MASSIVE PARALLELIZATION OF NMCS SPECTRAL MODEL

This paper briefly describes the formulation of NMC's Spectral Model a nd the numerical methods used in its implementation. The various segme nts of the numerical algorithm are analyzed for suitability to a massi vely parallel architecture and a computer algorithm is designed for ex ecution on a CM-200 computer. Special emphasis is placed on the produc tion of a fast Legendre Transform and the minimization of interprocess or communication. Performance and scalability issues are presented.
