LLMxHPC: 2025 International Workshop on Large Language Models (LLMs) and HPC

September 2, 2025 in Edinburgh, United Kingdom

Co-hosted with the 2025 IEEE Cluster Conference

https://llmhpc.github.io/2025/

Submission deadline: June 20, 2025

=============================================

## WORKSHOP SCOPE

High-Performance Computing (HPC) systems have become critical for meeting the computational and data-intensive needs of training Large Language Models (LLMs). Simultaneously, in the domain of HPC research, LLMs are emerging as transformative tools to understand and improve HPC system productivity and efficiency. There are clear synergies between these areas and meaningful coordination of efforts holds great promise. This workshop brings together researchers and developers to explore the intersection of HPC and LLMs, offering a comprehensive look at how these two domains can mutually benefit and drive each other's advancement. The workshop has two key focus areas: (i) co-design and deployment of HPC systems to support LLM training and (ii) using LLMs to understand and optimize/tune HPC systems. A combination of paper presentations, panel discussion, and keynote will be included in the program to highlight salient research and development activities, promote diverse perspectives and visions, and stimulate discussion in the community.

## TOPICS

Topics to be covered in this workshop include, but are not limited to,

• The computational and data needs of LLM training
