    GPU Direct equivalent in AMD OpenCL




                As in NVIDIA CUDA based GPU direct in which we can communicate with GPU and CPU or GPU and GPU with less latency , do we have anything equivalent to this with AMD OpenCL ? According to my understanding, Zero copy( with CL_MEM_ALLOC_HOST_PTR) in clCreateBuffer ,is between CPU and GPU . Can anyone tell me how to communicate between two GPUs without host interference in OPENCL ?
