Kronecker Products, Polarity Quotients and Large Graph Constructions

Kelly Isham, Kartik Lakhotia, Laura Monroe +1

In this paper, we establish a structural compatibility between the Kronecker product of bipartite graphs that admit polarity and their polarity quotient, and provide a sharp upper…

PCCL: Process Group-Aware Scalable and Generic Collective Algorithm Synthesizer

William Won, Kartik Lakhotia, Madhu Kumar +2

Distributed machine learning has become increasingly important due to the massive scale of large-scale generative models. Both model parameters and data are distributed across many…

Edge-Disjoint Spanning Trees on Star-Product Networks

Kelly Isham, Laura Monroe, Kartik Lakhotia +3

A star-product operation may be used to create large graphs from smaller factor graphs. Network topologies based on star-products demonstrate several advantages including low-diame…

A High-Performance Design, Implementation, Deployment, and Evaluation of The Slim Fly Network

Nils Blach, Maciej Besta, Daniele De Sensi +10

Novel low-diameter network topologies such as Slim Fly (SF) offer significant cost and power advantages over the established Fat Tree, Clos, or Dragonfly. To spearhead the adoption…

PolarStar: Expanding the Scalability Horizon of Diameter-3 Networks

Kartik Lakhotia, Laura Monroe, Kelly Isham +4

We present PolarStar, a novel family of diameter-3 network topologies derived from the star product of low-diameter factor graphs. PolarStar gives the largest known diameter-3 netw…

PolarFly: A Cost-Effective and Flexible Low-Diameter Topology

Kartik Lakhotia, Maciej Besta, Laura Monroe +4

In this paper we present PolarFly, a diameter-2 network topology based on the Erdos-Renyi family of polarity graphs from finite geometry. This is a highly scalable low-diameter top…
