Chapter 1. First Programs and How to Think in CUDA
The purpose of this chapter is to introduce the reader to CUDA (the parallel computing architecture developed by NVIDIA) and differentiate CUDA from programming conventional single and multicore processors. Example programs and instructions will show the reader how to compile and run programs as well as how to adapt them to their own purposes. The CUDA Thrust and runtime APIs (Application Programming Interface) will be used and discussed. Three rules of GPGPU programming will be introduced as well as Amdahl's law, Big-O notation, and the distinction between data-parallel and task-parallel programming. Some basic GPU debugging tools will be introduced, but for the most part NVIDIA has made debugging ...
