We first demonstrate the parallel performance of the dynamical core of a spectral element atmospheric model. The model uses continuous Galerkin spectral elements to discretize the surface of the Earth, coupled with finite differences in the radial direction. Results are presented from two distributed memory, mesh interconnect supercom-puters (ASCI Red and(More)
1 Usefulness of calculating Fourier series in the SEM In this note is presented a method, given nodal values on multidimensional nonconforming spectral elements, for calculating global Fourier-series coefficients. This method is " exact " in that given the approximation inherent in the spectral-element method (SEM), no further approximation is introduced(More)
