Tuning Collective Patterns to Alleviate Congestion in Shared AI Clusters
Eashan Gupta, Yongzhou Chen, Apoorve Mohan +3
Distributed AI training involves recurring rounds of data exchange between multiple pairs of GPU nodes. Slowdown in even one flow due to congestion can cause the entire communicati…
DBO: Response Time Fairness for Cloud-Hosted Financial Exchanges
Prateesh Goyal, Eashan Gupta, Ilias Marinos +3
In this paper, we consider the problem of hosting financial exchanges in the cloud. Financial exchanges require predictable, equal latency to all market participants to ensure fair…
Controlling Congestion via In-Network Content Adaptation
Yongzhou Chen, Ammar Tahir, Radhika Mittal
Realizing that it is inherently difficult to precisely match the sending rates at the endhost with the available capacity on dynamic cellular links, we build a system, Octopus, tha…
Site-to-Site Internet Traffic Control
Frank Cangialosi, Akshay Narayan, Prateesh Goyal +3
Queues allow network operators to control traffic: where queues build, they can enforce scheduling and shaping policies. In the Internet today, however, there is a mismatch between…
High Throughput Cryptocurrency Routing in Payment Channel Networks
Vibhaalakshmi Sivaraman, Shaileshh Bojja Venkatakrishnan, Kathy Ruan +5
Despite growing adoption of cryptocurrencies, making fast payments at scale remains a challenge. Payment channel networks (PCNs) such as the Lightning Network have emerged as a via…
Revisiting Network Support for RDMA
Radhika Mittal, Alexander Shpiner, Aurojit Panda +4
The advent of RoCE (RDMA over Converged Ethernet) has led to a significant increase in the use of RDMA in datacenter networks. To achieve good performance, RoCE requires a lossless…
Universal Packet Scheduling
Radhika Mittal, Rachit Agarwal, Sylvia Ratnasamy +1
In this paper we address a seemingly simple question: Is there a universal packet scheduling algorithm? More precisely, we analyze (both theoretically and empirically) whether ther…
Low latency via redundancy
Ashish Vulimiri, P. Brighten Godfrey, Radhika Mittal +3
Low latency is critical for interactive networked applications. But while we know how to scale systems to increase capacity, reducing latency --- especially the tail of the latency…
