Abstract: High Performance Computing (HPC) applications are highly complex and demand ecient execution. Energy require- ment of current petascale and future exascale systems is a major cause for concern, and it is crucial to improve the energy-eciency of the applications that run on these systems. A signi cant source of improvement for applications is that they commonly exhibit dynamic resource requirements. Consequently, such dynamism in an application presents opportunity to tailor the utilisation of resources in the HPC system based on the requirement...
