Large Language Models are in trend, however, increasing the models size implies the design and deployment of more complex infrastructures. Distributed training is needed due to the memory constraints, increasing the infrastructure size and the likelihood of a failure of any device, which increase operating expenses and resource waste. Therefore, an effective monitoring of failures demands a thorough understanding of the infrastructure considering the interplay of metrics belonging to inter/intra-host network metrics, CPUs, NPUs, GPUs, communication patterns as well as specifics of an LLM training. The objective of this project is to develop a framework for detecting and predicting failures in Large Language Models, specifically Mixture-of-Experts architectures based on gaining in-depth analysis and understanding of failure mechanisms in communication, computation and storage components, during training and inference.

We focus on the following topics: understanding and analyzing signals generated during LLM training, simulating scenarios through failure injection, understanding cross-effects between components in large Al infrastructures, monitoring and interpreting data from physical layer (hardware), data layer (storage and transfer), computational layer and application layer (models). We aim at learning joint representations from the multiple sources of system data to detect anomalies and their root-causes. All these will entail designing a general method, implementing a prototype in the context of existing open-source systems, and experimentally evaluating the prototype with a test data using experimental and production data.

The possibility of a PhD is given.
