SEAM uses spectral elements in the horizontal directions and sigma coordinates in the vertical. The model is both spectrally accurate, as demonstrated by a variety of test cases, and is well suited for modern distributed-shared memory computers, as demonstrated by the fact that we achieve 24 GFlops on a 240 processor HP Exemplar. More importantly, a 64 processor Exemplar can integrate a 20 level, 160 km resolution SEAM dynamical core at a rate of 3.6 wall clock hours per model year. SEAM is portable and is implemented in FORTRAN 77 with message passing calls.
