AMD's GPU_MAX_ALLOC_PERCENT equivalent in Intel OpenCL SDK?

Hi,

I just installed the opencl-1.2-3.0.67279 XE version and it seems that the largest object I can allocate is 4GB. However, my Core i7 3770K machine has 16GB.

CL_DEVICE_GLOBAL_MEM_SIZE:    16780570624
CL_DEVICE_MAX_MEM_ALLOC_SIZE:    4195142656

I know AMD has this environment variable to use almost all  of the GPU global memory available in a single allocation

export GPU_MAX_ALLOC_PERCENT=100

Is there something similar for the Intel OpenCL implementation?

Thanks
