NEURON-Fabric: Architecture-Runtime Co-Design for Controlled Low-Bit Gradient Communication
Ziqiang Wang, Changcheng Huang, Chung-Horng Lung
Large-scale neural-network training repeatedly aggregates gradients across devices, making communication a central cost in distributed learning. Low-bit gradient aggregation can re…
NEURON-Fabric: CXL-Side Low-Bit Gradient Aggregation for Distributed Training
Ziqiang Wang, Changcheng Huang, Chung-Horng Lung
In large-model distributed training, especially large language model workloads, gradient All-Reduce increasingly stresses the memory and communication path. This paper asks whether…
Green Traffic Engineering for Satellite Networks Using Segment Routing Flexible Algorithm
Jintao Liang, Pablo G. Madoery, Chung-Horng Lung +2
Large-scale low-Earth-orbit (LEO) constellations demand routing that simultaneously minimizes energy, guarantees delivery under congestion, and meets latency requirements for time-…
Green Satellite Networks Using Segment Routing and Software-Defined Networking
Jintao Liang, Pablo G. Madoery, Chung-Horng Lung +2
This paper presents a comprehensive evaluation of network performance in software defined networking (SDN)-based low Earth orbit (LEO) satellite networks, focusing on the Telesat L…
