Parallel algorithm for executing fuzzy Kohonen clustering network  (FKCN) for
image segmentation on distributed computer   system with torus topology is
presented. Two approaches for parallelizing computations of global values are
investigated  a spanning tree approach and multiplication of computations (a
butterfly approach). The impossibility of message congestions on torus links
is proved for the hypercube-onto-torus  XOR-embedding. Expressions for the
parallel FKCN performance analysis are given. For distributed image processing
systems having two- and three-measured torus topologies  the analysis shows
good estimation of the parallel  FKCN implementation.
