Abstract :
We discuss the parallel implementation of a global spectral atmospheric general circulation model on a message passing platform. We also discuss strategies that need to be employed to improve performance on parallel machines which will have multiprocessor nodes sharing an intra-node memory space. A brief discussion of the cause of load imbalances and simple methods to reduce the same are also presented
