Slim Fly: A Cost Effective Low-Diameter Network Topology
(presented in New Orleans, LA, USA, Nov. 2014, Proceedings of the International Conference on High Performance Computing, Networking, Storage and Analysis (SC14) ) SC14 Best Student Paper (1/82)
Abstract
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 routing schemes and physical layouts for large
computing centers as well as a detailed cost and power model. Slim
Fly enables constructing cost effective and highly resilient
datacenter and HPC networks that offer low latency and high
bandwidth under different HPC workloads such as stencil or graph
computations.
