"Single Root I/O Virtualization (SR-IOV) technology has been steadily gaining momentum for high-performance interconnects such as InfiniBand. SR-IOV can deliver near native performance but lacks locality-aware communication support. This talk presents an efficient approach to build HPC clouds based on MVAPICH2 over OpenStack with SR-IOV. We discuss the high-performance design of virtual machine-aware MVAPICH2 library over OpenStack-based HPC Clouds with SR-IOV. A comprehensive performance evaluation with micro-benchmarks and HPC applications has been conducted on an experimental OpenStack-based HPC cloud and Amazon EC2. The evaluation results show that our design can deliver near bare-metal performance."
