Topology Architecture and Routing Algorithms of Octagon-Connected Torus Interconnection Network
Abstract: Two important issues
in the design of interconnection networks for massively parallel computers are
scalability and small diameter. A new interconnection network topology, called
octagon-connected torus (OCT), is proposed. The OCT network combines the small
diameter of octagon topology and the scalability of torus topology. The OCT
network has better properties, such as small diameter, regular, symmetry and
the scalability. The nodes of the OCT network adopt the Johnson coding scheme
which can make routing algorithms simple and efficient. Both unicasting and
broadcasting routing algorithms are designed for the OCT network, and it is
based on the Johnson coding scheme. A detailed analysis shows that the OCT
network is a better interconnection network in the properties of topology and
the performance of communication.
