Sharing High-Performance Interconnects Across Multiple Virtual Machines

Mohan Potheri from VMware gave this talk at the Stanford HPC Conference. “Virtualized devices offer maximum flexibility. This session introduces SR-IOV, explains how it is enabled in VMware vSphere, and provides details of specific use cases that important for machine learning and high-performance computing. It includes performance comparisons that demonstrate the benefits of SR-IOV and information on how to configure and tune these configurations.”

Building Efficient HPC Clouds with MCAPICH2 and RDMA-Hadoop over SR-IOV IB Clusters

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.”

AMD Demos World’s First Hardware-Based Virtualized GPU Solution

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.”

Virtual Machine Migration with SR-IOV Over InfiniBand

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.
