Demonstrations at the HLRS Booth (R 304) at SC'99

The presentations at the HLRS booth will cover the continued collaboration with our partners at Sandia National Laboratories (SNL), the Pittsburgh Supercomputing Center (PSC), Electrotechnical Laboratory (ETL) in Japan and Manchester Computing Centre (MCC) . We aim to bring together computing resources and software of PSC, SNL, ETL, MCC and HLRS. An example is the coupling of the Cray T3E's at PSC, MCC and HLRS with an SR8000 at the ETL for running metacomputing applications.

Results of this collaboration will be partly visualized in a distributed virtual environment based on the work between the SNL's Interaction Laboratory

Scenarios planned for demonstration:

SNL will kindly provide most of the equipment for the HLRS/SNL collaboration booth. We plan to run our demos in an environment involving MPPs, workstations and a cluster of PC's. Results of some of the simulations will be visualized online. Since the demonstrations rely partly on the availability of machines at three different supercomputing centers, we will have to schedule them for a fixed date and time and will not be able to show online demonstrations on demand. These demonstrations are currently planned:

  • Fluid Dynamics Simulation of the reentry of a space vehicle (URANUS)
  • Simulations of the mechanical stability of quasi-crystals in three dimensions (IMD) :
    Abstract
  • Simulations of dilute (P3T-DSMC) and dense (P3T-MD) granular systems:
    Abstract
  • High Performance simulation of internal combustion engines (HPS-ICE).

Tools and Applications used:

The planned demonstrations will be made possible and supported by tools and applications developed at HLRS and the partner institutions:

PACX-MPI (PArallel Computer eXtension) aims to provide MPI programmers with a single system view of a cluster of MPPs.
 
URANUS (Upwind Relaxation Algorithm for Nonequilibrum flows of the University of Stuttgart) has been developed for the simulation of nonequilibrium flows around reentry vehicles in a wide altitude-velocity range.
 
P3T-DSMC A parallel object-oriented simulation Monte Carlo code.
 
 
IMD is a software package to perform classical molecular dynamics simulations. As such it iteratively solves Hamilton's equations of motion for a system of point masses for some time interval.
 

COVISE (COllaborative VIsualization and Simulation Environment) aims to allow distributed visualization, collaborative working and distributed simulation in a HPCN environment.
 

COVER, the COVISE Virtual Reality environment allows interactive steering and analysis of scientific data using projection based VR equipment.
