Abstract :
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.
