The Seventh Workshop on
The 7th Workshop on High-Performance, Power-Aware Computing (HPPAC
2011) will be held
May 16, 2011 in Anchorage, Alaska, USA,
in conjunction with the
25th Annual
International Parallel & Distributed Processing Symposium (IPDPS
2011), May
May 16-20, 2011, Anchorage, Alaska, USA
Keynote Address Bronis R. de Supinski (LLNL) Power and energy are central concerns for both large scale systems applied to scientific workloads and corporate data centers and will become even more important as we look towards exascale systems. Systems such as Lawrence Livermore National Laboratory’s BlueGene/L and Oak Ridge National Laboratory’s Jaguar already have over 100,000 processor cores, while the planned ASC Sequoia system at LLNL will have over 1.5 million cores when it is deployed in FY12. While hardware techniques have proven sufficient to fit these systems within the power budgets of these HPC centers, we anticipate that continued increases in processing power will require application-level power-aware techniques. Our initial experiences demonstrate that substantial energy savings are possible with current systems for programs using the MPI and OpenMP programming models. In this talk, I will detail energy saving techniques such as load smoothing based on dynamic voltage and frequency scaling and dynamic concurrency throttling and their application to large scale scientific workloads. Scope High-performance computing is and has always been performance-oriented. However, a consequence of the push towards maximum performance is increased energy consumption, especially in datacenters and supercomputing centers. Moreover, as peak performance is rarely attained, some of this energy consumption results in little or no performance gain. In addition, large energy consumption costs datacenters and supercomputing centers a significant amount of money and wastes natural resources. The main goal of this workshop is to provide a timely forum for the exchange and dissemination of new ideas, techniques, and research in high-performance, power-aware computing (HPPAC). HPPAC will present research that reduces (1) power consumption, (2) energy consumption, or (3) heat generation with little or no performance penalty in high-performance computing systems. In effect, the workshop aims to move towards "greener" solutions for datacenters and supercomputing centers. Examples include Green Destiny (2001), The Green Grid (2007), The Green500 List (2007), and the INRIA Green-Net Initiative (2008).
