GPU : no atomic ?

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 ?

For more complete information about compiler optimizations, see our Optimization Notice.

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
