A look at GPU memory transfer
One of the trickier things in programming with multiple devices is managing the transfer of data between devices. This applies whether you’re programming a cluster or a machine with a CPU and GPU. Transferring data takes time and the programmer must be careful that the transfer time doesn’t overpower any performance gains from parallelizing your algorithm. When talking about transfer time, we usually think of it as having two components: the time due to latency and the time due to bandwidth. The total time to transfer the data is then,
