Slim Fly: A Cost Effective Low-Diameter Network Topology

  title={Slim Fly: A Cost Effective Low-Diameter Network Topology},
  author={Maciej Besta and Torsten Hoefler},
  journal={SC14: International Conference for High Performance Computing, Networking, Storage and Analysis},
We introduce a high-performance cost-effective network topology called Slim Fly that approaches the theoretically optimal network diameter. Slim Fly is based on graphs that approximate the solution to the degree-diameter problem. We analyze Slim Fly and compare it to both traditional and state-of-the-art networks. Our analysis shows that Slim Fly has significant advantages over other topologies in latency, bandwidth, resiliency, cost, and power consumption. Finally, we propose deadlock-free… CONTINUE READING
