SuperComputing is the International Conference for High Performance Computing, Networking, Storage and Analysis. This workshop focuses on power consumption challenges and limitations for data centers and data networks, on opportunities to jointly optimize data center and network designs and architectures, and on innovative solutions to improve overall energy efficiency and enable sustainable communications and computing platforms, solutions and networks. Attendees will hear world-renowned and leading experts in the field share their insights and expertise and engage in stimulating discussions. The day-long workshop also includes a panel discussion with audience Q&A.


As data centers continue to grow in size and complexity in order to handle exponential growth in traffic, their power consumption is becoming increasingly important. By some estimates (from the U.S. EPA Report to Congress on Server and Data Center Efficiency, 2007), the power consumption of U.S. data centers in 2006 was 1.5% of the total energy consumed, at a cost of more than $4.5B. Power consumption is expected to double by 2011 and to require up to 7GW at peak loads. Further, overall Internet traffic (of which a large portion goes to data centers) is expected to continue to grow at annual rates of 30-60%, leading to a more than 30-fold increase in total communication traffic in the next decade.

With such exponential growth in traffic, power consumption of data centers and networks will become a critical issue, and it could ultimately limit the growth of communication services and applications. It is of vital importance to the IT and telecommunications industries to find innovative ways to improve the energy efficiency of networks and data centers, to enable sustainable communications and computing platforms, networks and solutions.

The workshop will be a full-day event with a series of presentations by distinguished experts in the fields of networking, data centers, computer science, energy efficiency, communications and computing.

The workshop's objectives are to share information, perspectives, technical challenges and ideas across different communities and organizations, leading to an end-to-end approach for improved energy efficiency that spans all layers, from hardware and components to network architecture, network management and control, to services and applications. We also seek to jump-start discussions that will extend beyond the workshop and result in collaborations for holistic and joint designs.
