Abstract

Progress in the development of the PetaScale implementation of the anelastic EULAG model combined with the warm-rain bulk and bin microphysics schemes, as well its application to multiscale cloud modeling, are presented. A new three-dimensional (3D) model domain decomposition is implemented to increase model performance and scalability. We investigate performance of the code on IBM BlueGene/L and Cray XT4/XE6 architectures. The scalability results show significant improvement of the new domain decomposition over the previous 2D decomposition used as the standard in many geophysical fluid flow models.
