Square grid topology

The self-assembly of [Cu (dien)(H20)2] + and [W (CN ] from an aqueous solution affords two-dimensional layers of stoichiometry [Cu"(dien)]2[W (CN)8] 4H20 . The crystal structure of this compound comprises tightly folded layers of a square grid-like topology (Figure 36). 

Since MIMD transputers execute different instructions and work on different data, the interconnection between them must be carefully planned. It is unthinkable to connect each transputer to all other transputers. The number of connections rises as the square of the number of units. From a number of possibilities, most customarily used topologies are binary trees, two-dimensional grids and hypercubes (Figure 7.15). Sophisticated MIMD implementations allow for user-configuration of topologies to suit particular needs.
