Dr. Erich Strohmaier
Computer Scientist, Lawrence Berkeley National Laboratory, USA Dr. Erich Strohmaier is Computer Scientist in the Future Technologies Group of the Computational Research Division at LBNL. His current research focuses on performance characterization, evaluation, modeling, and performance engineering. From 1995-2000 he worked in the Computer Science Department of the University of Tennessee at Knoxville. From 1990-1995 he worked at the University of Mannheim where he was responsible for the Parallel Computing Group. He is, along with Hans Meuer and Jack Dongarra founder of the TOP500 project. Dr. Erich Strohmaier presents at the Session Opening Session 'Highlights of the 29th TOP500 List' Abstract: Since its beginning in 1993, the June edition of the TOP500 ranking of the fastest supercomputers in the world is published at the International Supercomputer Conferences. During the Opening Session of ISC’07 the new list will be released and highlights about the new list and changes in the market for supercomputing will be presented. Information on all previous TOP500 lists is to be found at: http://www.top500.org/ Dr. Erich Strohmaier chairs the Session Hot Seat Session Part II Dr. Erich Strohmaier organizes the BoF Session: 'Energy Consumption of Supercomputers' Abstract: For decades, the notion of "performance of computer" has been synonymous with "raw speed" as measured in FLOP/S. This isolated focus has ultimately led to supercomputers that consume egregious amounts of electrical power. Other performance metrics have been largely ignored, e.g., power efficiency, space efficiency, reliability, availability, and usability. As a consequence the total cost of ownership (TCO) of a supercomputer has incresed extraordinarily.To raise awareness and facilitate discussion of these issues, developing new ranking systems that make use of alternative performance metrics would be helpful. This BoF will present an overview of the power consumption trends over the last decade. It will discuss new performance and power-related metrics that could be used to rank systems differently and outline ways to measure them. We will also discuss how best to present and use these data and their relationship to the TOP500 and Green500 List. |
