NK-GPGPU A GPGPU model for nested kernels

摘要

More and more scientific problems are now using GPGPU to solve. However, the existing GPGPU did not give a good solution for the problems such as recursive calls and multiple calls problems. Our proposed NKGPGPU model is a descriptive model that solves the key issues of the NK-GPGPU, including hardware architecture, task organization, task execution, and task scheduling. We also prove the validity of our model by optimizing an existing GPGPU performance prediction model.
