:               AMD Accelerated Parallel ProcessingNumber of devices:               1Device Type:                     CL_DEVICE_TYPE_CPUDevice ID:                   4098Board name:                  Max compute units:               8Max work items dimensions:           3Max work items[0]:               1024Max work items[1]:               1024Max work items[2]:               1024Max work group size:                 1024Preferred vector width char:             16Preferred vector width short:            8Preferred vector width int:          4Preferred vector width long:             2Preferred vector width float:            8Preferred vector width double:       4Native vector width char:            16Native vector width short:           8Native vector width int:             4Native vector width long:            2Native vector width float:           8Native vector width double:          4Max clock frequency:                 3633MhzAddress bits:                    64Max memory allocation:           4182872064Image support:               YesMax number of images read arguments:         128Max number of images write arguments:        8Max image 2D width:              8192Max image 2D height:                 8192Max image 3D width:              2048Max image 3D height:                 2048Max image 3D depth:              2048Max samplers within kernel:          16Max size of kernel argument:             4096Alignment (bits) of base address:        1024Minimum alignment (bytes) for any datatype:  128Single precision floating point capabilityDenorms:                     YesQuiet NaNs:                  YesRound to nearest even:           YesRound to zero:               YesRound to +ve and infinity:           YesIEEE754-2008 fused multiply-add:         YesCache type:                  Read/WriteCache line size:                 64Cache size:                  32768Global memory size:              16731488256Constant buffer size:                65536Max number of constant args:             8Local memory type:               GlobalLocal memory size:               32768Kernel Preferred work group size multiple:   1Error correction support:            0Unified memory for Host and Device:      1Profiling timer resolution:          1Device endianess:                LittleAvailable:                   YesCompiler available:              YesExecution capabilities:              Execute OpenCL kernels:          YesExecute native function:             YesQueue properties:                Out-of-Order:                NoProfiling :                  YesPlatform ID:                     0x00007f4ef63f0fc0Name:                        Intel(R) Core(TM) i7-4790 CPU @ 3.60GHzVendor:                  GenuineIntelDevice OpenCL C version:             OpenCL C 1.2 Driver version:              1214.3 (sse2,avx)Profile:                     FULL_PROFILEVersion:                     OpenCL 1.2 AMD-APP (1214.3)Extensions:                  cl_khr_fp64 cl_amd_fp64     cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_int64_base_atomics cl_khr_int64_extended_atomics cl_khr_3d_image_writes cl_khr_byte_addressable_store cl_khr_gl_sharing cl_ext_device_fission cl_amd_device_attribute_query cl_amd_vec3 cl_amd_printf cl_amd_media_ops cl_amd_media_ops2 cl_amd_popcnt What should I do in order to have access to the GPU?
