“Pathways to Actionable ModSim for Computing Infrastructure“
17 February 2025
Abstract
Large computing facilities have become critical resources across many research areas such as high energy physics, climate science, and artificial intelligence. Modeling and simulation (ModSim) of this infrastructure has become essential to ensuring they are deployed and managed to meet productivity and efficiency goals. However, ModSim methodologies currently lack the maturity to accurately predict the behavior of these infrastructure at scale with the required fidelity. There is a need for more actionable models of these important facilities to support design and operational decision-making.
This talk explores challenges in ModSim for large-scale computing infrastructure. It will discuss limitations of current methodologies – such as discrete event and agent-based modelling – in heterogeneous environments and present novel hybrid modelling strategies for more scalable and accurate simulations. Finally, it will highlight opportunities in the wider research ecosystem for advancing the field of ModSim and co-design of large-scale computing facilities and infrastructure.

Kevin A. Brown is the inaugural Walter Massey Fellow at Argonne National Laboratory. His main area of research focuses on performance measurement, analysis, and simulation of HPC infrastructure. He leads and co-leads several multi-institutional projects aimed at designing more efficient communication infrastructure for HPC systems and distributed environments as well as improving tools for the modeling and simulation of emerging infrastructure.
Kevin received his B.Sc. from the University of Technology, Jamaica (UTech) and his M.Sc. and Ph.D. in Mathematical and Computing Science from the Tokyo Institute of Technology. His prior work experience includes serving as a Unix Systems Administrator at Digicel (Jamaica) Ltd. and as a postdoctoral appointee in the Argonne Leadership Computing Facility focused on exascale interconnect performance evaluation.
