Extending the Life of HPC Systems in Resource Constrained Environments: Mapping Productivity-Energy Trade-offs in Memory-Bound Workloads via DVFS and Core Scaling on Repurposed Hardware

This work examines the impact of limiting active cores on repurposed nodes and introduces deep C-state power-gating, fully saturated workloads, and hardware-level power measurements to address viability in complex applications such as OpenFOAM.
