Description: The emerging InfiniBand architecture  is providing a new way to design next generation high performance clusters. In addition to the higher network speed, this architecture provides several new mechanisms (RDMA, multicast, atomic, and service levels) to build high performance and efficient communication subsystems for clusters. At OSU, a high performance MPI implementation (MVAPICH) [2,3] with a focus toward point-to-point communication has been recently designed and developed to take advantage of InfiniBand for next generation clusters.
