Simulation-driven evaluation of cyberinfrastructure systems (2024)

A well-known Cyberinstructure (CI) challenge is to develop runtime systems that can execute application workloads effectively and efficiently. The overarching goal of this project is to transform the way in which these systems are evaluated, so that their capabilities can be evolved based on a sound, quantitative experimental science approach. The key idea is to step away from traditional experimental evaluations performed on actual cyberinfrastructure deployments, and instead to rely on simulation that accurately models the functional and performance behaviors of software and hardware stacks of interest. Simulation can transform the way in which cyberinfrastructure systems are evaluated because it can make these evaluations fast, reproducible, perfectly observable, and accurate. The main simulation technology used for this work is the WRENCH simulation framework, which builds on the state-of-the-art SimGrid simulation framework
