WRF Goddard Microphysics Scheme Optimization

Jarno Mielikainen; Bormin Huang; Allen H.-L. Huang    University of Wisconsin-Madison, USA

Abstract

This chapter examines the optimization of numerical weather prediction through optimizations that include reducing the memory bound nature of the code. Code restructuring for better vectorization is also shown to be essential for such a legacy code. The code that is optimized is the weather research and forecasting model, an open source numerical weather prediction model.
