Frontier: Towards Comprehensive and Accurate LLM Inference Simulation

Yicheng Feng, Xin Tan, Yangtao Deng +3

Modern LLM serving is no longer homogeneous or monolithic. Production systems now combine disaggregated execution, complex parallelism, runtime optimizations, and stateful workload…

OrchestrRL: Dynamic Compute and Network Orchestration for Disaggregated RL

Xin Tan, Yicheng Feng, Yu Zhou +3

Disaggregating the generation and training stages in RL is widely adopted to scale LLM post-training. There are two critical challenges here. First, the generation stage often beco…

DistTrain: Addressing Model and Data Heterogeneity with Disaggregated Training for Multimodal Large Language Models

Zili Zhang, Yinmin Zhong, Yimin Jiang +6

Multimodal large language models (LLMs) empower LLMs to ingest inputs and generate outputs in multiple forms, such as text, image, and audio. However, the integration of multiple m…

Frontier: Simulating the Next Generation of LLM Inference Systems

Yicheng Feng, Xin Tan, Kin Hang Sew +3

Large Language Model (LLM) inference is growing increasingly complex with the rise of Mixture-of-Experts (MoE) models and disaggregated architectures that decouple components like…

InfiniteHBD: Building Datacenter-Scale High-Bandwidth Domain for LLM with Optical Circuit Switching Transceivers

Chenchen Shou, Guyue Liu, Hao Nie +11

Scaling Large Language Model (LLM) training relies on multi-dimensional parallelism, where High-Bandwidth Domains (HBDs) are critical for communication-intensive parallelism like T…

Teola: Towards End-to-End Optimization of LLM-based Applications

Xin Tan, Yimin Jiang, Yitao Yang +1

Large language model (LLM)-based applications consist of both LLM and non-LLM components, each contributing to the end-to-end latency. Despite great efforts to optimize LLM inferen…
