Interconnection network plays an important role in massively parallel systems. As a high performance switched network standard, Infiniband is widely used in MPP systems. Compared to fat-tree topology which is commonly used in Infiniband networks, mesh/torus topology can achieve better performance and scalability. This paper proposes an Infiniband-based multi-path mesh/torus interconnection network which provides higher bandwidth than traditional networks by using multiple links between switches. The corresponding routing scheme for the improved network is also proposed. The scheme is evaluated by simulation, and the results show that our proposed routing scheme achieves better performance and scalability than other routing schemes.
