Network Design for Wafer-Scale Systems with Wafer-on-Wafer Hybrid Bonding
Patrick Iff, Tommaso Bonato, Maciej Besta +2
Transformer-based large language models are increasingly constrained by data movement as communication bandwidth drops sharply beyond the chip boundary. Wafer-scale integration usi…
Demystifying NCCL: An In-depth Analysis of GPU Communication Protocols and Algorithms
Zhiyi Hu, Siyuan Shen, Tommaso Bonato +6
The NVIDIA Collective Communication Library (NCCL) is a critical software layer enabling high-performance collectives on large-scale GPU clusters. Despite being open source with a…
Spritz: Path-Aware Load Balancing in Low-Diameter Networks
Tommaso Bonato, Ales Kubicek, Abdul Kabbani +3
Low-diameter topologies such as Dragonfly and Slim Fly are increasingly adopted in HPC and datacenter networks, yet existing load balancing techniques either rely on proprietary in…
SMaRTT: Sender-based Marked Rapidly-adapting Trimmed & Timed Transport
Tommaso Bonato, Abdul Kabbani, Ahmad Ghalayini +10
With the rapid growth of artificial intelligence (AI) workloads in datacenters, the Ultra Ethernet Consortium (UEC) has defined a new high-performance transport layer to deliver th…
REPS: Recycled Entropy Packet Spraying for Adaptive Load Balancing and Failure Mitigation
Tommaso Bonato, Abdul Kabbani, Ahmad Ghalayini +7
Next-generation datacenters require highly efficient network load balancing to manage the growing scale of artificial intelligence (AI) training and general datacenter traffic. How…
Flowcut Switching: High-Performance Adaptive Routing with In-Order Delivery Guarantees
Tommaso Bonato, Daniele De Sensi, Salvatore Di Girolamo +4
Network latency severely impacts the performance of applications running on supercomputers. Adaptive routing algorithms route packets over different available paths to reduce laten…
