UD25 | LLMs Without HPC? Good Luck! — Andres Algaba (VUB)

Описание: Recorded presentation from VSC User Day 2025

In this talk, Andres Algaba (Vrije Universiteit Brussel) explains why large language models (LLMs) fundamentally depend on high-performance computing infrastructure.

The presentation covers:

What large language models are and how next-token prediction works
Why scaling data, parameters, and compute directly increases model capabilities
The role of reinforcement learning and reasoning tokens in modern LLMs
Why inference workloads require massive parallelism and GPU memory
How batching, large contexts, and KV-caching drive hardware requirements
Why demand for HPC resources continues to increase with LLM research and applications

This talk is based on real research conducted at the VUB Data Analytics Lab and includes concrete examples of LLM inference workloads, GPU memory usage, and emerging research directions in interpretability, reasoning, and scientific impact.
