Advance registration – at lower rates – is now open for the 20th anniversary International Supercomputer Conference (ISC2005) to be held June 21-24. The conference program for ISC2005 is also now available at www.supercomp.de/index.php?s=conference&unterseite=overview . “In honor of reaching our 20th anniversary conference, we have drawn up a program which we believe is one of the strongest – if not the best – we have presented to date,” said Conference Chairman Prof. Hans Werner Meuer of the University of Mannheim. “With invited speakers from around the world, ISC2005 provides a global perspective on the multi-faceted world of HPC.” Under the theme of “Applications, Architectures, Trends,” ISC2005 offers three days of intensive technical sessions and plenty of networking opportunities to provide attendees with a comprehensive and compact overview on HPC topics presented by world-renowned scientists and experts. The sessions will cover such areas as key applications, requirements for HPC systems software, innovative supercomputer architectures, integrated data and information management, and the popular “hot seat” sessions, during which specially selected experts acting as “inquisitors” pose pithy questions to representatives from leading HPC vendors. The ISC2005 program will also include a look at future trends, as well as an HPC retrospective. There will also be a one-day, hands-on tutorial covering “Interconnect Architectures in Practice” on Tuesday, June21. “HPC continues to see many exciting developments in all aspects of the field, and many of the people behind those innovative ideas will be in Heidelberg to share their experience and their expertise,” said Prof. Meuer. “We have thoughtfully assembled a program that will deliver the highest levels of thought and leadership on the subject of HPC applications, architectures and trends.” The conference, which is conducted in English, has a well-established reputation for presenting well-founded, precise and up-to-date information in a collegial setting. In addition to the technical program, ISC2004 features an extensive three-day exhibition by the world’s leading vendors of HPC systems and services. Attendees who register for ISC2005 before Sunday, May 22, will benefit from the advance registration rates, saving more than 200 euros over the on-site registration fees.

The annual conference is held in Heidelberg, the home of Germany's oldest university as well as a thriving modern research community.
