Supercomputer Seminar in Mannheim
- German supercomputer conference goes international
- Ad Emmen
- With a one day Executive Update, the most important German HPCN event, the Mannheim Supercomputer Seminar went international. We report on the TOP500 , the SuParCup, and the trends in HPCN in Europe and the USA from the experts that Hans Meuer flew in. In the second issue of PrimeurLive! from Mannheim, to be published just after the Seminar, we report on the next two days of the Seminar.
Industry news
- ASCI Red now first in the new TOP500 list
- Ad Emmen
- The ASCI Red machine at Sandia national laboratories has taken over the first place in the TOP 500 supercomputer list from the Hitachi machine at Tsukuba. This was revealed earlier today by Hans Meuer who presented the latest issue of the list of the world's most powerful computers at the Mannheim Supercomputer seminar.
For the first time in history, Europe is well represented in the upper regions with one machine in the UK and three in Germany amongst the first 11 machines. SGI/Cray is still the most important supercomputer manufacturer with 201 machines in the TOP500, followed by IBM (71), Hewlett-Packard (67) and newcomer SUN (60). The only European vendor is Parsytec with 2 machines. American vendors dominate with 427 computers.

- SuParCup '97 awarded to chemical application on parallel platforms
- Ad Emmen
- After reviewing the 17 entries submitted, the SupArCup'97 Committee chose Bernd Pfrommer of the University of California as this year's winner. This was announced at the special SupArCup'97 session at the Mannheim Supercomputer Seminar.
Pfrommer calculated NMR chemical shift calculations with a new method on several parallel platforms, including Cray T3E, SGI Power Challenge, and IBM SP2. Second prize was for numerical wind tunnel simulations from a joint German/Japanese team and third prize for a molecular dynamics application on several parallel computers by Stadler from the university of Stuttgart. Student prize was for a Fast Solver for Incompressible Flows, from Oswald, university of Heidelberg.

Atlantic news
- High Performance Computing in the U.S. an analysis based on the Top500 list
- Uwe Harms
- Based on the Top500 list, Horst Simon, Director of NERSC Berkeley (Lawrence Berkeley Nat. Lab.), analysed the present situation in America and discussed the major trends in architecture and technology, vendors, federal funding and support for HPC. He underlined the U.S. dominance of the World Wide HPC market and detailed the market penetration by technology and architecture.

- Experiences with a Tflop/s machine - ASCI Red
- Uwe Harms
- The Accelerated Strategic Computing Initiative (ASCI) focuses on advancing three-dimensional, full-physics calculations up to "full-system'' simulation - applied to virtual testing. Involved are Sandia, Los Alamos and Lawrence Livermore National Laboratories. ASCI relies on the use of massively parallel supercomputers initially capable of delivering over 1 Tflop/s to perform such demanding computations.
The ASCI "R'' machine at Sandia consists of over 4500 nodes (over 9000 processors) with a peak computational rate of 1.8 Tflop/s, 567 GBytes of memory, and 2 TBytes of disk storage. There are many new issues to consider in the use of MPPs in a "production'' environment, e.g. parallel I/O, mesh generation, visualisation, archival storage, high-bandwidth networking and the development of parallel algorithms. Mark Christon discussed the issues and lessons learned to-date on the ASCI Red machine.
