The torus has been a popular topology for multicomputers due to its ease of implementation. Existing networks, such as the tents, are graph topologies, where a channel connects exactly two nodes. This paper argues that hypergraph topologies, where a channel connects any number of nodes, are potential candidates for future high-performance multicomputer networks. The paper assesses the support of a multi-dimensional hypergraph, referred to as the Distributed Crossbar Switch Hypermesh (DCSH), and the torus for communication locality. The results show that DCSH is a more general structure as it supports more efficiently a wide range of traffic patterns
