My research area is High Performance Computing (HPC), and in particular parallel and distributed computing for scientific application workloads. For example, I have done work in the following areas:

Current Research Projects

Most of my current research focuses on the simulation of parallel and distributed computing systems, with a large emphasis placed on HPC systems. Two key projects are:

The SimGrid project, which I initiated more than 20 years ago but has taken a life of its own thanks to a bunch of talented people who've made it better than I could ever have, is a simulation framework for building scalable, accurate, simulators of parallel/distributed applications, systems, and platforms.
The WRENCH project is a simulation framework that sits on top of SimGrid and makes it possible to implement scalable and accurate simulators of complex cyberinfrastructure systems quickly and easily.
