Bring Your Own Objective: Inter-operability of Network Objectives in Datacenters
Sanjoli Narang, Anup Agarwal, Venkat Arun +1
Datacenter networks are currently locked in a "tyranny of the single objective". While modern workloads demand diverse performance goals, ranging from coflow completion times, per-…
MonkeyTree: Near-Minimal Congestion for Multi-tenant Training via Migration
Anton A. Zabreyko, Weiyang Wang, Manya Ghobadi
We present MonkeyTree, the first system to mitigate network congestion in multi-tenant GPU clusters through job-migration based defragmentation rather than network-layer techniques…
LINC: An In-Network Coding Approach to Tame Packet Loss in Hybrid Wireless-Fiber Backbones
Benoit Pit-Claudel, Muriel Médard, Manya Ghobadi
The emergence of ultra-low latency applications, such as financial transactions, has driven the development of hybrid backbone networks that rely on fiber, satellite, and microwave…
Checkmate: Zero-Overhead Model Checkpointing via Network Gradient Replication
Ankit Bhardwaj, Weiyang Wang, Jeremy Carin +2
This paper presents Checkmate, a system that enables per-iteration checkpointing in DNN training without any training slowdown. The traditional approach to checkpointing requires a…
Scalable Routing in a City-Scale Wi-Fi Network for Disaster Recovery
Ziqian Liu, Om Chabra, James Lynch +3
In this paper, we present a new city-scale decentralized mesh network system suited for disaster recovery and emergencies. When wide-area connectivity is unavailable or significant…
