LinuxCon + ContainerCon North America 2016

Low latency, high bandwidth communication is critical for HPC workloads. In this presentation we describe the architecture and performance characteristics of Linux guest RDMA with Hyper-V as the host. The primary deployment target for this functionality is public Cloud environments where tenant isolation is critical. We have come up with an interesting architecture where the Control plane is over a software mediated path (to ensure security) while the Data plane completely by-passes both host and the guest kernels. The result is a near-native performance profile while ensuring security.
