i installed amd app sdk , here problem. opencl samples not detect gpu. helloworld give me this:
[thomas@clemence:/opt/amdapp/samples/opencl/bin/x86_64]$ ./helloworld no gpu device available. choose cpu default device. input string: gdkknvnqkc output string: helloworld passed! and here clinfo output

here graphics card:
[thomas@elsa:~]$ lspci | grep -i --color 'vga' 00:02.0 vga compatible controller: intel corporation xeon e3-1200 v3/4th gen core processor integrated graphics controller (rev 06) 01:00.0 vga compatible controller: advanced micro devices, inc. [amd/ati] oland xt [radeon hd 8670 / r7 250/350]
not gpu´s in market support opencl. check out if gpu support opencl? gpu drivers date?
when heppen me , root cause change graphics card, without update driver , deafult windows driver used.
