    Grid computing: A new dimension of the Internet
    (Informatik bewegt: Informatik 2002 - 32. Jahrestagung der Gesellschaft für Informatik e.v. (GI), Ergänzungsband, 2002) Gentzsch, Wolfgang
    The Grid is a distributed computing architecture for accessing Computing, data resources and scientific instruments over the Internet, in much the same way that electricity is delivered over thePower Grid today. It is the next logical step, from Internet, to WorldWide Web, now to technology infrastructure which connects distributed computers, storage devices, mobile devic es, instruments, sensors, data bases, and software applic a- tions, and provides uniform access for the user community. The Grid is the evolving next generation of the Advanced Web, for computing, collaboration and the NSF NCSA Na- tional Technology Grid; NetSolve for accessing and sharing mathe matical software; Nimrod for campus-wide resource sharing; SETI@Home for searching for extraterrestrial intelligence; the CERN DataGrid, processing Petabytes of particle data per year (starting in 2006) from its Large Hadron Collider experiment; or the APGrid connecting many computer centers in Asia and the Pacific Rim, in the near future.

    Keynote Speaker e-Infrastructures for e-Science
    (Grid service engineering and management – the 4th international conference on grid service engineering and management – GSEM 2007, 2007) Gentzsch, Wolfgang
    Nowadays, proprietary and monolithic IT environments are more and more transformed into standard- and component-based service infrastructures. In this keynote, we will analyse this trend especially for the area of e-Science. While in the past decades, scientist have developed centralised, application-focused (silo-oriented) hardware and software environments, they now (for good reasons) tend to join forces in building and operating general-purpose, networked, distributed compute and data grids, recently called e-Infrastructures. This trend is enabled by grand technology progress towards reusable, decomposable, service-oriented software architectures and standard off-the-shelf hardware, among others. However, it is still challenging to design, build, and operate such complex infrastructures for e-Science. Therefore, we have analysed several major (grid) infrastructure projects around the world (such as TeraGrid in the US, NAREGI in Japan, the e-Science Initiative in the UK, and DEISA and EGEE in Europe) for the sole purpose of extracting their lessons learned and valuable recommendations to be followed while designing, building, and operating our own German D-Grid infrastructure and user and provider communities. This keynote will present these findings combined with our own lessons learned. A catalogue of recommendations for those interesting in building similar e-infrastructures will conclude this presentation.

    Service infrastructures for research: supercomputers, grids, and clouds, and the DEISA example
    (INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 1, 2010) Gentzsch, Wolfgang; Lederer, Hermann
    In the following, we will summarize the latest developments in the areas of Grid and Cloud Computing. With the aid of the EU funded project DEISA (Distributed European Infrastructure for Supercomputing Applications), we will explain design, development, and use of e-Infrastructures, and application enabling and implementation. The second part will briefly present three science applications and their results achieved on the DEISA HPC infrastructure, in the areas of Fluid Turbulence, Lattice Quantum Chromodynamics, und Multiprotein Complexes. We will also explain the implementation of the application codes on and optimization for the distributed DEISA HPC Infrastructure.
