DeepPower: Deep Reinforcement Learning based Power Management for Latency Critical Applications in Multi-core Systems
Jingrun Zhang, Guangba Yu, Zilong He, Liang Ai, Pengfei Chen · 2023
Latency-critical (LC) applications are widely deployed in modern datacenters. Effective power management for LC applications can yield significant cost savings. However, it poses a significant challenge in maintaining the desired Service Level Aggrement (SLA) levels. Prior researches have mainly emphasized predicting the service time of request and utilize heuristic algorithms for CPU frequency adjustment. Unfortunately, the control granularity is limited to the request level and manual feature selection is needed.
