Much of the promise of GPU computing lies in exploiting the massively parallel structure of many problems. In this vein, this chapter examines how to execute parallel code on the GPU using CUDA C.

This chapter is from the book 

In the previous chapter, we saw how simple it can be to write code that executes on the GPU. We have even gone so far as to learn how to add two numbers together, albeit just the numbers 2 and 7. Admittedly, that example was not immensely impressive, nor was it incredibly interesting. But we hope you are convinced that it is easy to get started with CUDA C and you're excited to learn more. Much of the promise of GPU computing lies in exploiting the massively parallel structure of many problems. In this vein, we intend to spend this chapter examining how to execute parallel code on the GPU using CUDA C.

4.1 Chapter Objectives

Through the course of this chapter, you will accomplish the following:

You will learn one of the fundamental ways CUDA exposes its parallelism.
You will write your first parallel code with CUDA C.
