The Tofu interconnect uses a 6D mesh/torus topology in which each cubic fragment of the network has the embeddability of a 3D torus graph, allowing users to run multiple topology-aware applications. This article describes the Tofu interconnect architecture, the Tofu network router, the Tofu network interface, and the Tofu barrier interface, and presents preliminary evaluation results.
