Chapter 9

Accelerating 3D wave equations using OpenACC

Ty McKercher     NVIDIA Corporation, Houston, TX, United States


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
