READEX Tool Suite for Energy-efficiency Tuning of HPC Applications

Abstract

The European Union Horizon 2020 READEX project is developing a tool suite for dynamic energy tuning of HPC applications. The tool suite performs an analysis during design-time before production run to construct a tuning model encapsulated with the best-found configurations that are then fed to the runtime tuning library. The library switches the configurations at runtime to adapt the application for energy-efficiency.
