    Dragonfly topology was introduced by Kim et al. [1] aiming to decrease the cost and diameter of the network. The topology divides routers into groups connected by long links. Each group strives to implement high-radix virtual router, connected by a completely-connected topology. In this paper, we propose an extended Dragonfly+ network in which routers inside the group are connected in Clos-like to... View full abstract»

    Several of the most powerful supercomputers in the Top500 and the Graph500 lists continue choosing a torus topology to interconnect a large number of compute nodes. In some cases, a torus network with five or six dimensions is implemented, however, one notices that the costs of implementing an interconnection network increase with the node degree. In previous works we defined and characterized the... View full abstract»

  • New Link Arrangements for Dragonfly Networks

    Publication Year: 2017, Page(s):17 - 24
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (212 KB) | HTML iconHTML

    Dragonfly networks have been proposed to exploit high-radix routers and optical links for high performance computing (HPC) systems. Such networks divide the switches into groups, with a local link between each pair of switches in a group and a global link between each group. Which specific switch serves as the endpoint of each global link is determined by the network's global link arrangement. We ... View full abstract»

  • An Effective Queuing Scheme to Provide Slim Fly Topologies with HoL Blocking Reduction and Deadlock Freedom for Minimal-Path Routing

    Interconnection network performance becomes a key issue in HPC systems as their size grows. In order to maximize network performance with the minimum quantity of network resources, Slim Fly topology was proposed. It offers a high network bandwidth and assures a network diameter of two. However, in congestion situations where the head-of-line blocking effect arises, the Slim Fly performance may dro... View full abstract»

    Energy is emerging to become one of the most crucial factors in design decisions for future large scale computing systems. Especially Exascale-installations will have to operate within hard power and energy constraints. Besides economical reasons, power consumption is also limited by a limited power distribution, cooling capabilities, and minimization of carbon footprints. While other components, ...

  • Extending Commodity OpenFlow Switches for Large-Scale HPC Deployments

    Publication Year: 2017, Page(s):41 - 48
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1856 KB) | HTML iconHTML

    Commodity Ethernet networks are used in many HPC systems. Extensions based on OpenFlow have been proposed for large HPC deployments, considering scalability and power consumption concerns. Such designs employ low-diameter topologies to minimize power consumption, such as Flattened Butterflies or Dragonflies. However, these topologies require non-minimal adaptive routing to deal with varying traffi... View full abstract»

  • Isolating Jobs for Security on High-Performance Fabrics

    The various pieces of equipment in super-computers are shared between jobs, that belong to different users. This situation raises security concerns. Jobs must not be able to conduct denial of service attacks targeting other jobs (voluntarily or accidentally). Moreover, job isolation must be guaranteed: unauthorized communication between two different jobs should not be allowed. However, high-perfo... View full abstract»

    High-performance network packet processing benefits greatly from parallel-programming accelerators such as Graphics Processing Units (GPUs). Intel Xeon Phi, a relative newcomer in this market, is a distinguishing platform because its x86-compatible vectorized architecture offers additional optimization opportunities. Its software stack exposes low-level communication primitives, enabling fine-grai... View full abstract»
