This repository hosts the measurement tool developed for the SIGCOMM 2026 paper Scale-Up Networks for Large Language Models: Measurement, Implications and Optimization.
NVmesh is a specialized NVLink scale-up interconnect measurement toolkit extended from NVIDIA nvloom.
NVmesh is designed to characterize scale-up GPU interconnects in modern LLM systems, enabling fine-grained measurement, profiling, and analysis of NVLink behavior.
The codebase is currently being organized and will be open-sourced soon.
