Abstract(in English) The number of computing nodes increases for both on-chip multi-core systems and supercomputers. Therefore, the network latency among the nodes is a critical issue for parallel applications. Recently researchers have shown that randomly connected networks can reduce the latency for both on-chip and off-chip systems. However, unlike regular networks, conventional routing methods induce deadlocks due to loops of channel dependencies on these networks. Recently proposed theorem that generalizes the turn model can achieve almost minimal and fully adaptive deadlock-free routing. However, it cannot be applied to irregular networks that contain diagonal links. In this work, we advance the theorem to apply it to arbitrary network topologies. We also provide a practical implementation based on the theorem. Experimental results show that it can improve network throughput by up to 138 % and can reduce the network latency by up to 2.9 % compared to conventional routing methods.
