    Designing High Performance, Scalable and Fault-Resilient MPI Library for Modern Clusters
    Update time: 2010-10-22
    Text Size: A A A

    Time: 9:30am-11:00am, October 26th,2010
    Place: Room 446, 4th Floor, ICT, CAS
    Speaker:Prof. DK Panda, IEEE Fellow, Ohio State University

    This presentation will start with an overview of the emerging networking technologies and protocols (InfiniBand, Ethernet/iWARP and RDMA over Converged Enhanced Ethernet) for designing modern clusters. An overview of high performance, scalable and fault-tolerant/resilient MPI library while exploiting these emerging networking technologies/protocols and their features will be presented. Advanced designs and features of the MVAPICH/MVAPICH2 library including scalable inter-node communication with different transport protocols, kernel-based zero-copy intra-node communication, one-sided communication, multi-core-aware hierarchical collectives, etc. will be presented. Applications-level studies using MVAPICH/MVAPICH2 library will be highlighted. Finally, we will critically examine some of the needs of designing MPI libraries for next generation exascale systems.

    Dr. Panda is an IEEE Fellow and a member of ACM. His research interests include parallel computer architecture, high performance computing and networking, communication protocols, files systems, data-centers, programming models, fault-tolerance and exascale computing. He has published over 275 papers in major journals and international conferences related to these research areas. Dr. Panda and his research group members have been doing extensive research on modern networking technologies. More details about him are available at http://www.cse.ohio-state.edu/~panda.
