The methodology is comprised of two major phases:

  1. Architecting the application
  2. Developing the C/C++ kernels

In the first phase, the developer makes key decisions about the application architecture by determining which software functions should be mapped to device kernels, how much parallelism is needed, and how it should be delivered.

In the second phase, the developer implements the kernels. This primarily involves structuring source code and applying the desired compiler pragma to create the desired kernel architecture and meet the performance target.

Figure 1. Methodology Overview

Performance optimization is an iterative process. The initial version of an accelerated application will likely not produce the best possible results. The methodology described in this guide is a process involving constant performance analysis and repeated changes to all aspects of the implementation.
