Abstract: We describe the design of a parallel global atmospheric circulation model, PCCM2. This parallel model is functionally equivalent to the National Center for Atmospheric Research's Community Climate Model, CCM2, but is structured to exploit distributed memory multicomputers. PCCM2 incorporates parallel spectral transform, semi-Lagrangian transport, and load balancing algorithms. We present detailed performance results on the IBM SP2 and Intel Paragon. These results provide insights into the... (Update)

.... many algorithms proposed and examined on various computers so far about the parallelization of the spectral transform method [12, 13, 14]. Here the outline of the Legendre transform (LT) that makes up the core part of the spectral transform will be given by following Foster...
.... wandering around the stable regime C (shifting from C1 to C2) Another example is the spectral transforms used in many atmospheric models [8, 13], where global summations are very sensitive to the summation order. In this case, there is no self correcting mechanism as in the...
