Heidelberg, The advanced registration ends on May 9, which saves you as a regular participant 200 EURO and University Personnel 110 EURO. A similar amount of money can be saved for the Tutorial : Cybersecurity. Some of the high-lights of the Tutorial , 24. June, and the Conference, 25. June to 27. June, as well as the web-site are listed in this article. Tutorial - June 24 Its theme is Cybersecurity - how to protect large computer centers. It gives an overview on the stare-of-the-art of IT security, with regards to big computer centers. It treats the most common and dangerous threats and discuss in detail the three fundamentals Prevention, Detection and Response. It is given by Christoph Fisher, BFK edv-consulting, Karlsruhe, Germany, and Bryan T. Koch, RxHUB, Saint Paul, USA. The Conference, June 25 to June 27 This years conference moved its beginning from Thursday to Wednesday and its end from Saturday to Friday. Thus the participants have one day more, if they want to stay for the weekend in the pretty town of Heidelberg. Wednesday, June 25 As usual since its beginning in 1986, Hans Meuer presents the fastest supercomputers. In the early beginning the list consist of a slide in DIN A4. In 1993 he moved to the Top500 list. This year he discusses the June 2003 list, the 21st edition. There will surely be no surprise, as the Earth Simulator, built by NEC, is clearly the number one. But the marketing specialists of the hardware vendors will listen very carefully to write press releases with the leading vendor in numbers, in Linpack performance, in the top 10, in the top 100, in clusters etc. A highlight will be Jim Gray's talk on the World Wide Telescope as a Prototype for how Computation is Revolutionizing Science. Some time ago I interviewed Jim Gray concerning his view on numerical simulation and handling and analyzing huge data sets. The focus of this Wednesday is the HPC Key Application: Earth System Modeling. Here high-level speakers from the Max-Planck-Institute for Meteorology, Hamburg, the Head of DKRZ, Hamburg, from NCAR, ECMWF and the Earth Simulator present their experiences, models and targets. The talks are followed by a Panel Discussion of the speakers. The day ends with a comparison of HPC in Asia and Europe, specifically the UK strategy. The come together party takes place in the exhibition venues and the conference area. As usual this is very specific to this Conference, wonderful discussion, meetings of HPC friends and getting new contacts. Thursday, June 26 Although the come together party ends late, Hans Meuer powers the participants by an early start, 8.15 a.m. But getting up is a must, as the early morning focusses on „The Death of SuperComputer Centers and Birth of SuperData Centers. Different views from DB Systems (German Railway), CERN, German Telekom and from RxHUB, Saint Paul, USA. This part is followed by HPC and Biocomputing. Here research and industry present their approach. IBM discusses the BlueGene Initiative. After lunch, the Earth Simulator System: Its Impact on the US Funding Strategy, is the focus. Horst Simon, NERSC, will present the Divergence Problem in HPC. Having a short refreshment, the most stressed part begins. Only „hardcore" fans keep on staying in the. „HPC Manufacturers in the Hot Seat". It was renewed, as now 16 short product and development presentations will be given by the vendors, which are asked by 8 Inquisitors critical and fundamental questions - I belong to them - hihi. But in the following „Above the Castle" Party all the criticisms and hard questions will be forgotten. Friday, June 27 This day focusses on off-the-shelf processors for HPC. Microprocessor technology will by highlighted by Sun, AMD - Opteron- and IBM - Power4. The keynote will be given by Justin Rattner, Intel, building efficient HPC systems from catalog components. The presentations will be followed by a panel discussion: Off-the-Shelf Processor - a Must for HPC Systems? Here panelists from IBM, HP, AMD, Linux NetworX, Intel, Cray, Myricom and Sun show their view in the hardware arena. The software aspect is covered by the final session: Terascale Computing, Will Software be the Achilles Heel ? Software experiences at Nat. Aerospace lab, Tokio, the scalability matters in Brisbane, Australia, and the interdependencies of architecture and software is the topic in the California Institute of Technology. The conference ends with a soup and it begins the waiting for 2004. Exhibition There are two parts of exhibitors, industrial exhibitors are for example Acconovis, Adic Germany, AMD, Bull, CPI, Cray Computer, Dell Computer, Dolphin, Dr. Koch Computertechnik, Fujitsu Siemens Computers, Gelato Federation, Hewlett-Packard, IBM, Intel, Linux Networx, Megware Computers, Myricom, NAG, NEC, Nallatech, Pallas, ParTec, Platform Computing, RackSaver, SGI, Sun Microsystems, TGS-Telonic and T-Systems Solutions for Research.
