An Update on the Parallelization of the FV3 Model for cpu , gpu , and MIC Processors

NOAA's Earth System Research Laboratory (ESRL) has been working on the parallelization of the FV3 dynamical core toward fine-grain GPU and MIC processors. Initial work focused on modifying the code to expose more loop level parallelism needed to run efficiently on GPU processors containing over 3000 processing cores. Code changes have been quite...

Parallelization and Performance of the NIM Weather Model on CPU, GPU, and MIC Processors

The design and performance of the Non-Hydrostatic Icosahedral Model (NIM) global weather prediction model is described. NIM is a dynamical core designed to run on central processing unit (CPU), graphics processing unit (GPU), and Many Integrated Core (MIC) processors. It demonstrates efficient parallel performance and scalability to tens of thou...

A Vertically Flow-Following Icosahedral Grid Model for Medium-Range and Seasonal Prediction. Part I: Model Description

A hydrostatic global weather prediction model based on an icosahedral horizontal grid and a hybrid terrain-following/isentropic vertical coordinate is described. The model is an extension to three spatial dimensions of a previously developed, icosahedral, shallow-water model featuring user-selectable horizontal resolution and employing indirect ...
