HAPMoE: Heterogeneity-Aware Automatic Parallelism Planning for Mixture-of-Experts Models Training

Mengyuan Fan, Peizhuang Cong, Zixiao Huang +7

As model sizes continue to scale, distributed training has become inevitable. Automatic parallelization techniques can derive efficient training parallelism strategies at low cost…

Convolution for Large Language Models

Yuchuan Tian, Yingte Shu, Wei He +7

Large language models (LLMs) largely rely on Transformers, where self-attention provides global token interaction but does not explicitly encode the locality of natural language. W…

Elastic-dLLM: Position Preserving Context Compression and Augmentation of Diffusion LLMs

Junyi Wu, Tianchen Zhao, Shaoqiu Zhang +3

Unlike autoregressive models, which generate one token at a time, dLLMs denoise a chunk of [MASK] tokens jointly and sample one or more tokens per step; despite enabling parallel d…

DynaTrain: Fast Online Parallelism Switching for Elastic LLM Training

Yuanqing Wang, Yuchen Zhang, Hao Lin +9

Modern large language model (LLM) training is inherently dynamic: resource fluctuations, RLHF phase shifts, and cluster elasticity continually reshape the optimal parallelism layou…

FUSCO: High-Performance Distributed Data Shuffling via Transformation-Communication Fusion

Zhuoran Zhu, Chunyang Zhu, Hao Lin +9

Large-scale Mixture-of-Experts (MoE) models rely on \emph{expert parallelism} for efficient training and inference, which splits experts across devices and necessitates distributed…

SpeContext: Enabling Efficient Long-context Reasoning with Speculative Context Sparsity in LLMs

Jiaming Xu, Jiayi Pan, Hanzhen Wang +4

In this paper, we point out that the objective of the retrieval algorithms is to align with the LLM, which is similar to the objective of knowledge distillation in LLMs. We analyze…
