Feasible models of computation: three- dimensionality and energy consumption

Sanders, Peter; Vollmar, Roland; Worsch, Thomas

Abstract:

Using cellular automata as models of parallel machines we investigate the
relation between (r-1)- and r-dimensional machines and constraints for the
energy consumption of r-dimensional machines which are motivated by
fundamental physical limitations for the case r=3. Depending on the
operations which must be considered to dissipate energy (state changes,
communication over unit-length wires, ...), some relations between the
relative performance of 2-dimensional and 3-dimensional machines are
derived. In the light of these results it seems imperative that for
feasible models of computation energy consumption has to be considered as
an additional complexity measure.
