Abstract
With the increasing demand of high-performance computing, network topology, as a key component of connecting computing nodes, has a significant impact on system performance. This study aims to explore efficient network topologies suitable for high-performance computers and propose a hybrid topological model based on adaptive routing algorithm by comparing conventional and novel topologies. The model combines the advantages of 2 D mesh and 3 D torus to improve bandwidth utilization while ensuring low latency. The study combines theoretical modeling with simulation experiments to construct multiple representative test scenarios to evaluate the network performance under different load conditions. The experimental results show that the proposed hybrid topology exhibits a significant advantage in communication-intensive tasks, with an average delay reduction of about 30% and a throughput improvement by more than 25%.
