Read and print data from local memory .

You CANNOT read from or write to local memory buffers from the host. You can only communicate between host and device using global memory. You have to write your data to global memory in the host, then copy it to local memory in the kernel, then write back to global memory in the kernel, then read it from global memory in the host. Local memory is designed to be used for keeping temporary data on the device, and is not directly accessible from the host.
