10 GPU programming model
This chapter covers
- Developing a general GPU programming model
- Understanding how it maps to different vendors’ hardware
- Learning what details of the programming model influence performance
- Mapping the programming model to different GPU programming languages
In this chapter, we will develop an abstract model of how work is performed on GPUs. This programming model fits a variety of GPU devices from different vendors and across the models from each vendor. It is also a simpler model than what occurs on the real hardware, capturing just the essential aspects required to develop an application. Fortunately, various GPUs have a lot of similarities in structure. This is a natural result of the demands of high-performance ...
