ABSTRACT Torus networks are an attractive topology in supercomputing, balancing the tradeoff between network diameter and hardware costs. The nodes in a torus network are connected in a k-dimensional wrap-around mesh where each node has 2k neighbors.

What is Torus in CSE?

A Torus interconnect is a network topology for connecting processing nodes in a parallel computer system. A number of supercomputers on the TOP500 list use 3D Torus networks.

What is the diameter of a 3D Torus network of P processors?

If there is a processor at each nodes and leaves of the tree then the diameter is D = 2 log2( p-12) for p processors.
