In modern computing architectures, graph theory is the soul of the play due to the rising core counts. It is indispensable to keep finding a better way to connect the cores. A novel chordal-ring interconnect topology system, Equality, is revisited in this paper to compare with a few previous works. This paper details the procedures for constructing the Equality interconnects, its special routing procedures, the strategies for selecting a configuration, and evaluating its performance using the open-source cycle-accurate BookSim package. Four scenarios representing small- to large-scale computing facilities are presented to assess the network performance. This work shows that in 16,384-endpoint systems, the Equality network turns out to be the most efficient system. The results also show the steady scalability of Equality networks extending to 48–320K, and a million endpoints. Equality networks are adjustable to fit with commodity hardware and resilient under ten common traffic models. It is suggested that Equality network topology can be used in constructing efficient multi-exaflops supercomputers and data centers.
