ES2 develops methodologies for efficiently operating electronic systems, including data centers, by controlling cooling resources and managing workloads to achieve optimal energy consumption.

Center Mission and Rationale

There are thousands of data centers across the United States that handle a wide spectrum of information and processing needs for the government, military, business and industry. Data center services for entertainment, e-business, finances, cloud computing and healthcare continue to grow at a dramatic rate.

 

Data centers consume massive amounts of energy and about half of this energy is wasted due to many inefficiencies in the system.   The problem is exacerbated by the technology trends that drive down the form factors of the electronics/IT equipment, resulting in high power densities. With such high heat loads, the cooling of data centers while maintaining equipment performance is one of the biggest challenges faced by data center operators.

 

Binghamton University, State University of New York, and its partners: The University of Texas at Arlington, Villanova University and The Georgia Institute of Technology have established a National Science Foundation Industry/University Cooperative Research Center (I/UCRC) in the area of energy-smart electronic systems. The I/UCRC in Energy-Smart Electronic Systems works in partnership with industry and academia to develop systematic methodologies for operating electronic systems and cooling equipment  synergistically, as dynamic self-sensing and self-regulating systems that are predictive, stable and verified in real time. The center brings together computer scientists, mechanical and electrical engineers in a synergistic multi disciplinary team to address these issues.

Research program

Energy Efficient Systems

In response to the need for new dynamic, predictive, and synergistic energy optimization and thermal management design criteria for electronic systems, the Center will focus on the development of systematic methodologies for operating electronic systems, including data centers, as dynamic self sensing and regulating systems that are predictive and verified in real time. Algorithms will be developed to control cooling resources and to assist expert system schedulers to schedule and/or migrate workload and simultaneously adjust the cooling system output to achieve optimal energy consumption. New scheduling and workload prediction and management policies need to be developed at the software level, including kernel scheduling policies to operate the IT equipment within pre-specified energy limits. Thermal management resources will also be allocated dynamically in response to the workload allocation and scheduling policies.  This is by nature an intrinsically multi-disciplinary research area integrating software algorithms at the operating system and workload scheduling levels, control systems, thermal management and hardware. New models will have direct application to a variety of electronic/computing systems ranging all the way from the chip or device level, to the system or data center level. Problem-oriented research related to improving the energy efficiency of electronic systems, including data centers, ranging from chip architectures, software design, and multi-scale thermal management techniques will be addressed during the Center’s first five year program.  

Problem-oriented research related to the industry’s search for optimizing the energy-efficiency of electronic systems and data centers will be addressed during the Center’s first five year program.  The research agenda is unique in its use of techniques that synergistically combine: (a) computing (including software and microarchitectural techniques), (b) innovative cooling solutions and thermal management techniques and, (c) adaptive, pro-active and scalable control system concepts in devising a system-level solution. The initial research portfolio includes:

Determining key intrinsic energy consumption inefficiencies at every level from devices to entire systems such as avionics, communication infrastructures, and data centers to address the inherent energy-efficiency of all components – mechanical, IT or software, efficiency in the energy delivery and conversion process and the inefficiencies in the interactions of the components within the system.


Techniques for managing data centers synergistically using predictive models for computing workload and thermal trends, driven by live models in the control loop.

 

Software techniques implemented within the kernel for implementing job scheduling and server local configuration settings based on the use of energy budgets associated with individual servers to permit predictive and synergistic management of the cooling system using a scalable control system.

 

Microarchitectural techniques for improving energy-efficiency of server chips and memory systems.

Airflow management techniques in data centers based on fast, compact models that are continuously validated with live data and using these models to drive job allocation and virtualization mechanisms to reduce the overall energy expenditures.

 Software techniques at the kernel, application and compiler levels for exploiting emerging non-volatile memory technologies in improving the intrinsic energy-efficiency of servers.

Techniques for improving the energy efficiency of buildings and containers.

Thermal Management and Controls

Several current research projects deal with modeling and managing and controlling thermal flows and cooling in and around servers, racks and floor tiles.

Waste Energy Recovery

This reserach thrust analyzes research done to date on various methods of recovering waste energy from servers for reuse. 

Workload Scheduling and Virtualization

This research thrust deals with managing workloads to run servers at peak efficiency by establishing predictive models to determine when servers should be running and when they should be placed in a hybernation state to conserve energy.

Special Activities

Hybrid AC/DC Powered Data Centers

The NSF recently awarded a "Clusters for Grand Challenges" award to ES2 and GRAPES for research in hybrid AC/DC powered data centers. Currently, there are significant power losses as AC power is distributed and converted to low-voltage DC power that is needed for chips within servers, networking and storage devices. Virtualization and other IT management techniques reduce the effective power delivery in data centers. Energy needs for data centers are significant and growing.

This cluster will do research addressing various aspects of incorporating DC power to data centers, including highlighting the advantages of using DC power, demonstrating the advantages of incorporating renewable energy sources into the power supply, establishing new metrics for AC- and DC-powered data centers, validating improvements in operational reliability and availability and examining new devices and cooling systems for DC power conversion.
