摘要：
Communication is increasingly more costly than computation, but little work has been done on characterising the intrinsic communication behaviour of algorithms. We show that the dynamic data dependency graphs for a wide number of benchmarks exhibit multi-scale fractal communication. This has important implications for the locality of NoC communication in a CMP as well as for temporal locality. Benchmarks that do not exhibit fractal scaling or that have high fractal dimensionality may have poor communication scalability on a CMP.
