Abstract
The High-Order Method Modeling Environment (HOMME) is a framework to investigate using high-order element-based methods to build conservative and accurate atmospheric general circulation models. Currently, HOMME employs the discontinuous Galerkin and spectral element methods on a cubed-sphere tiled with quadrilateral elements to solve the primitive equations, and has been shown to scale to (10K) processors of a Cray XT 3/4 and (32K) processors of an IBM Blue Gene/L. Here we briefly describe the development of a baroclinic model using the discontinuous Galerkin option in the HOMME framework, present idealized test case results, and provide preliminary performance data.Keywords
