Low Latency, High Throughput, RDMA and the Cloud in Between
SESSION: Low Latency, High Throughput, RDMA and the Cloud in Between
EVENT TYPE: Birds of a Feather
TIME: 12:15PM - 1:15PM
SESSION LEADER(S):Gilad Shainer, Jeff Layton
ABSTRACT: Latency, Throughput, RDMA and offloading are among the most critical capabilities the influence on application performance in high performance and beyond. For years, Ethernet lagged behind other networking solution in providing real low latency solution, and while many organizations claim to achieve low latency Ethernet, in most cases it is still an order of magnitude higher than what is needed. For enabling the true low latency Ethernet, new proposals now raise the idea of using different transport protocols on top of Ethernet, as such transports were proven to provide low latency and other important networking elements. InfiniBand has already provided sub-micro second latencies and excels in throughput, and now it is demonstrating new capabilities that have been the desire of leading edge research systems and positions itself as the leading solution for the most scalable systems in the world. In between we are witnessing the formulation of the fourth mode of science - Science Discovery, in which HPC clouds will be required to handle the data flood generated by computation science simulations. The Session will review the latest development for RDMA over Ethernet (aka RoCE) and the new InfiniBand FDR and EDR roadmap with various examples of usage cases and simulations results, and a peak into the future requirements that will be needed for the fourth mode of science.
