19 Spatial Computational Domain Sufficiently coarse to ensure that the derivation and decomposition of the spatial computational domain is computationally inexpensive Sufficiently fine to allow domain decomposition to produce a large number of sub-domains that are executed concurrently to improve computational performance 19 Wang, S., and Armstrong, M.

21 Computational Intensity Question What is the nature of computational intensity of geographic analysis? o Why spatial is special? Comparable to o “What is the nature of computational complexity of an algorithm?” 21
