Energy-Efficient Server Selection Algorithms
Research Guide
What is Energy-Efficient Server Selection Algorithms?
Energy-Efficient Server Selection Algorithms are computational methods that choose optimal servers in clusters or clouds to minimize total power consumption while balancing performance metrics like latency and load.
These algorithms model server power usage with frameworks like MLPC (multi-level power consumption) and MLC (multi-level computation) for CPU-intensive processes (Kataoka et al., 2016, 61 citations). Evaluations compare energy savings across scalable clusters, showing up to 30% reductions in macro-level power draw (Kataoka et al., 2015, 33 citations). Over 10 papers from 2010-2020 focus on extensions for storage, communication, and network applications.
Why It Matters
In hyperscale data centers, these algorithms cut energy costs for providers like AWS and Google Cloud, where servers consume 1-2% of global electricity. Kataoka et al. (2016) demonstrate 20-40% power savings in clusters handling 1000+ servers without latency penalties. Enokido and Takizawa (2012) apply ETPC models to communication processes, enabling sustainable IoT deployments. Inoue et al. (2013) extend to dynamic CP/ST workloads, reducing green society impacts in edge computing.
Key Research Challenges
Modeling Multi-Level Power
Servers with multiple CPUs require MLPC and MLCM to predict power at varying loads (Kataoka et al., 2016). Challenges arise in scaling these models to heterogeneous clusters. Accurate CPU utilization forecasting remains imprecise under bursty workloads.
Trade-off Optimization
Balancing energy, latency, and cost in real-time selection demands multi-objective functions (Kataoka et al., 2015). PCB and TRB algorithms prioritize power but increase response times by 10-15%. Dynamic adaptations fail under variable traffic.
Scalability in Large Clusters
Selection overhead grows quadratically in 1000-server systems (Enokido and Takizawa, 2012). ETPC extensions handle communication but overlook network topology. Process migration adds 5-10% migration energy overhead (Duolikun et al., 2014).
