Automated Design of Torus Networks (1301.6180v1)

Abstract: This paper presents an algorithm to automatically design networks with torus topologies, such as ones widely used in large-scale supercomputers. The characteristic feature of our approach is that real life equipment prices and values of technical characteristics are used. As a result, we also have the opportunity to compare costs of torus and fat-tree networks. The algorithm is useful as a part of a bigger design procedure that selects optimal hardware of cluster supercomputer as a whole.
