Trivance: Latency-Optimal AllReduce by Shortcutting Multiport Networks

Anton Juerss, Vamsi Addanki, Stefan Schmid

AllReduce is a fundamental collective communication operation in distributed computing and a key performance bottleneck for large-scale training and inference. Its completion time…

The Harmonic Policy for Online Buffer Sharing is (2 + ln n)-Competitive: A Simple Proof

Vamsi Addanki, Julien Dallot, Leon Kellerhals +2

The problem of online buffer sharing is expressed as follows. A switch with output ports receives a stream of incoming packets. When an incoming packet is accepted by the switc…

SHORTCUT: In-Collective Topology Reconfiguration for Low-Latency AllReduce

Sarah-Michelle Hammer, Stefan Schmid, Anton Juerss +2

Distributed ML training relies on efficient AllReduce communication to aggregate data across nodes. In this setting, reconfigurable optical interconnects offer high-bandwidth, ener…

Learning Minimum Linear Arrangement of Cliques and Lines

Julien Dallot, Maciej Pacut, Marcin Bienkowski +2

In the well-known Minimum Linear Arrangement problem (MinLA), the goal is to arrange the nodes of an undirected graph into a permutation so that the total stretch of the edges is m…

Dependency-Aware Online Caching

Julien Dallot, Amirmehdi Jafari Fesharaki, Maciej Pacut +1

We consider a variant of the online caching problem where the items exhibit dependencies among each other: an item can reside in the cache only if all its dependent items are also…

Credence: Augmenting Datacenter Switch Buffer Sharing with ML Predictions

Vamsi Addanki, Maciej Pacut, Stefan Schmid

Packet buffers in datacenter switches are shared across all the switch ports in order to improve the overall throughput. The trend of shrinking buffer sizes in datacenter switches…

PowerTCP: Pushing the Performance Limits of Datacenter Networks

Vamsi Addanki, Oliver Michel, Stefan Schmid

Increasingly stringent throughput and latency requirements in datacenter networks demand fast and accurate congestion control. We observe that the reaction time and accuracy of exi…
