Xiaoyi Lu from Ohio State University presented this talk at the Open Fabrics Workshop. “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 building HPC clouds based on MVAPICH2 and RDMA-Hadoop with SR-IOV.”
“We are pioneering the area of virtualized clusters, specifically with SR-IOV,” said Philip Papadopoulos, SDSC’s chief technical officer. “This will allow virtual sub-clusters to run applications over InfiniBand at near-native speeds – and that marks a huge step forward in HPC virtualization. In fact, a key part of this is virtualization for customized software stacks, which will lower the entry barrier for a wide range of researchers by letting them project an environment they already know onto Comet.”
The AMD graphics cards are uniquely equipped with AMD Multiuser GPU technology embedded into the GPU delivering consistent and predictable performance,” said Sean Burke, AMD corporate vice president and general manager, Professional Graphics. “When these AMD GPUs are appropriately configured to the needs of an organization, end users get the same access to the GPU no matter their workload. Each user is provided with the virtualized performance to design, create and execute their workflows without any one user tying up the entire GPU.”
In this talk, we will describe the challenges with live migration over SR-IOV enabled InfiniBand devices, and evaluate the first available prototype implementation of live migration over SR-IOV enabled InfiniBand devices.
