7 OpenMP that performs
This chapter covers
- Planning and designing a correct and performant OpenMP program
- Writing loop-level OpenMP for modest parallelism
- Detecting correctness problems and improving robustness
- Fixing performance issues with OpenMP
- Writing scalable OpenMP for high performance
As many-core architectures grow in size and popularity, the details of thread-level parallelism become a critical factor in software performance. In this chapter, we first introduce the basics of Open Multi-Processing (OpenMP), a shared memory programming standard, and why it’s important to have a fundamental understanding of how OpenMP functions. We will look at sample problems ranging in difficulty from a simple common “Hello World” example to a complex ...
