The PGI Accelerator Programming Model on NVIDIA GPUs—Part 3 Porting WRF
Part 3 in the series looks at porting a large application to GPUs. This in-depth analysis looks at optimizing a key module in the Weather Research and Forecasting (WRF) application to run on GPUs. Through a combination of structural modifications and compiler feedback, the article demonstrates how to modify and then tune your application for better performance. The article concludes with a comparison of the relative performance of the port done with the PGI Accelerator compilers and a version ported to CUDA C.
