    GPU Direct equivalent in AMD OpenCL

    anu10111988

      Hi,

       

                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 ?

       

       

      Thanks
