A printed circuit board with a two-dimensional torus topology provided herein. The printed circuit board includes an array of board connectors, an input port and an output port, and a set of interconnections. Each board connector of the array of board connectors is formed to receive an electronic connector. The input port and the output port are formed on each board connector to provide an identical trace routing direction. The set of interconnections are formed to connect each board connector to another board connector. The signal path between each of the interconnections has a length less than a distance between a first board connector and a last board connector in the array of board connectors.
