Anand Sivasubramaniam, ACM Fellow and IEEE Fellow, is a Distinguished Professor of Computer Science and Engineering at Penn State. He received his B.Tech from IIT Madras, and the MS and Ph.D. degrees, all in computer science, from Georgia Tech. He has been at Penn State since 1995, where he has spearheaded several research projects in high performance computing, energy-efficient computer systems design, sustainable data centers, and using computing for tackling sustainability issues on a broader scale including building energy management, renewable energy integration and efficient water distribution for utilities. He has worked with industry on many of these issues. Apart from an NSF Career award, he has received 3 Google Research Awards, 3 IBM Faculty Awards, and a HP Innovation award.
Power consumption of computing systems has become a primary criterion impacting their design and deployment in the field. Power is important not just for the untethered battery based mobile devices, but also in high end servers where the power envelope has begun to dictate their maximum performance. Such high end servers are also the building blocks of large multi-megawatt datacenters which house hundreds of thousands of these servers, leading to serious concerns about their cost, scalability and ecological footprint. These concerns are a consequence of not just how much total energy is expended, but also when and how this energy is expended. The hardware and software community has developed several computing knobs for power modulation to deal with these issues. However, energy storage has, until recently, been outside the purview of the computer systems community. In this talk, I will emphasize the need for treating power as a primary resource for explicit allocation and control, and the importance of bringing energy storage into the purview of computer systems management. I will specifically talk about provisioning energy storage in the datacenter to answer the “what”, “where” and “how much” questions, and mechanisms for managing the power draw by leveraging this resource. I will also highlight some of the unique opportunities and challenges that make power management different from that for managing other resources, thus providing a rich and challenging set of hardware and software issues to drive future research.
