CL_DEVICE_ADDRESS_BITS returns 32 for a 6GB Radeon 7970
I have a Radeon 7970 and need more than 4GB. Currently, querying the device for adddress bits returns 32. I assume this is why I can't fully use my 6GB . Is it possible to use more than 4GB like CUDA?
Or does the AMD OpenCL driver only support 32bit addressing?
