Motivation

Sequential codes are too slow and expensive. For the simulation to have a significant impact on the design process, the designer should have the flexibility of experimenting with different blade geometries and have results turn-around in a matter of days rather than weeks. Simulation of the rotor-stator interaction for a typical geometry, using a sequential code may run for a month (or more) on a Cray-C90. Parallelization reduces the turnaround by an order of magnitude.
