分层环面网络（HTN）是多个基本模块的2D环面网络，其中基本模块是分层互连以用于更高级别网络的3D环面网络。HTN的动态通信性能的维序路由下常见的交通模式进行了评估，并已被证明是好的。然而，HTN的动态通信性能下不利的交通模式尚未进行评估。在本文中，我们评估了HTN的动态通信性能，使用无死锁的维序路由与3个虚拟通道，并将其与H3D网格，网格，环面网络。它示出，即使在不利的流量模式下，HTN产生高吞吐量和非常低的零负载延迟，提供更好的动态通信性能比H3D网格，网格和环面网络。
A Hierarchical Torus Network (HTN) is a 2D-torus network of multiple basic modules, in which the basic modules are 3D-torus networks that are hierarchically interconnected for higher level networks. The dynamic communication performance of the HTN using the dimension-order routing under common traffic patterns have been evaluated, and have been shown to be good. However, dynamic communication performance of HTN under adverse traffic patterns has not been evaluated yet. In this paper, we evaluate the dynamic communication performance of HTN using a deadlock-free dimension order routing with 3 virtual channels, and compare it with H3D-mesh, mesh, and torus networks. It is shown that even under adverse traffic patterns, the HTN yields high throughput and very low zero load latency, which provide better dynamic communication performance than H3D-mesh, mesh, and torus networks.
