ECE graduate student Luca Parolini has won an APC Fellowship for Data Center Efficiency Research.
Data centers account for nearly 1.5% of total electricity consumption in the U.S. at a cost of approximately $4.5 billion per year. Parolini's research will lead to innovations in data center management developing a unified, thermal-computational control scheme that implements the most appropriate trade-off between minimizing power consumption and satisfying complex workload demands. More broadly, his research will lead to new approaches to the hierarchical, distributed control of large-scale cyber-physical systems.
Parilini proposes a control scheme based on a holistic and modular approach that supports: compositional modeling to address alternative data center architectures, multi-scale temporal and spatial abstractions and decompositions, stochastic influences from the environment and workloads, extensibility to incorporate emerging technologies (e.g., solid-state storage, liquid cooling), and direct control of customer-specific performance. The derived control strategies will leverage degrees of freedom that are not currently considered as variables that can be manipulated to improve data center efficiency.
