A low-cap power budget is challenging for exascale computing. Dynamic Voltage and Frequency Scaling (DVFS) and Uncore Frequency Scaling (UFS) are the two widely used techniques for limiting the HPC application's energy footprint. However, existing approaches fail to provide a unified solution that can work with different types of parallel programming models and applications. This paper proposes Cuttlefish, a programming model oblivious C/C++ library for achieving energy efficiency in multicore…

Improving Energy Efficiency in Memory-constrained Applications Using Core-specific Power Control
An experimental memory study presented on modern CPU architectures, Intel Sandybridge and Haswell, identifies a metric, TORo_core, that detects bandwidth saturation and increased latency that is used to construct a dynamic policy applied at coarse and fine-grained levels to modulate per-core power controls on Haswell machines.
Automatic runtime frequency-scaling system for energy savings in parallel applications
A novel runtime system that maximizes energy saving by selecting appropriate values for DVFS and throttling in parallel applications and applies frequency scaling considering both the CPU offload, provided by the network-interface card, and the architectural stalls during computation is proposed.
Using Per-Loop CPU Clock Modulation for Energy Efficiency in OpenMP Applications
This work takes advantage of the low transition overhead of CPU clock modulation and applies it to fine-grained Open MP parallel loops to achieve multi-frequency execution of Open MP applications that achieves better energy-delay trade-off than any single frequency setting.

A case for application-oblivious energy-efficient MPI runtime
Energy Aware MPI (EAM) is proposed and implemented --- an application-oblivious energy-efficient MPI runtime that uses a combination of communication models for common MPI primitives and an online observation of slack to maximize energy efficiency and to honor performance degradation limits.
Emprical study on Reducing Energy of Parallel Programs using Slack Reclamation by DVFS in a Power-scalable High Performance Cluster
A new algorithm is proposed that reduces energy consumption in a parallel program executed on a power-scalable cluster using DVFS, which reclaims slack time by changing the voltage and frequency, which allows a reduction in energy consumption without impacting on the performance of the program.
Using multiple energy gears in MPI programs on a power-scalable cluster
This paper presents a framework for executing a single application in several frequency-voltage settings and shows that more than half of the NAS benchmarks exhibit a better energy-time tradeoff using multiple gears than using a single gear.
An Adaptive Core-Specific Runtime for Energy Efficiency
An Adaptive Core-specific Runtime (ACR) that dynamically adapts core frequencies to workload characteristics, and examples of both reductions in power and improvement in the average performance are presented.
Just In Time Dynamic Voltage Scaling: Exploiting Inter-Node Slack to Save Energy in MPI Programs
This paper presents a system called Jitter, which reduces the frequency on nodes that are assigned less computation and therefore have slack time, and the goal of Jitter is to attempt to ensure that they arrive "just in time" so that they avoid increasing overall execution time.
