通常接受不规则拓扑的系统区域网络(SAN)已被用来连接PC/WS集群或高性能存储系统中的节点。人们已经提出了许多无死锁的SAN路由，并对其进行了广泛的仿真评估。然而，这些模拟结果可能与真实PC集群的结果不同，因为模拟中使用的主机、网络接口和交换机被简化以获得足够的模拟速度。在本文中，我们在一个高性能的PC集群RHiNET-2上实现了无死锁的路由，并对其性能进行了评估。执行结果表明，DL路由和结构化信道池实现了屏障同步的总带宽和执行时间几乎相同。与简单的Up*/Down*路由相比，它们提高了总带宽的51%和屏障同步执行时间的29%。
System area networks (SANs), which usually accept irregular topologies, have been used to connect nodes in PC/WS clusters or high-performance storage systems. A lot of deadlock-free routings for SANs have been proposed, and their evaluation on simulations have been widely done. However, these simulation results may differ from that of real PC clusters, since hosts, network interfaces and switches used in the simulation are simplified for achieving enough simulation speed. In this paper, we implement deadlock-free routings on a high-performance PC cluster called RHiNET-2, and evaluate their performance. Execution results show that the DL routing and the structured channel pools achieve almost the same total bandwidth and execution time of the barrier synchronization. Compared with the simple Up*/Down* routing, they improve 51% of total bandwidth and 29% improvement on execution time of the barrier synchronization.
