Navigation and service


Regional testbed in Nordrhein-Westfalen


The project RTB-NRW is working towards the utilization of broadband communication networks and services within the German research community. For this purpose, institutes participating in the RTB-NRW are connected by private 34-Mbps-ATM-Links (Asynchronous Transfer Mode). Besides others, the RTB-NRW supports the following two applications which make use of these high speed networks:

  • Subproject EURAD: Tools for visualization and animation of large, multi-dimensional arrays
  • Subproject Metacomputer: Distributed massively parallel computer

Partners / Grants

  • RWTH Aachen
  • University Bonn
  • University Köln
  • DLR, Köln-Porz
  • Gesellschaft für Mathematik und Datenverarbeitung (GMD), Institut für Algorithmen und Wissenschaftliches Rechnen, Birlinghoven
  • Central Institute for Applied Mathematics, Forschungszentrum Jülich

The project was funded by the German Federal Ministry of Education and Research (BMBF) and DFN.

The grant period was September 1994 until December 1996.

Subproject EURAD

The RTB-NRW project EURAD is aiming at preparation and use of tools for visualization and animation of large multi-dimensional arrays of variables. Application data are derived from the numeric simulation of transport and transformation processes in the atmosphere. The project is looking for a significant reduction in time consume because of the reduced communication delays. In addition improved data security and reduced storage requirements are expected by regional data storing.

Subproject Metacomputer

Recently it has been shown by American supercomputer centers that the combined computing power of two different supercomputers working on one program at the same time can lead to very effective solutions in certain cases. The special topic of the RTB-NRW metacomputer project is therefore the combined, simultaneous utilization of two different supercomputers, one located at the Research Centre Jülich (ZAM), the other at the GMD in Sankt Augustin. Using the capacities of the ATM connection between both sides, it shall be examined, whether such a metacomputer, consisting of geographically distributed supercomputers, has significant advantages compared to the use of single systems. The work is based on an application program for the simulation of the transport of harmful chemicals in the soil.
