Heterogeneous Processing: a Strategy for Augmenting Moore's Law
Although many exciting avenues of exploration are underway today in the field of heterogeneous computing, we are not yet at the point where this model will take over as the dominant HPC system architecture. The barriers that remain (primarily, difficulties programming for and porting existing code to heterogeneous systems) are significant. However, Cray and others in the HPC community are already making strides in these areas.
As with any new technology, widespread adoption of heterogeneous systems will depend on an analysis of the gains that can be achieved versus the effort required to realize them. In the long term, we believe that the performance advantages offered by heterogeneous architectures for some applications will be too compelling to ignore.
