Chapter 3. Software Architecture

This chapter provides an overview of the CUDA software architecture. Chapter 2 gave an overview of the hardware platform and how it interacts with CUDA, and we’ll start this chapter with a description of the software platforms and operating environments supported by CUDA. Next, each software abstraction in CUDA is briefly described, from devices and contexts to modules and kernels to memory. This section may refer back to Chapter 2 when describing how certain software abstractions are supported by the hardware. Finally, we spend some time contrasting the CUDA runtime and driver API and examining how CUDA source code is translated into microcode that operates on the GPU. Please remember that this chapter is just ...
