Demonstrations at the HLRS Booth
HLRS Presentation at SC 2000 in Dallas/Texas
At SC2000 HLRS will demonstrate its activities in the field of Grid Computing or Metacomputing. Our presentation will show the main building blocks HLRS is working with. Several projects highlight how these blocks are put together. This includes computers, networks, middleware and applications. To show the potential of the resulting framework HLRS will integrate computing resources at Sandia National Laboratories (SNL), Pittsburgh Supercomputing Center (PSC), Tsukuba Advanced Computing Center (TACC)/Japan, Manchester Computing Centre (MCC), National Center for High Performance Computing (NCHC)/Taiwan, Japan Atomic Energy Research Institute (JAERI)/Japan
Scenarios planned for demonstration:
SNL will kindly provide most of the equipment for the HLRS/SNL collaboration booth. A number of projects are demonstrated that focus on designing and implementing middleware components, on putting them together to create a framework for grid computing and on running applications to exploit the potential of such frameworks.
- PACX-MPI (PArallel Computer eXtension) allows to extend the functionality of native MPI implementations to clusters of MPPs and PVPs. PACX-MPI has been recently extended to cover the complete MPI1.2 standard. The optimizations regarding global communication have been improved.
- COVISE (COllaborative VIsualization and Simulation Environment) is a visualization software that was developed in several European projects. It aims to allow distributed visualization, collaborative working and distributed simulation in a HPCN environment.
- METODIS (METODIS (MEtacomputing TOols for DIstributed Systems) aims at developing an ATM API, a metacomputing MPI and a metacomputing version of VAMPIR to further promote the usage of distributed systems. In a second step these tools shall be integrated to form the core of a tool box for technical simulation in metacomputing.
- GTS (Gigabit Testbed South) is a p roject that links research institutes at Berlin, Erlangen/Nuernberg and Munich via a 2.4 Gbit network connection. In the frame of this test bed HLRS provides PACX-MPI as the metacomputing MPI library for wide area simulations.
- Blood flow simulation is a project that was only recently started together with the University hospital at Ulm. The purpose is to set up a framework between the two institutions. CT data are created at Ulm and are transformed into 3D-representations of arteries. Using automatic mesh creation the flow of blood in the arteries is simulated at Stuttgart and data are prepared for visualization. This shall help surgeons to improve the quality of their work.
- URANUS (Upwind Algorithm for Nonequilibrium Flows of the University of Stuttgart) has been developed to simulate the reentry phase of a reusable space vehicle in a wide altitude velocity range. The parallel multiblock program is able to run on several hundreds of processors and is used as an example application for the metacomputing testbed.
- HLRS will also show the collaboration with the John von Neumann Institute for Computing (NIC) (see http://www.fz-juelich.de/nic/sc2000.html) that extends to the collaboration in the field of seamless computing (UNICORE), gigabit networking and common use of software, developed by the two centers.
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) allows to extend the functionality of native MPI implementations to clusters of MPPs and PVPs. PACX-MPI covers the complete MPI1.2 standard.
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.
COVISE (COllaborative VIsualization and Simulation Environment) aims to allow distributed visualization, collaborative working and distributed simulation in a HPCN environment.
