Théo SAILLANT is currently a PhD candidate at ENS Paris-Saclay (previously ENS Cachan) in collaboration with the CEA. His research project is about Machine Learning applications for HPC. He is focusing on exploring data that can be obtain with very low incidence on computing performances for better understanding and monitoring of computer centers with little intervention. The goal is to automatically classify jobs according to the limiting factor and power usage with the data already available in practice on jobs in production.
