Resumo


We describe the first parallel version or CPTEC's General Circulation Model, targeting a 4 processor, shared memory NEC SX4. This paper emphasizes techniques to parallelize vintage production code, keeping results reproducible. Measured speed-ups compare favorably with Amdahl's Law predicted values.
