Design of an Enhanced Global Spectral Model

Abstract

The objective of this study is the development of a vectorized, multiprocessing global spectral model (GSM) with enhanced physical parameterizations. The starting point for this work is the current Geophysics Laboratory (GL) GSM. Described is the multitasking and vectorization design for the GSM. One proposes to implement the latitude tasking scheme for multiprocessing the loop over latitude in the calculation of spectral tendencies and adjusted model variables. The general truncation version of the hydrodynamics code will be used. Wavenumber calculations will be multiprocessed and vectorized over wavenumber. All gridpoint calculations will be vectorized over longitude. The physics packages will be modified to bring them into close compliance with the plug compatibility rules.
