In the previous three posts of this CUDA Fortran series we laid the groundwork for the major thrust of the series: how to optimize CUDA Fortran code. In this and the following post we begin our discussion of code optimization with how to efficiently transfer data between the host and device. The peak bandwidth between the device memory and the GPU is much higher (144 GB/s on the NVIDIA Tesla C2050��
