Editorial for the ISC’09 Scientific Day Proceedings

The International Supercomputing Conference started in 1986 as the “Supercomputer Seminar” organized by Prof. Hans Meuer, then director of the computer center and professor for computer science at the University of Mannheim (Germany). Since these early days the annual conference became a major international event in the HPC community. As the conference grew bigger, it moved from Mannheim over Heidelberg and Dresden to Hamburg. In 2009 we expect more than 1,500 participants who will attend the exhibition and the various scientific and technical sessions. Over the years we decided to strengthen the scientific part of the conference and present selected talks on relevant research results in the field of HPC. These scientific sessions started in 2007 and preceded the conference. Slides and accompanying papers were made available via the conference web site. For 2009 we changed this concept and give the scientific part of the conference a higher ranking and visibility. The scientific sessions now merge into the Scientific Day, which is an integral part of the conference. The Scientific Day is scheduled in the afternoon of the first day of the conference. The call for participation was issued in winter 2008 and invited researchers and developers to submit latest results of their work as full research papers to the program committee of the Scientific Day. We solicited contributions in the fields of applications, system architecture, and large-scale system
