Abstract
We consider the implications of Amdahl's Law for a heterogeneous syste m of computers each of which is a homogeneous parallel processor. We i ntroduce a parallelism profile function to describe the level of paral lelism achieved in different fragments of the computation and demonstr ate that, for some choices of this function, the performance of a hete rogeneous system significantly exceeds that of each of the component h omogeneous systems.
