GPU : no atomic ?

Hi,

I have an Intel i7 4702MQ processor and need to use the "atomic" methods of this GPU (not CPU).

But when I use cl_khr_global_int32_base_atomics, I got an error. It is not yet supported ?

You can check the device caps using gpucapsviewer or query programmatically. But the above extension should be supported on HD 4600. What error were you getting? Can I reproduce that with the kernel you sent me (privately)?

Thanks,
Raghu
