A Case for RDMA in Clouds: Turning Supercomputer Networking into Commodity

Free registration required

Executive Summary

Modern cloud computing infrastructures are steadily pushing the performance of their network stacks. At the hardware-level, already some cloud providers have upgraded parts of their network to 10GbE. At the same time there is a continuous effort within the cloud community to improve the network performance inside the virtualization layers. The low-latency/high-throughput properties of those network interfaces are not only opening the cloud for HPC applications, they will also be well received by traditional large scale web applications or data processing frameworks. However, as commodity networks get faster the burden on the end hosts increases.
