FT Demonstrates High Performance InfiniBand on Wide-Area Networks

FT group members Weikuan Yu and Jeffrey Vetter, along with Nageswara Rao (also of Computer Science and Mathematics at ORNL), will be presenting their recent analysis results on high performance InfiniBand on wide-area networks in the 2008 IEEE Network, Architecture and Storage conference in Chongqing, China. Using the OC192 SONET connections from UltraScience Net, they have demonstrated that a network-level bandwidth of 7.4Gbps and an MPI-level bandwidth of 758MB/sec are achievable across two InfiniBand clusters that are 8600 miles apart. Part of results will also be presented in the OpenFabrics Conference in Sonoma, California.   For more information see the paper.
