5.7 Parallel implementation

As mentioned in this paper, the most computational intensive task is the dimensionality reduction made by the self-organizing maps. Fortunately, a decomposition into small independent tasks is possible and a parallel implementation can easily be developed. The design of a possible architecture for SIMD (Single Instruction stream, Multiple Data stream) computers is explained in [Ultsch et al., 1992]. Some other parallel-computer implementations are referenced in [Kohonen, 1995].
