Autonomic Middleware for Green Data Centers

Data center energy consumption is a major and growing concern worldwide. Among many alarming trends, half of all data centers are now suffering from insufficient power and cooling capacity, and power has recently become the second-highest operating cost. Moreover, data centers now account for over 5% of all global emissions of CO2. In response to these concerns, researchers are exploring a myriad of different methods for reducing power consumption at a wide range of spatial and temporal scales. At the finest level of granularity, chip manufacturers are including processor controls that allow the processor frequency and voltage to be reduced for power savings. To a certain degree, these control knobs can be managed at the platform or operating system level based on performance counters, cpu utilization, and other low-level metrics.

In this talk, I explore the role that autonomic middleware can play in reducing energy consumption in data centers. Because the actual and desired application-level metrics are accessible at the middleware level, there are several opportunities for saving energy that are simply not available at the platform and OS levels. For example, middleware that is cognizant of performance-related Service Level Agreements can deliberately reduce the use of computational resources such that the desired performance levels are not overachieved, and less energy is consumed. I will describe several theoretical and experimental studies that demonstrate that, with the right algorithms and architecture, autonomic middleware can work either unilaterally or in concert with platform-level power control mechanisms to achieve significant energy savings. I will also discuss a potentially broader role for autonomic middleware that looks upward to the data center level, working in tandem with power distribution units and cooling units to intelligently manage resources to satisfy performance and availability objectives while saving energy.

Automotive Adaptation: The Challenges of the Automotive Cyber-Physical System

The Automobile historically has had to adapt to many different modes of usage. However the modes of usage and optimization of operation of usage are largely handled by the most adaptable component of the vehicle ... the driver. As society and customer expectations change, more of the functionality of the future is dependant on self-adaptivity and self-management to support the evolution of vehicle capabilities. We look at what the capabilities of the future and the challenges to achievement to set a trajectory for the needs for self-managing systems and their underlying architectures for the vehicle domain.
