JanusPipe: Efficient Pipeline Parallel Training for Machine Learning Interatomic Potentials

ICML 2026poster

Discovering atom-level phenomena requires molecular dynamics (MD) simulations with ab initio accuracy. Machine learning interatomic potentials (MLIPs) enable stable, high-accuracy MD simulations, and their models exhibit scaling-law trends similar to large language models. However, the lack of scala…

Efficient Long Context Fine-tuning with Chunk Flow

ICML 2025poster

Long context fine-tuning of large language models(LLMs) involves training on datasets that are predominantly composed of short sequences and a small proportion of longer sequences. However, existing approaches overlook this long-tail distribution and employ training strategies designed specifically…

Skrull: Towards Efficient Long Context Fine-tuning through Dynamic Data Scheduling

NeurIPS 2025poster

Long-context supervised fine-tuning (Long-SFT) plays a vital role in enhancing the performance of large language models (LLMs) on long-context tasks. To smoothly adapt LLMs to long-context scenarios, this process typically entails training on mixed datasets containing both long and short sequences.…
