Chapter 4

Basic OpenCL Examples


In Chapter 2, we discussed the OpenCL specification and how it can be used to implement programs for heterogeneous platforms. Chapter 3 covered the architecture of some possible OpenCL targets. In this chapter, we discuss a few more complex examples, which build on the simple examples such as vector addition discussed in Chapter 2. We cover the implementation of both the host and the device code in a methodical manner.

The aim of this chapter is to give the reader more intuition of how OpenCL can be used to write data-parallel programs. The implementations in this chapter are complete OpenCL examples. However, they have not been tuned to take advantage of any particular device architecture. The aim ...
