Developing Geophysical Fluid Dynamics Models on Emerging Architectures
In this talk, I will describe our approach to developing computational fluid dynamics (CFD) models that will run on emerging computer architectures. I will review our past experience with writing a single-source code-base for use with various types of architectures and whether this approach is sustainable. Questions that arise are: which programming language is best suited for this task and how performant can these models be? Rather than talking in generalities, I will discuss results related to two modeling efforts underway at the Naval Postgraduate School. The first is the NUMA model which is a mature mostly Fortran-based atmospheric model and the second is the CLIMA model which is a new modeling framework written in Julia with components for both the atmosphere and ocean (with more components to be added in the future).


Frank Giraldo is a professor of Applied Mathematics at the Naval Postgraduate School and director of the Center for Computational Mathematics. Frank serves on various national boards such as the National Earth Systems Prediction Capability (ESPC) High-Performance Computing Working Group and the National Unified Operational Prediction Capability (NUOPC) group. In addition, Frank also serves on various panels such as the DOE’s E3SM review panel (past 5 years), and the DOE’s INCITE panel in Earth Sciences (for the past 4 years, having chaired the panel for the past two years). Frank also served on the Scientific Advisory Committee for the Korea Institute of Atmospheric Prediction System when it was first founded in 2011.
