The purpose of this chapter is to learn how to express parallelism for a 3D finite difference code using OpenACC directives. It is common for scientific and engineering communities to use finite difference methods to solve partial differential equations.
After completing this chapter, you will have a basic understanding of:
•A finite difference code
•How to convert OpenMP code to OpenACC
•Practical techniques to profile and analyze performance behavior of finite difference codes
•How to use Unified Memory with OpenACC
•Testing portability targets including multicore systems
