SolarCore: Solar energy driven multi-core architecture power management

Chao Li, Wangyuan Zhang, Chang-Burm Cho, Tao Li
2011 2011 IEEE 17th International Symposium on High Performance Computer Architecture  
To this end, we propose SolarCore, a solar energy driven, multi-core architecture power management scheme that combines maximal power provisioning control and workload run-time optimization.  ...  While efforts have been made to improve the performance-per-watt, conventional architecture power management schemes incur significant solar energy loss since they are largely workload-driven and unaware  ...  Acknowledgements This work is supported in part by NSF grant 0845721(CAREER) and by Microsoft Research Safe and Scalable Multi-core Computing Award.  ...

Application configuration selection for energy-efficient execution on multicore systems

Shinan Wang, Bing Luo, Weisong Shi, Devesh Tiwari
2016 Journal of Parallel and Distributed Computing  
Selecting appropriate run-time factors, however, is one of the most challenging tasks because the run-time factors are architecture-specific and workload-specific.  ...  Modern computer systems are designed to balance performance and energy consumption.  ...  Li et al. propose SolarCore, a solar energy driven, multi-core architecture power management scheme that combines maximal power provisioning control and workload run-time optimization [36] .  ...

Green-Up: under-provisioning power backup infrastructure for green datacenters

Xu Zhou, Zhibin Yu
2019 CCF Transactions on High Performance Computing  
Power source management identifies the suitable power source for power backup whereas power load management selects the best power capping techniques for under-provisioning power backup infrastructure.  ...  It contributes two novel techniques: power source and power load managements.  ...  SolarCore employs core-level throttling techniques on multi-core systems to adjust server power when solar power fluctuates (Li et al. 2011) .  ...

An Energy-Efficient Strategy for Microcontrollers

Huanjie Wu, Chun Chen, Kai Weng
2021 Applied Sciences  
It is well known that energy is the integral of power over time. Thus, our view is that both power and time should be carefully considered to achieve better energy efficiency.  ...  A series of test sets are designed to validate our hypotheses for improving energy efficiency. The experimental results suggest that time has no less impact on energy consumption than power.  ...  [11] proposed a solar energy driven, multi-core architecture power management scheme called SolarCore, which is capable of achieving the optimal operation condition of solar panels autonomously under  ...

Active low-power modes for main memory

Qingyuan Deng
Main memory is responsible for a significant fraction of the energy consumed by servers. Prior work has focused on exploiting memory low-power states to conserve energy.  ...  The second technique, called CoScale, coordinates the CPU and main memory active low-power modes to avoid instability and increase energy savings.  ...  Previous works such as SolarCore [53] and Parasol [27] have leveraged both active and idle low-power states of the CPU and server to make good use of the solar power.  ...
