高性价比的PC机群已经成为高性能计算的典型平台之一。为了降低成本，千兆以太网通常用于内部通信网络。然而，以太网的可靠性是有限的，由于硬件故障和网络交换机的尝试性错误。为了解决这个问题，我们提出了一种基于多链路以太网的互连网络系统RI 2N。在本文中，我们开发了一个使用UDP/IP的RI 2N的用户级实现，称为RI 2N/UDP。在对这一新系统进行性能和容错评估时发现，双链路千兆以太网的带宽为246 MB/s，系统在网络链路故障期间可以保持活动状态，从而提供高系统可靠性。
PC-clusters with high performance/cost ratio have been one of the typical platforms for high performance computing. To lower costs, Gigabit Ethernet is often used for intercommunication networks. However, the reliability of Ethernet is limited due to hardware failures and tentative errors in the network switches. To solve this problem, we propose an interconnection network system based on multi-link Ethernet named RI2N. In this paper, we developed a user level implementation of RI2N using UDP/IP that is called RI2N/UDP. When this new system was evaluated for performance and fault tolerance, the bandwidth on a 2-link Gigabit Ethernet was 246 MB/s, and the system could remain active during network link failure to provide high system reliability.
